Best for
  • Developers whose primary assistant is Codex, Cursor, or another non-Claude client and who want an independent Claude opinion
  • Read-only, auditable code-review flows (Read/Glob/Grep access only)
  • Users who want to keep context in one session and ask follow-up questions
  • Engineering teams scaling AI coding agents while controlling spend
  • Platform teams that need auditable, rollback-aware agent execution records
  • Organizations using multiple agents (Claude, Codex, Gemini) under one governed flow
Not for
  • Scenarios where Claude must edit or write to the codebase
  • Users who want one registration covering all providers (Codex, Grok, Gemini, and so on) — use the unified @ask-llm/mcp package from the same repository
  • Users unwilling to install and authenticate the Claude Code CLI
  • Teams needing official Anthropic support or enterprise guarantees
  • Developers who just want a simple code-completion helper without run governance
  • Teams unwilling to accept local JSONL run records with HMAC signing
  • Environments without a supported adapter (Claude/Codex/Gemini CLIs, direct provider, or verifier-only)
Required permissions
  • Runs locally over stdio and invokes the installed, authenticated Claude Code CLI as a subprocess
  • Read-only workspace access limited to Read, Glob, and Grep
  • Reads the configured environment variables (model alias, fallback model, timeout, log level)
  • Sends prompts and relevant file contents to Claude
  • Read/write access to the configured repo root (writable scope restrictable via --allow-path/--deny-path)
  • Ability to invoke the chosen agent CLI (Claude/Codex/Gemini, etc.) and its underlying model account
  • Local disk writes for run records, receipts, and share outputs (share/run-receipt., etc.)
  • Execution of user-configured verifier commands (e.g. npm test)
Risks and side effects
  • Prompts and file contents leave the machine and are processed by Claude, so sensitive code or secrets need care
  • Automatically invokes the Claude Code CLI, which may consume subscription or API quota
  • The default opus model falls back to sonnet when overloaded, so results may come from a different model than expected
  • Third-party, unofficial project with no affiliation with or endorsement by Anthropic
  • Version 0.0.1, so interfaces and behavior may change
  • get-usage-stats is in-memory only; stats are lost when the process restarts
  • Verifier commands are executed; poorly chosen verifier commands carry security risk despite preflight policy checks
  • Cost and token figures may be estimates (labeled with provenance) and should not be treated as settled accounting
  • Receipt integrity must be verified before use as trustworthy evidence; missing rollback evidence is flagged as EVIDENCE_BOUNDARY
  • Policy defaults come from martin.config.yaml and can be overridden by CLI flags; misconfiguration can loosen safety boundaries
