Best for
  • Engineers designing PCBs with KiCad 9.0+
  • Users who want natural-language access to design data in Claude Desktop or other MCP clients
  • Teams working across macOS, Windows, and Linux
  • 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
  • Users not on KiCad or on versions below 9.0
  • Users without Python 3.10+ and uv
  • Users expecting a one-click install with no local configuration
  • 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
  • Read local KiCad project directories defined via KICAD_SEARCH_PATHS and related environment variables
  • Read KiCad project, schematic, and PCB files
  • Invoke the KiCad CLI for operations such as DRC
  • Launch the KiCad application
  • Generate visualizations and export files such as BOMs
  • 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
  • The server reads local design files; overly broad search paths may expose unrelated files
  • Some tools have side effects (opening apps, generating files) and should be invoked with user approval
  • Community-maintained software may contain bugs or lag behind new KiCad releases
  • Client configuration requires absolute paths or the server may fail due to undefined working directories
  • 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
