# easyeda-pro-mcp

Wires an AI client into the EasyEDA Pro project you have open, so the agent reads components and nets instead of squinting at screenshots. Handy for picking apart someone else's board.

## What it does

The server sits between your MCP client and the editor. Requests travel from the client to a local Node.js server, then over a WebSocket bridge into an extension running inside EasyEDA Pro. Nothing gets exported by hand: the agent works with the live document.

You can pull the schematic apart piece by piece — components, pins, nets, wires and labels. Other tools trace a part or a net, check that the connections you expect actually exist, and help you move around the editor. Anything that changes the project waits for your confirmation.

It needs Node.js 20 or newer, EasyEDA Pro running with the extension installed, and external interaction permission switched on. The bridge binds to `127.0.0.1` by default; keep that port off untrusted networks. Offline `.epro` parsing and order operations are not part of it, so with the editor closed the server has nothing to read.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `EASYEDA_MCP_WS_HOST`, `EASYEDA_MCP_WS_PORT` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- find which nets a component sits on in the open schematic
- verify expected connections and catch mismatches
- pull components, nets and warnings in a single request
- jump to a specific part in the editor on the agent's hint
- confirm the client-to-editor bridge is actually alive

## Example prompts
- Run `easyeda_doctor` and tell me whether the EasyEDA Pro bridge is healthy.
- Call `easyeda_get_context` and name the document that is currently open.
- Trace USB1 with `easyeda_trace_component` and list the nets it touches.
