Best for
  • Full-stack developers building generative UI quickly
  • Teams wanting to deploy the same agent across web, mobile, and Slack
  • Projects using React, Angular, Vue, or React Native
  • 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 requiring persistent agent state (needs extra setup)
  • Projects needing only simple chatbots without generative UI
  • Projects not using a frontend framework
  • 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 an LLM API key (e.g., OpenAI, Anthropic, Gemini)
  • May need network access to connect to agent services
  • 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
  • As an MCP server, there may be a mismatch since CopilotKit is an SDK, not a native MCP server; tools may not be directly exposed.
  • Dependency on external LLM services may incur costs.
  • Generative UI may introduce security risks; user input must be handled carefully.
  • 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
