## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

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

### `present_pdf`

- The description's first verb is "upload": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Upload a PDF to start a local Presio presentation. Returns a url — open it in a browser to finish handoff (skips share). To replace an existing presentation's deck instead of creating one, pass its session_id plus controller_token (the t= parameter of the url from the original create call) and the same link keeps working. Same as POST /api/present.
```

## Changes things (1)

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

### `plugin_guide`

- 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.

Description, as the server wrote it:

```untrusted-server-text
The guide to building a Presio plugin: the workflow (a presio-<name> GitHub repo from the template, the checker, a tag, and a ?plugins= link that loads it), the manifest, and the full window.presio API. Read it before writing a plugin. Same as GET /plugins.md.
```

## Only reads (1)

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

### `check_pdf`

- The description's first verb is "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Validate Presio notes/media sidecar attachments in a PDF. Same as POST /api/check.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__presio__check_pdf"
    ],
    "ask": [
      "mcp__presio__plugin_guide"
    ],
    "deny": [
      "mcp__presio__present_pdf"
    ]
  }
}
```
