## Findings

- **info** The word "credentials" in `brainkb_login` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credentials".

description: "Authenticate to BrainKB with the user's credentials and cache the JWT for THIS session..."
```


## Deletes or cancels (7)

Removes, cancels or revokes something. Claude Code: deny.

### `brainkb_delete_space`

- The name "brainkb_delete_space" says "delete": a word for removing or ending something.
- The description says "PERMANENTLY delete".

Description, as the server wrote it:

```untrusted-server-text
PERMANENTLY delete a space and everything in it. SuperAdmin only; irreversible.

    Drops the space's named graphs and the ingestion-history (delta) graphs that
    hold copies of their data, removes the graphs' registry entries and the space's
    RDF manifest, and deletes the space with its members, access rules, search
    entries and SynthScholar reviews (with their kept files). EVERY SUBSPACE below it,
    at any depth, is deleted the same way, deepest first (`subspaces_deleted`). Each
    deletion is kept in the provenance graph (who, when, which graphs:
    prov:invalidated). `confirm_slug` must equal `slug`.

    Before calling: show the user the space AND its subspaces (brainkb_space_tree)
    and what will be lost, and get their explicit confirmation in this conversation.
    Never call it to tidy up on your own initiative. A non-SuperAdmin caller gets
    403; if a step fails (502) the message says which spaces were already deleted —
    the rest is untouched and it is safe to retry.
```

### `brainkb_discard_upload`

- The name "brainkb_discard_upload" says "upload": a word for a change.
- The description's first verb is "delete": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
Delete one of your staged uploads without ingesting it.
```

### `brainkb_remove_access_rule`

- The name "brainkb_remove_access_rule" says "remove": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
(Space manager) Delete a fine-grained access rule by its id
    (see brainkb_list_access_rules).
```

### `brainkb_remove_role`

- The name "brainkb_remove_role" says "remove": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
(Admin) Remove a role/group from a user by email.
```

### `brainkb_revoke_capability`

- The name "brainkb_revoke_capability" says "revoke": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
(Admin only) Revoke a previously granted capability from a user.
```

### `brainkb_revoke_role_capability`

- The name "brainkb_revoke_role_capability" says "revoke": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
(Admin only) Revoke a capability from a role/group.
```

### `brainkb_revoke_token`

- The name "brainkb_revoke_token" says "revoke": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
Revoke one of your Personal Access Tokens by id (see brainkb_list_tokens).
    Takes effect immediately — the next call using that token fails.
```

## Changes things (43)

Creates or changes something that can be changed back. Claude Code: ask.

### `brainkb_activate_user`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
(Admin) Activate a user's account (sets the JWT user active) by email.
```

### `brainkb_add_access_rule`

- The name "brainkb_add_access_rule" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
(Space manager) Restrict a space action to a subject.
    action: 'read' | 'write' | 'manage'.
    subject_type: 'global_role' (e.g. 'Admin','Lab Member') | 'member' (an email) |
    'space_role' ('viewer'|'editor'|'owner', matched as >=).
    When rules exist for an action, only matching callers may perform it; the space
    owner and Admin/SuperAdmin always bypass (no lockout). Example: restrict writing
    to Admins -> action='write', subject_type='global_role', subject_value='Admin'.
```

### `brainkb_add_space_graph`

- The name "brainkb_add_space_graph" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Register a named graph and bind it to a space, so ingest/read on that graph
    are governed by the space's membership and visibility. Owner/editor only.
    The named_graph_iri is **globally unique** — one graph belongs to exactly one
    space. If it's already registered (to any space) the call returns 409; graph
    bindings are permanent (no unregister/delete).
```

### `brainkb_add_space_member`

- The name "brainkb_add_space_member" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Add/update a space member. role: 'owner' | 'editor' | 'viewer'. Owner only.
```

### `brainkb_assign_role`

- The name "brainkb_assign_role" says "assign": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
(Admin) Assign a role/group to a user by email (e.g. 'Lab Member', 'External',
    or a custom group). The user must already have a profile (created on first
    login/registration). NOTE: assigning the 'Admin'/'SuperAdmin' role is
    SuperAdmin-only (hierarchy: SuperAdmin > Admin).
```

### `brainkb_available_roles`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
(Admin) List the available roles/groups (Admin, Lab Member, Curator, …).
```

### `brainkb_ban_user`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
(Admin) Ban a user by email (reversible; preserves history). This is how
    accounts are removed — there is NO hard delete. Banning an Admin is
    SuperAdmin-only; SuperAdmin accounts cannot be banned.
```

### `brainkb_capabilities`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
(Admin only) Show a user's roles, effective capabilities, and delegated
    grants. Useful to check why someone can/can't create team spaces, ingest, etc.
```

### `brainkb_create_permission`

- The name "brainkb_create_permission" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
(Admin) Create a new usermanagement permission, e.g.
    name='dataset.export', resource='dataset', action='export'. Attach it to roles
    via the usermanagement role-permissions API.
```

### `brainkb_create_role`

- The name "brainkb_create_role" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
(Admin) Create a new role/group — e.g. an 'External' collaborator group —
    which can then be assigned with brainkb_assign_role.
```

### `brainkb_create_space`

- The name "brainkb_create_space" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a workspace/space, or a subspace inside one. The caller becomes owner.
    slug: lowercase/hyphen id, **globally unique** — if it's already taken the call
    returns 409 (pick another slug).
    visibility: 'private' or 'public' (set per space: a private space may hold a
    public subspace);
    description: short human description (recommended — surfaces in the registry);
    space_type: 'individual' (a personal space — any write-capable role) or 'team'
    (a shared space — only Admin/SuperAdmin, or a user granted create_team_space).
    parent_slug: create it as a **subspace** of that space (any depth). Needs the
    right to manage the parent; the subspace takes the parent's space_type, and
    everyone with a role in the parent (or above) gets the same role in it. A
    subspace can't be moved to another parent later.
```

### `brainkb_create_token`

- The name "brainkb_create_token" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Generate a Personal Access Token (PAT) for browser-free auth. Requires you
    to be logged in already (brainkb_login or brainkb_globus_login). The token is
    shown ONCE and never again — copy it and set it as BRAINKB_TOKEN in your
    MCP/skill config; then no login or browser is needed until it expires.
    `name`: a label so you can tell tokens apart (e.g. 'laptop'). `days`: lifetime
    (default 90, server-capped). Treat the returned token like a password.
```

### `brainkb_deactivate_user`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
(Admin) Deactivate a user's account by email.
```

### `brainkb_delta`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
The exact triples a job added (its delta), as JSON-LD.
```

### `brainkb_delta_history`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
A named graph's change history: one entry per ingest delta (job, triple
    count, timestamp), newest first.
```

### `brainkb_finish_login`

- The input takes a statement or command to run (input.code), which can change anything it can reach.

Description, as the server wrote it:

```untrusted-server-text
Complete an OAuth login started with brainkb_globus_login by exchanging the
    one-time code shown in the browser for a session token. The code is single-use
    and never echoed back.
```

### `brainkb_globus_login`

- The description's first verb is "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Start an OAuth login (Globus / ORCID / GitHub) for THIS session — use this
    instead of brainkb_login when the user signs in with Globus rather than a
    password. Returns a URL to open in a browser; after signing in, the page shows
    a short one-time code — pass it to brainkb_finish_login(code) to complete.
    (The browser step is unavoidable: only the user can consent at the provider.)
```

### `brainkb_grant_capability`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
(Admin only) Delegate a capability to a user — e.g. 'create_team_space' or
    'manage_team_space' so a Curator/Lab Member can create/manage team spaces.
    Grantable: create_private_space, create_team_space, manage_team_space, ingest,
    recover, read_private (NOT the admin-only 'grant'/'sparql_admin').
```

### `brainkb_grant_role_capability`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
(Admin only) Grant a capability to a whole role/group so EVERY member gets
    it — e.g. give a custom group 'uk_collaborator' the 'ingest' or
    'create_private_space' capability. Grantable: create_private_space,
    create_team_space, manage_team_space, ingest, recover, read_private (NOT the
    admin-only 'grant'/'sparql_admin'). Create the group first with
    brainkb_create_role, then assign it to users with brainkb_assign_role.
```

### `brainkb_ingest_files`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Ingest local RDF files (ttl/nt/nq/rdf/owl/jsonld/json) into a named graph.
    Returns a job_id; runs in the background — poll with brainkb_job_status.
```

### `brainkb_ingest_text`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Ingest raw RDF text (Turtle / N-Triples / JSON-LD, auto-detected) into a
    named graph. Returns a job_id; ingestion runs in the background — poll with
    brainkb_job_status. The graph must be registered (see brainkb_add_space_graph)
    and the caller must have write access to its space.

    `sha256` / `expected_bytes` are an integrity contract, and you should use them
    whenever the RDF came from a file. Ingest is append-only — no delete for
    triples, no unregister for a graph — so RDF that arrives here mangled is
    permanent. Because `data` is a string, it passes through the caller's context,
    where dense Turtle is exactly what gets silently altered: ligatures, Greek
    letters, embedded newlines, escaped quotes. Declare the digest of the bytes you
    MEANT to send (`shasum -a 256 file.ttl`) and this refuses the write on any
    mismatch, turning an unrecoverable corruption into a clean rejection.
    
```

### `brainkb_ingest_upload`

- The name "brainkb_ingest_upload" says "upload": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Ingest a file you staged with `POST /upload` into a named graph.

    This is the route for a large local file: your HTTP client streams the bytes
    straight to this server over HTTPS, then you name the resulting upload_id here. The
    server reads its own staged copy and posts it to the ingest API internally, so
    the RDF never passes through a model's context — nothing to transcribe, no
    context-window ceiling, and no reason to split the document (splitting breaks
    blank-node identity and silently detaches triples, permanently).

    Stage a file with any HTTP client — the point is that the LIBRARY reads the file,
    so the bytes never pass through a model:

        import requests, hashlib, pathlib
        f = pathlib.Path("review.ttl")
        r = requests.post(
            "https://mcp.brainkb.org/upload",
            params={"filename": f.name,
                    "sha256": hashlib.sha256(f.read_bytes()).hexdigest()},
            headers={"Authorization": f"Bearer {TOKEN}"},
            data=f.open("rb"),          # streamed — never loaded into memory
        )
        print(r.json())                 # -> {"upload_id": "up_...", "state": "staged"}

    It returns an upload_id and the sha256 the server computed — compare it with your
    own before ingesting.

    Returns a job_id; poll brainkb_job_status, then reconcile brainkb_delta(job_id)
    against the triple count you expected. The staged copy is deleted once the
    ingest API has accepted the bytes.
    
```

### `brainkb_login`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Authenticate to BrainKB with the user's credentials and cache the JWT for
    THIS session only (isolated per caller). The password/token are never echoed.

    Uses single sign-on: one login mints a refresh token, cached for THIS session,
    which is exchanged on demand for per-service access tokens (query_service,
    usermanagement, …). Falls back to a legacy per-service token if the backend
    has no SSO. On the hosted multi-user remote you can skip this and instead have
    your client send an 'Authorization: Bearer <token>' header (a refresh token
    unlocks all services).
```

### `brainkb_logout`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Forget the cached token for this session.
```

### `brainkb_provenance_graph`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
PROV-O ingestion/activity history (JSON-LD) for a named graph.
```

### `brainkb_provenance_job`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
PROV-O provenance bundle (JSON-LD) for one ingest job.
```

### `brainkb_qa_run`

- The name "brainkb_qa_run" says "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Run a canned question from brainkb_qa_list by id. `params` maps parameter
    names to values; they are validated and escaped, never spliced in raw. Runs
    through the same SPARQL endpoint as brainkb_sparql, so it needs the same
    role. Results page the same way: a query without its own LIMIT returns
    `limit` rows from `offset`, and `page.next_offset` says where to continue.
```

### `brainkb_recover_job`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Attempt to recover a stuck/errored ingest job (marks it recoverable/errored).
```

### `brainkb_reserve_graph`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
(Admin/SuperAdmin) Reserve a named graph so other users can't create it.

    match_type 'exact' reserves one graph IRI; 'prefix' reserves every IRI starting
    with it (e.g. 'https://brainkb.org/graph/allen/'). Give a `reason` — it is shown
    to anyone who is refused. Optional `space_slug` reserves it for that space, whose
    managers/editors may then bind it. Graphs already bound stay where they are; the
    response lists them under `already_bound`. 409 if it is already reserved,
    overlaps a system graph, or is bound to another space than `space_slug`.
```

### `brainkb_role_capabilities`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
(Admin only) List the capabilities granted to a role/group (e.g.
    'uk_collaborator', 'Lab Member').
```

### `brainkb_set_space_visibility`

- The name "brainkb_set_space_visibility" says "set": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Set a space 'public' (anyone, even anonymous, can read) or 'private'
    (members only). Owner only. Everything in a public space is public: making a
    space public also makes all its subspaces public, and a subspace of a public
    space cannot be made private (409). Under a private space each subspace can be
    public or private on its own.
```

### `brainkb_sparql`

- The description's first verb is "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Run an arbitrary SPARQL query. Requires an Admin/SuperAdmin role (the
    sparql_admin capability) — for ordinary questions prefer brainkb_search,
    brainkb_read_space, or the provenance/delta tools, which need no admin role.

    Large results come back a page at a time. A SELECT without its own
    LIMIT/OFFSET returns at most `limit` rows (0 = the server's page size, 500 by
    default) starting at `offset`; the response's `page` says whether there is
    more (`has_more`) and where to continue (`next_offset`). Add ORDER BY for
    stable pages. A query that sets its own LIMIT runs as written. Any result
    too big for one response is cut to its leading rows with a `truncated` note.
    Prefer COUNT(*) first when you only need to know how much there is.
```

### `brainkb_synthscholar_evidence`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Evidence spans of an ingested review: the quoted text its claims rest on, with
    the study, section, relevance, and whether the quote was matched verbatim in
    the source (`grounded`). Filter by text, claim type, PMID or grounding.
```

### `brainkb_synthscholar_ingest`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Ingest a SynthScholar review — the output directory of a run (the folder
    holding review.json and review.ttl, as the synthscholar skill writes it) — into
    a space you may write to (see brainkb_list_writable_spaces; you need to be its
    owner or an editor).

    A review is unique per space: the same run can go into several spaces, once
    each. Its graph, https://brainkb.org/synthscholar/<space>/reviews/<protocol.review_id>/,
    is registered in the space; review.ttl plus an import record (PROV-O: who, when,
    every kept file with media type, size and sha256, what was left out) are ingested
    as an ordinary job → job_id (poll brainkb_job_status, reconcile with
    brainkb_delta). Everything but work/ is kept and shown on the review's page.
    Once per review per space: the same run into the same space again is refused (409). Reads the MCP server's
    filesystem, so it follows brainkb_ingest_files' rules (MCP_INGEST_ROOT).
```

### `brainkb_synthscholar_records`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Per-study records an ingested review produced. `kind`: `charting` (the
    data-charting form's answers per study), `appraisal` (critical appraisal by
    domain) or `narrative` (narrative synthesis rows: design, methods, outcomes,
    limitations). `q`: text in the answers (e.g. "neo4j" finds the studies that
    report it); `study`: source id (S-001), title, DOI or PMID; `fields`:
    comma-separated fields to return (the response lists the available ones).
```

### `brainkb_synthscholar_screening`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
The screening audit trail of an ingested review: every decision with its
    stage (title_abstract | full_text), decision (include | exclude), what it was
    judged on (title_abstract | full_text | abstract_only), the full-text route and
    the reason. Filter by any of those, by text or criterion code in the reason
    (e.g. "EC2"), or by PMID. Also returns counts for the filtered set: by stage and
    decision, what decisions were judged on, and exclusion reasons by criterion.
```

### `brainkb_synthscholar_studies`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
The included studies of an ingested review, filtered. `q`: text in title,
    authors, journal, DOI, PMID or keywords. `full_text`: true = read in full,
    false = abstract only. `source`: full-text route (europe_pmc, unpaywall, ezproxy,
    arxiv, …). `rob`: risk-of-bias rating (low, high, some concerns). Years
    inclusive. Each study: ids, title, authors, year, journal, how it was read and
    by which route, RoB. Paged (`total`, at most 200 per call).
```

### `brainkb_synthscholar_text`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
An ingested review's own text: `abstract`, `introduction`, `synthesis`,
    `bias`, `limitations`, `conclusions`, `research_question`, `search_queries` or
    `per_group` (the per-group analysis) — or all of them when `section` is empty.
```

### `brainkb_unban_user`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
(Admin) Lift a ban on a user by email.
```

### `brainkb_unreserve_graph`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
(Admin/SuperAdmin) Remove a reservation by its id (see
    brainkb_list_reserved_graphs). System reservations cannot be removed.
```

### `brainkb_update_space`

- The name "brainkb_update_space" says "update": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Rename a space, change its description, and/or give it a new slug. Owner/manager
    only. Pass only what changes; description="" clears it.

    `new_slug` (lowercase letters, digits and hyphens, 3-64 chars) moves the space's IRI
    and every graph whose IRI is built from the old slug (https://brainkb.org/graph/<slug>/…,
    …/synthscholar/<slug>/…) to the new slug, with their registry, search and history
    records and SynthScholar reviews; graphs with other IRIs keep theirs. The old slug and
    IRIs stay as aliases: they keep resolving and nobody else can take them, but ingest
    into an old IRI is refused with the new one. The result's `rename.moved_graphs` lists
    each from → to. 409 if the slug or a target graph is taken.

    Before calling with `new_slug`: show the user the graphs that will move and confirm.
```

### `brainkb_upload_status`

- The name "brainkb_upload_status" says "upload": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
State of one of your staged/submitted uploads.

    `state` is `staged` (waiting for brainkb_ingest_upload), `submitting` (the server
    is streaming it to the ingest API), `submitted` (accepted — `job_id` is set, poll
    brainkb_job_status) or `failed` (the staged bytes were KEPT, so retry with
    brainkb_ingest_upload rather than re-uploading).
```

### `brainkb_use_token`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Use a Personal Access Token (brainkb_pat_...) for THIS session — an
    alternative to setting BRAINKB_TOKEN in the config. Validates the token, then
    caches it so subsequent calls authenticate with it. The token is never echoed.
```

## Only reads (22)

Looks things up and changes nothing. Claude Code: allow.

### `brainkb_delta_compare`

- The name "brainkb_delta_compare" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare two jobs' deltas: A-only / B-only / shared triple counts + triples.
```

### `brainkb_get_space`

- The name "brainkb_get_space" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
A space's details: graphs, members (direct, plus `inherited_members` with the
    parent space each comes from), visibility, `parent_slug`, `ancestors` (root
    first) and direct `subspaces` — only the ones the caller may see — and the
    caller's `your_role` / `role_inherited`. Public spaces need no login; member
    emails are shown to members and admins only.
```

### `brainkb_job_status`

- The name "brainkb_job_status" says "status": a word for reading.
- Tag private-data: The description's first sentence says "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Detailed status of one ingest job: status, progress %, current file/stage,
    per-file failures, and (when complete) a summary.
```

### `brainkb_list_access_rules`

- The name "brainkb_list_access_rules" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List a space's fine-grained access rules (member/manager of the space).
```

### `brainkb_list_capabilities`

- The name "brainkb_list_capabilities" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
(Admin only) Catalog of all KG capabilities, which are delegatable
    ('grantable'), which are admin-only, and a description of each. Use this to see
    the available permission options before granting to a user or group/role.
```

### `brainkb_list_jobs`

- The name "brainkb_list_jobs" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the user's ingest jobs (newest first) with status and progress.
```

### `brainkb_list_permissions`

- The name "brainkb_list_permissions" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
(Admin) List all usermanagement permissions (resource/action pairs used for
    page-access and role-permission mapping). These are the addable 'permission'
    options; KG action-capabilities are listed by brainkb_list_capabilities.
```

### `brainkb_list_registered_graphs`

- The name "brainkb_list_registered_graphs" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List registered named graphs visible to the caller (private-space graphs the
    caller can't access are hidden).
```

### `brainkb_list_reserved_graphs`

- The name "brainkb_list_reserved_graphs" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
(Admin/SuperAdmin) List reserved named graphs: graph IRIs, or every IRI under a
    prefix, that only an Admin/SuperAdmin — or, when reserved for a space, that
    space's managers/editors — may register or bind. Includes the built-in system
    reservations (BrainKB's metadata and provenance graphs), which nobody can bind.
```

### `brainkb_list_spaces`

- The name "brainkb_list_spaces" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List spaces the user can see (their own/member spaces + public ones), each
    annotated with THIS caller's permission so you know what they may do:
      - your_role: 'owner' | 'editor' | 'viewer' | null (their space membership,
                   including a role inherited from a parent space)
      - role_inherited: the role comes from a parent space, not this one
      - parent_slug: the parent space, when this is a subspace the caller can see
                     the parent of (build the tree from it)
      - is_owner:  they own the space
      - access:    'owner' | 'member' | 'public' (how it's available to them)
      - can_write: their space role permits ingest (owner/editor) — a real ingest
                   also needs the 'ingest' capability + any per-space access rules.
    Use this to tell the user which spaces they can read vs. write vs. only see as
    public.

    No login needed: an unauthenticated caller gets the public spaces only
    (read-only). Log in to also see your own/member spaces.

    `owner` is shown only for spaces the caller is a member of; a public space
    read by a non-member never exposes its owner's email.
```

### `brainkb_list_tokens`

- The name "brainkb_list_tokens" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "secret": it reads secrets.

Description, as the server wrote it:

```untrusted-server-text
List your Personal Access Tokens (metadata only — the secret is never
    shown): id, name, prefix, created/last-used/expiry, and whether each is
    active/revoked/expired. Use the id with brainkb_revoke_token.
```

### `brainkb_list_uploads`

- The name "brainkb_list_uploads" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "file": it reads files.
- Tag untrusted-input: The description's first sentence says "list" and "post": it reads posts, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
List RDF files YOU have staged with POST /upload but not yet ingested.

    Shows each upload_id, its size, sha256 and when it expires. Only your own
    uploads are visible.
```

### `brainkb_list_users`

- The name "brainkb_list_users" says "list": a word for reading.
- Tag private-data: The description's first sentence says "email": it reads mail.
- Tag untrusted-input: The description's first sentence says "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
(Admin) List users (profiles) — filter by `q` (name/email/orcid) or `role`.
    Shows profile_id, email, roles, providers, ban status.
```

### `brainkb_list_writable_spaces`

- The name "brainkb_list_writable_spaces" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Spaces the caller can ingest into, each with its graphs (and descriptions) and
    `parent_slug` for subspaces — decided by the same checks ingestion uses: owner/
    editor membership (including a role inherited from a parent space), a space write
    access rule, or Admin/SuperAdmin. `can_ingest` false means the caller has no
    write-capable role at all. `unmapped_graphs` are registered graphs in no space.
    Use this, not brainkb_list_registered_graphs, to choose where to ingest.
```

### `brainkb_qa_list`

- The name "brainkb_qa_list" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find a canned question BrainKB can answer, then run it with brainkb_qa_run.

    Prefer these over writing SPARQL: they are vetted against BrainKB's actual
    vocabulary. Discovery is two steps, so you never read every query at once:

    1. brainkb_qa_list() -> the menu: each category's name, a description of
       the questions it covers, and how many queries it has. Pick the category
       whose description matches the user's question.
    2. brainkb_qa_list(category="<name>") -> that category's queries. Each has
       `question` (what it answers), `notes` (when to use it, where parameter
       values come from, what the results mean), `params` (required ones have
       no default — ask the user rather than guess) and a working `example`.

    `search="words"` filters queries by words in their id/question/notes; use it
    alone to search every category when none of the descriptions fits.
    
```

### `brainkb_read_space`

- The name "brainkb_read_space" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read all RDF (JSON-LD) in a space's graphs. Public spaces are readable by
    anyone without logging in (read-only); private spaces require login and
    membership. Don't ask the user to log in just to read a public space.
```

### `brainkb_search`

- The name "brainkb_search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Full-text search over the knowledge graphs, access-filtered by space
    visibility. Pass `space` to scope to one workspace, omit for a full search.
    No login needed: an unauthenticated caller searches public spaces only.
    Anonymous/other users never see private-space data.
```

### `brainkb_space_tree`

- The name "brainkb_space_tree" says "tree": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
A space and every subspace below it (any depth), nested: each node has slug,
    name, visibility, the caller's role and whether it's inherited from a parent,
    and its graph count. Only subspaces the caller may see are included.
```

### `brainkb_synthscholar_find_study`

- The name "brainkb_synthscholar_find_study" says "find": a word for reading.
- Tag untrusted-input: The description's first sentence says "review": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Which ingested reviews (that you can read) include or screened a study —
    by DOI, PMID or part of its title (6+ characters) — and what happened to it in
    each: included (read in full or from the abstract) or each screening decision
    with its reason.
```

### `brainkb_synthscholar_get_review`

- The name "brainkb_synthscholar_get_review" says "get": a word for reading.
- Tag private-data: The description's first sentence says "file": it reads files.
- Tag untrusted-input: The name "brainkb_synthscholar_get_review" says "get" and "review": it reads comments, which other people can write. The description's first sentence says "review": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
One ingested review: summary, its graph and space, the files kept (path,
    kind, media type, size, sha256), the run's search log and verification, the
    screening basis and full-text retrieval. Long texts and the per-study list are
    left out here — read them from the graph or the review page.
```

### `brainkb_synthscholar_list_reviews`

- The name "brainkb_synthscholar_list_reviews" says "list": a word for reading.
- Tag untrusted-input: The name "brainkb_synthscholar_list_reviews" says "list" and "review": it reads comments, which other people can write. The description's first sentence says "review": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Ingested SynthScholar reviews you can read (public spaces: anyone): id, title,
    research question, space, graph, included count, when ingested, ingest job.
    `q` filters on text in the title or research question.
```

### `brainkb_whoami`

- The name "brainkb_whoami" says "whoami": a word for reading.
- Tag private-data: The description's first sentence says "email": it reads mail.
- Tag untrusted-input: The description's first sentence says "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Report the current caller's auth state (email, authenticated, and when the
    cached session expires). When signed in it also returns base_url — the backend
    THIS SERVER talks to, which on a hosted deployment is an internal address and
    says nothing about the caller's own machine.
```
