What it does

The server gives an MCP client a set of tools to read and write Altium Designer libraries in the binary .PcbLib and .SchLib formats. The agent reasons about footprint or symbol geometry, and the server assembles a valid file that Altium opens without errors. It covers primitive creation, pad placement and standard board layers. It runs as a local stdio server from a prebuilt binary, a Claude Desktop extension or a Docker container.

Who it is for. For hardware engineers who maintain component libraries in Altium Designer and work through an MCP client.

Example request

Build an Altium footprint for this QFN package from the datasheet and add a symbol to the library

Limitations

The server handles only Altium library formats (.PcbLib and .SchLib), and the result still needs a check in Altium itself. Prebuilt binaries are unsigned, so SmartScreen and Gatekeeper warn on first run; the authors suggest verifying the build via SLSA attestation. GPL-3.0 licensed.

How to disable. Remove the server from the MCP client configuration or uninstall the Claude Desktop extension, then delete the downloaded binary or Docker image.

Security check

• The server reads and writes files in the mounted library folder
• It runs a local binary or container

README in short

The README explains that building an Altium library by hand is slow, and asking an agent to emit the binary file directly yields a corrupt file. The server takes over the writing: the agent sets the geometry, the server assembles valid .PcbLib and .SchLib files. It documents standard board layers, install options via a prebuilt binary, a .mcpb Claude Desktop extension and Docker, plus download verification through SLSA attestation. It works with any stdio MCP client.
