KiCad MCP servers: which one to use
All KiCad MCP servers are community projects. Use KiCad MCP Pro to review a design read-only, or KiCAD MCP Server for 247 tools.

- runs on your machine
These are community servers, and each one needs KiCad installed on your computer. KiCad MCP Pro starts in a read-only review profile, so it is the safest first pick. KiCAD MCP Server by mixelpixx has the most GitHub stars on this page (about 3,100) and registers 247 tools. Edits change your project files, so work on a copy or keep the project in git.
Good for
- PCB designers who want Claude to run ERC and DRC checks and explain the errors
- Hobbyists who want a schematic drafted from a plain description
- Engineers preparing a board for manufacturing who want a second pair of eyes
- Anyone who wants an assistant to look at a design without changing it
Which KiCad MCP server to use
Use KiCad MCP Pro to review a design without changing it, and KiCAD MCP Server when you want 247 tools. Pick KiCad Copilot for hierarchical schematics. mcp-server-kicad is in maintenance mode, and its README suggests Claude Code with kicad-cli instead.

Questions
Is there an official KiCad MCP server?
All the servers on this page are community projects, not made by the KiCad team. Each one runs on your own computer next to a KiCad install.
Which KiCad MCP server is the most used?
KiCAD MCP Server by mixelpixx, with about 3,100 GitHub stars. The next is lamaalrajih's kicad-mcp with about 530, last updated in October 2025, then Seeed's KiCad MCP Server (about 180) and KiCad MCP Pro (about 170). The KiCAD MCP Server README says the author now builds new work in a Rust rewrite called Konnect, and that this Python server stays open and maintained.
Is there a read-only KiCad MCP server?
KiCad MCP Pro starts in a read-only review mode. Its default profile has review tools only, and you switch to a build profile with write mode when you want edits. The other servers on this page edit your project files.
Does a KiCad MCP server work in Claude?
Yes. The KiCAD MCP Server README covers Claude Desktop and Claude Code, and KiCad Copilot's README gives a Claude Code command. The blwfish kicad-mcp README recommends Claude Opus with subagents.
Does a KiCad MCP server work in Cursor?
Yes. The blwfish kicad-mcp README says Claude Code, Cursor and Gemini are supported, and says it has 18 tools, which is well within client limits.
What do I need installed first?
KiCad itself. KiCad Copilot and mcp-server-kicad support KiCad 9 and 10. The KiCAD MCP Server runs on Linux, Windows and macOS and uses KiCad's own Python.
Why does the KiCAD MCP Server have so many tools?
It registers 247 tools, and some clients cap the count. Set KICAD_MCP_TOOLBOXES=core to start with 37 tools. The README says VS Code Copilot stops at 128 tools.
Is mcp-server-kicad still maintained?
It is in maintenance mode as of October 2026, with security and KiCad compatibility fixes only. Its README says plain Claude Code with kicad-cli got 18 of 18 small edits right, against 3 of 18 with the plugin, and suggests using Claude Code with kicad-cli instead.
Is it safe to let AI edit my board files?
Edits change your project files on disk. Work on a copy or keep the project in git so you can undo a bad change, and run KiCad's own ERC and DRC afterwards. KiCad MCP Pro's README says its signal and thermal estimates are first-pass and not a sign-off.
Are the KiCad MCP servers free?
Yes. KiCAD MCP Server, KiCad MCP Pro, KiCad Copilot, kicad-mcp (both blwfish and lamaalrajih) are MIT licensed, and mcp-server-kicad is GPL-3.0. Konnect, the Rust successor to the KiCAD MCP Server, is AGPL-3.0 with paid licenses for businesses.
