```


## Deletes or cancels (4)

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

### `apply_clone`

- The name "apply_clone" says "apply": 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.
- Findings: high sensitive-path

Description, as the server wrote it:

```untrusted-server-text
Apply the Workbench profile to a target: clone the repo and install missing components (OpenCode CLI, Node/pnpm, MCP servers, skills, plugins, optional Docker). It OVERWRITES `<home>/.config/opencode/opencode.json`, copies `AGENTS.md`, resets an existing profile repo to `origin/main`, and runs global installs that need write permission (plus SSH for `mode:ssh`) and can take minutes. Writes a names-only `~/.env.workbench` (mode 600); never secret values. Consent-gated and idempotent: without `confirm:true` it returns the plan and changes nothing. Parameter semantics: `components` defaults to required+core; `workspace` defaults to `~/opencode-workbench`; `skipRepo` skips the clone/update; `profileUrl` overrides the git remote; `dryRun` returns the plan. To preview only, use plan_clone.
```

### `install_component`

- The name "install_component" says "install": 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
Install a single Workbench component by id (e.g. `node`, `opencode`, `npm-mcps`, `skills`) on a target; `component` must be an id from describe_workbench. Overwrites that component's files when present (e.g. `skills`/`plugins` replace the copies under `<home>/.config/opencode`); global installs need write permission and can take minutes. Idempotent and consent-gated: without `confirm:true` it returns the plan. Parameter semantics: `component` is required; `workspace` defaults to `~/opencode-workbench`; `confirm` defaults to false (plan only). Use it for one targeted component; use apply_clone to install the full default set.
```

### `remove_component`

- The name "remove_component" says "remove": 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
Uninstall one Workbench component by id from a target — the inverse of install_component — for a bounded, documented subset with an automated uninstall (e.g. `opencode`, `pnpm`, `npm-mcps`, `skills`, `docker-containers`); `component` must be an id from describe_workbench. Idempotent: an already-absent component reports `absent`; a component with no automated uninstall (system packages such as git/curl/node) reports `manual`. Destructive and consent-gated: without `confirm:true` it returns a preview and changes nothing, and it deletes only that component's files — never `opencode.json` or the profile repo. Parameter semantics: `workspace` sets the profile path some removals need; `dryRun` reports without changing. Use it to tear down one component; for several, call it per id.
```

### `update_component`

- The name "update_component" 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
Update one Workbench component in place by id: re-run its install script to fetch the current version (e.g. `opencode` re-runs the official installer; `npm-mcps` reinstalls the latest globals). It OVERWRITES the component's files, needs write permission, and can take minutes for global installs; the resolved version may change. Parameter semantics: `component` must be an id from describe_workbench; `workspace` defaults to `~/opencode-workbench`; `dryRun` previews; `confirm` defaults to false — set `confirm:true` to apply. For the whole profile use apply_clone.
```

## Changes things (2)

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

### `run_auth_flow`

- The name "run_auth_flow" says "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: info credentials-mention, info credentials-mention, info credentials-mention, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Return the acquisition plan for one credential on a target: the provider URL, the exact non-interactive command when one exists (e.g. `opencode auth login`, `opencode mcp auth vercel`, `gh auth login`), and whether it is already present. Read-only and value-blind: it emits guidance and re-checks presence with one read-only probe; it does not run the commands or handle secret values. Parameter semantics: `var` must be an env var name returned by list_required_credentials (unknown names error); `target` selects the machine and its `home` is where the value should be written. Use it for a single credential; it does not replace that listing.
```

### `verify_clone`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: high sensitive-path

Description, as the server wrote it:

```untrusted-server-text
Re-check a target after a clone: return a per-component `present`/`missing` list plus whether `opencode.json` and `~/.env.workbench` exist. Read-only and idempotent: it runs a detection probe (SSH or local) and checks files, writing nothing. `target` selects the machine (`local` or SSH) and its `home` is where the `opencode.json` and `~/.env.workbench` checks run; `components` restricts the check to those ids (omit it to check every component, the default); `workspace` sets the profile path used by component checks. Use it after apply_clone and after component changes; for a pre-clone preview use plan_clone.
```

## Only reads (4)

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

### `describe_workbench`

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

Description, as the server wrote it:

```untrusted-server-text
Describe this MCP server from its bundled profile without contacting any target or making a network call: repository URL, the default component set, components grouped by tier (required/core/optional), and optional MCP add-ons. It takes no parameters, is always safe, and returns instantly. Use it first to resolve a component id for install_component/remove_component/update_component or to see available add-ons; use inspect_target for a machine's live state.
```

### `inspect_target`

- The name "inspect_target" says "inspect": a word for reading.
- Tag private-data: The description's first sentence says "credential": it reads secrets.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Probe one Linux machine — this host (`local`) or a remote host over SSH (`ssh`) — and report its OS, kernel, architecture, package manager, Node/npm, OpenCode, Docker, and per-tool detection flags, plus the names (never values) of credentials present. Read-only: it runs one shell probe as the target user (over SSH when `mode:ssh`), installs nothing, writes nothing, contacts no external service, and can take a few seconds per hop. Parameter semantics: `target.mode` selects local vs ssh (default `local`); `target.host` is required only for ssh; `target.user` defaults to the ssh config/current user; `target.cwd` sets the directory for relative checks; `target.port`/`identityFile` pass straight to ssh. Use it to see what a clone would touch, then plan_clone to turn that into an ordered plan and apply_clone to perform it.
```

### `list_required_credentials`

- The name "list_required_credentials" says "list": a word for reading.
- Tag private-data: The name "list_required_credentials" says "list" and "credential": it reads secrets. The description's first sentence says "list" and "credential": it reads secrets.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: info credentials-mention, info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
List the credentials the profile references, which the target already provides, and how to acquire each missing one. Value-blind: it reads only whether each env var is set — no values, no network, no writes — via one read-only probe. Parameter semantics: `target` selects the machine (`local` or SSH) and its `home` sets the returned `template` path and the env file the presence check reads; there are no other parameters. Returns `present`/`missing` var-name arrays plus one guidance record per credential (`var`, `purpose`, `url`, `method`, `command`). Use it after plan_clone to see what would degrade; act on one credential with run_auth_flow.
```

### `plan_clone`

- The description's first verb is "return": a word for reading.
- Tag private-data: The input names a repo (input.skipRepo), and the tool reads: it reads repositories.
- 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
Return a read-only plan for a target: compare it against the Workbench profile and list each component as `install`, `present`, or `manual`, with the commands that would run. It still runs a detection probe on the target (same access as inspect_target) but clones nothing and writes nothing. Parameter semantics: `components` restricts the diff to those ids (default: required+core); `workspace` sets the expected profile path on the target (default `~/opencode-workbench`); `profileUrl` overrides the git remote. Use it to preview before apply_clone, which performs the changes.
```
