Best for
  • Developers and teams building AI agents that need extra oversight to prevent reasoning lock-in and over-engineering.
  • Users working with MCP clients like Claude Desktop, Cursor, Windsurf, or VS Code who want long-horizon workflows to stay on track.
  • Developers seeking research-backed reliability improvements for agents.
  • 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
  • Simple or fast tasks where an external oversight call adds unwanted latency and cost.
  • Scenarios where you cannot or do not want to rely on external LLM API calls (requires at least one provider key).
  • Projects requiring active feature development or official support, as the server is in maintenance mode.
  • 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
  • Requires at least one LLM provider API key (Gemini, OpenAI, OpenRouter, or Anthropic) to function.
  • HTTP mode opens a network port; recommend restricting to loopback for security.
  • May modify client configuration files (e.g., Claude Desktop, Cursor, Windsurf, VS Code) during installation to add the server entry.
  • 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
  • Sending prompts and context to external LLM APIs; ensure sensitive data is not exposed.
  • HTTP mode with non-loopback access increases attack surface; v2.9.0 adds host validation and CORS restrictions but misconfiguration could cause outages.
  • Over-frequent `vibe_check` calls can slow down agent execution and increase costs; optimal dose is ~10-20% of steps.
  • 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
