## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `faf_score`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Score a .faf — 0-100 completeness (Rust→WASM, at the edge).
```

## Only reads (2)

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

### `faf_read`

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

Description, as the server wrote it:

```untrusted-server-text
Parse a .faf and return its normalized structure (Rust→WASM, at the edge).
```

### `faf_validate`

- The name "faf_validate" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Validate a .faf and return completeness score + errors/warnings (Rust→WASM, at the edge).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__rust-faf__faf_validate",
      "mcp__rust-faf__faf_read"
    ],
    "ask": [
      "mcp__rust-faf__faf_score"
    ],
    "deny": []
  }
}
```
