## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `engagement_path`

- 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
How to start a Block 0 brief. This tool does not book or charge.
```

## Only reads (2)

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

### `get_source_of_truth`

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

Description, as the server wrote it:

```untrusted-server-text
Operating layers for the public NTWX Studio catalogue at studio.ml-nightworx.io.
```

### `list_products`

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

Description, as the server wrote it:

```untrusted-server-text
Four intelligence products with indicative AUD figures. Not a quote.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__catalogue__get_source_of_truth",
      "mcp__catalogue__list_products"
    ],
    "ask": [
      "mcp__catalogue__engagement_path"
    ],
    "deny": []
  }
}
```
