KiCAD-MCP-Server
KiCAD-MCP-Server is an MCP (Model Context Protocol) server implemented in Python that lets AI assistants control KiCad for PCB design automation. It exposes a large set of MCP tools for schematic creation/wiring, PCB/board operations, routing, exports, and project state resources, with dynamic discovery and schema validation.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
No authentication/authorization model is described, so access control likely relies on local network/desktop integration assumptions. HTTPS/TLS requirements are not stated (TLS not applicable for local MCP in many deployments). README includes a privacy warning about session logs containing tool call history and file paths when DEV mode is enabled—this is a notable data-leak risk if logs are shared.
⚡ Reliability
Best When
Used locally or in a controlled environment where an MCP client (e.g., Claude Desktop) can safely operate a KiCad workspace and where AI-driven iteration speeds up PCB/schematic generation.
Avoid When
Avoid exposing it as a network-accessible service to untrusted users/agents without strong operational isolation, because it can modify local project files and uses experimental UI synchronization backends.
Use Cases
- • AI-assisted schematic drafting (component placement, pin discovery, wiring, net labels)
- • AI-assisted PCB board setup (board outline, layers, mounting holes, zones)
- • AI-assisted routing (trace/via routing, pad-to-pad routing, differential pairs)
- • Project inspection and state retrieval for iterative design workflows
- • Export automation (e.g., Gerber/snapshots) and design checkpointing
- • Integration with external parts catalogs (JLCPCB) for component selection
Not For
- • Security-sensitive remote usage without appropriate sandboxing and access controls
- • High-assurance design verification where independent EDA checks are required
- • Environments that require OAuth-style centralized auth or strict enterprise policy enforcement
Interface
Authentication
No auth mechanism (API keys/OAuth) is described in the provided README content; MCP clients typically connect via local desktop integration. This evaluation therefore assumes authentication/authorization is not a primary concern in the documented interface.
Pricing
Open-source tooling; no pricing information provided.
Agent Metadata
Known Gotchas
- ⚠ Tools likely mutate KiCad project state; agents should use project snapshots and/or perform checks before re-running.
- ⚠ Dynamic symbol loading and IPC backend are mentioned as complex/experimental areas; behavior may vary by KiCad version and environment.
- ⚠ Session logs (when DEV mode is enabled) can contain sensitive file paths/design details.
