## Changes things (2)

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

### `check_vendor`

- 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.

      "mcp__agentum-entity-resolver__check_vendor"
    ],
