## Only reads (1)

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

### `find_common_ground`

- The name "find_common_ground" says "find": a word for reading.
- 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
Pick ONE movie, TV show, book, music artist, podcast, restaurant (kind=place, with location) or destination that a whole group will enjoy. Give each person's name and 2 to 5 things they love. Favourites can come from another category with tasteFrom, for example music artists to pick a restaurant, or any for a mix of artists, movies, TV shows and books. Uses Qloo's taste graph to score every candidate for every person and returns the option that makes the least happy person as happy as possible, with a reason per person.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `common-ground`:

```json

  "permissions": {
    "allow": [
      "mcp__common-ground__find_common_ground"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__common-ground__find_common_ground`: untrusted-input
