## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (2)

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

### `delete_page`

- The name "delete_page" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Delete a page: its URL stops working at once. The maker gets only a brief undo in the dashboard, then it is purged for good (there is no restore tool). Only use it when the human asked for deletion; to hide a page reversibly, use unpublish_page instead. Returns { ok, id, deleted }; fails with page_not_found if the id is not in this space or is already deleted.
```

### `update_page`

- The name "update_page" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Replace the content of an existing page in place: the same URL serves the new content immediately, so links the human already shared keep working. Use this instead of publish_page whenever the page already exists. The previous version stays restorable from the dashboard for 7 days (Pro keeps full version history). Pass draft: true to stage the update instead: nothing changes for viewers until the maker reviews the previewUrl and presses "Sync to live"; use it when the human asked to see changes before they go out. Fails with page_not_found if the id is not a live or offline page in this space.
```

## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `publish_page`

- The name "publish_page" says "publish": a word for a change that another call does not undo.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The name "publish_page" says "publish": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Publish a new HTML (or Markdown) page to the maker's PubSpace space and get back a live, shareable URL to hand to the human. Pages are unlisted by default — indexed by search engines only if the maker turns that on later (Pro); anyone with the link can view. Use this only for a brand-new page; to change a page that already exists, call update_page so its URL stays the same (find the id with list_pages). Each call creates a page that counts toward the plan's live-page cap; at the cap the call fails with doc_limit_reached and, on the free plan, an upgrade link to relay to the human. Returns { url, id, mode, visibility, dashboardUrl }.
```

## Changes things (3)

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

### `create_account`

- The name "create_account" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Sign your human up for a free PubSpace space (no card) without leaving this session. Callable without an API key. Only call it after the human has told you their email and chosen a space name; never invent or guess either. Their pages will live at <subdomain>.pubspace.ai, so treat the name as permanent (renames are limited). A 6-digit verification code is emailed to them: ask them to read it to you, then call verify_email. Once verified, publish_page works in this same session. Returns { subdomain, email, apiKey, verificationRequired, connectHint }; persist the key with the connectHint command so future sessions start connected. Fails with email_taken (they already have an account: have them sign in and copy their key from Settings → Connect your agent), subdomain_taken, invalid_subdomain, invalid_email or rate_limited. If this session is already connected with a key, it fails with already_connected.
```

### `unpublish_page`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Take a page offline without deleting it: its URL shows an "offline" notice to viewers, and the content, id, URL and view count are kept. Pass restore: true to put it back online at the same URL. Prefer this over delete_page when the human wants a page hidden or paused. Calling it twice is harmless. Returns { ok, id, live }; fails with page_not_found if the id is not in this space.
```

### `verify_email`

- 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
Finish account verification with the 6-digit code PubSpace emailed to the human (ask them to read it to you). Publishing unlocks on success. Works in the session where create_account ran, or with an API key for an unverified account. Returns { ok, verified, subdomain }; fails with invalid_code (and attemptsRemaining), code_expired, too_many_attempts or already_verified.
```

## Only reads (2)

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

### `get_page`

- The name "get_page" says "get": a word for reading.
- Tag private-data: The description's first sentence says "fetch" and "email": it reads mail.
- Tag untrusted-input: The description's first sentence says "fetch" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Fetch one page by id: metadata always ({ id, title, url, project, views, live, workEmailGated, hasDraft, createdAt, updatedAt, visibility }), plus the stored HTML when include_html is true. Read-only. Use it to read a page before editing it with update_page; use list_pages to find ids or browse. Fails with page_not_found if the id is not in this space or the page was deleted.
```

### `list_pages`

- The name "list_pages" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "email": it reads mail.
- Tag untrusted-input: The description's first sentence says "list" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
List every page in the maker's space, newest first, with no paging: { total, pages: [{ id, title, url, project, views, live, workEmailGated, hasDraft, createdAt, updatedAt }] }. Read-only. Use it to find a page_id before update_page / get_page / unpublish_page / delete_page, or to reuse an existing project name. Offline pages are included (live: false); deleted pages are not. Pass q to search instead of scanning the full list; use get_page when you need one page's HTML.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `pubspace`:

```json
{
  "permissions": {
    "allow": [
      "mcp__pubspace__list_pages",
      "mcp__pubspace__get_page"
    ],
    "ask": [
      "mcp__pubspace__publish_page",
      "mcp__pubspace__unpublish_page",
      "mcp__pubspace__create_account",
      "mcp__pubspace__verify_email"
    ],
    "deny": [
      "mcp__pubspace__update_page",
      "mcp__pubspace__delete_page"
    ]
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__pubspace__publish_page`: untrusted-input, outbound
- `mcp__pubspace__update_page`: untrusted-input
- `mcp__pubspace__list_pages`: private-data, untrusted-input
- `mcp__pubspace__get_page`: private-data, untrusted-input

- **high** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 4 tools that change things (2 destructive, 1 irreversible, 1 write). Whether a call also works without credentials was not tested: tools are never called.

https://pubspace.ai/mcp: tools/list returned 6 tools to an anonymous client, including update_page (destructive), delete_page (destructive), publish_page (irreversible), unpublish_page (write)
