Altium Designer MCP server

This is a helper that lets your AI assistant create and change Altium Designer component libraries. It works with the .PcbLib files that hold footprints and the .SchLib files that hold symbols. It is handy if you build or look after Altium parts libraries and want the AI to do the slow, repetitive parts.

What this MCP server does

You tell your AI what part you want, such as a 0603 resistor or a new connector. The AI works out the pad sizes, courtyards and silkscreen using standard rules, then asks this helper to write the footprint and symbol into your library files. The helper reads and writes the actual Altium files, places the pads and shapes, and can attach 3D STEP models. When it is done, you get a real library file that Altium can open, plus a short summary in the chat.

What you can do with it

• Create new footprints and symbols from a description
• Read and list what is already inside a library
• Update a pad, a shape or a whole component in place
• Compare two libraries or two components to spot differences
• Copy, rename, merge or delete components
• Validate a library and clean up leftover data
• Export a library to JSON or CSV, and import it back

Try asking your AI

• “Create a 0603 resistor footprint and symbol in my library”
• “List all the components in my PcbLib file”
• “Change pad 1 of the SOIC-8 footprint to a rectangle”
• “Compare these two libraries and tell me what changed”

What it gives back to you

You get plain answers in the chat, like a list of component names, a summary of what was written, or a short preview of a footprint drawn as text. It can also hand back exported files in JSON or CSV, and it can pull out embedded STEP 3D models. When it changes something, it tells you what it changed.
