## Findings

- **warn** Annotations that disagree with the tool in `show` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "show" destructive (destructiveHint: true), and its name says "show", a word for reading.

annotations: {"readOnlyHint":false,"destructiveHint":true,"idempotentHint":false,"openWorldHint":true}; The name "show" says "show": a word for reading.
```


## Deletes or cancels (4)

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

### `edit`

- The name "edit" says "edit": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Apply unique exact-text changes atomically as one undoable act (act is its id string), rename with filename, or set Note fields with note. At a moved numeric revision, literal edits apply if untouched since; whole-document replacement needs the current revision. A conflict returns current context; decide afresh. Drawings, painting, Water, comments and HTML objects use fenced text; painting needs an open editor and an operation_id.
```

### `export`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
to:"file" (default) delivers markdown, html (the offline editor), page, txt, docx or pdf; to:"save" saves to the bound destination; to:"clipboard" copies a passage as plain, markdown, formatted or complete. to:"sync" alone syncs the Notes store and can replace files. page, docx and pdf need an editor or renderer. Inspect delivery; export never publishes a website.
```

### `show`

- The name "show" says "show": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it destructive (destructiveHint: true).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Present work or ask the person. An omitted target is inferred from its fields. A 4-letter browser code pairs that editor (target:"pair"); a connected workspace's owner first approves at owner_approval_url, then the person chooses ALLOW. Inspect actual presentation; a request is not proof the person saw it. A comparison leaves source unchanged. Later human navigation wins.
```

### `undo`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Undo one act or one turn (act or turn_id, not both), preserving later work.
```

## Changes things (1)

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

### `open`

- The name "open" says "open": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create {text, filename}, resume {document}, open a Note {document, note}, create one {document, note:"new", text, title} (title only there), or import a host file {file}. Returns revision and whole text when it fits a page; otherwise a document map. A browser code goes to show {target:"pair", code}. Share editor_url when available; keep document private.
```

## Only reads (1)

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

### `read`

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

Description, as the server wrote it:

```untrusted-server-text
Read exact text, a heading/fence map (as:"outline") or a PNG (as:"image") of the page or of the named block, heading or lines. query finds lines here; search lists Notes. Continue next_cursor with cursor alone. Check human context and omissions before editing. state:true reports pending work and the person’s presence; after_revision with wait_ms waits for their next change. guide returns instructions; guide resource URIs are not document IDs.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__rapier__read"
    ],
    "ask": [
      "mcp__rapier__open"
    ],
    "deny": [
      "mcp__rapier__edit",
      "mcp__rapier__undo",
      "mcp__rapier__show",
      "mcp__rapier__export"
    ]
  }
}
```
