Changes things 1Claude Code: ask
  • faf_scoreScore a .faf — 0-100 completeness (Rust→WASM, at the edge).No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Score a .faf — 0-100 completeness (Rust→WASM, at the edge).
Only reads 2Claude Code: allow
  • faf_readParse a .faf and return its normalized structure (Rust→WASM, at the edge).No findings

    Why it is in this group

    • The name "faf_read" says "read": a word for reading.
    Description, as the server wrote it
    Parse a .faf and return its normalized structure (Rust→WASM, at the edge).
  • faf_validateValidate a .faf and return completeness score + errors/warnings (Rust→WASM, at the edge).No findings

    Why it is in this group

    • The name "faf_validate" says "validate": a word for reading.
    Description, as the server wrote it
    Validate a .faf and return completeness score + errors/warnings (Rust→WASM, at the edge).

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Claude Code permissions

Allow the reads, ask before a change, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__rust-faf__faf_validate",
      "mcp__rust-faf__faf_read"
    ],
    "ask": [
      "mcp__rust-faf__faf_score"
    ],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as rust-faf. Review it before you use it.
