Easyeda Pro MCP

What easyeda-pro-mcp does

easyeda-pro-mcp links an MCP-compatible AI client with a live project in EasyEDA Pro. Its companion extension runs inside the editor and provides the connection to the MCP server, allowing an agent to work with structured schematic and PCB data rather than screenshots or manually exported files.

The server supports read-oriented design inspection, including schematic and PCB snapshots, component and pin information, net tracing, and checks for unconnected pins. It also supports programmatic assertions for common circuit requirements such as pull-up or pull-down arrangements, decoupling capacitors, and USB-C 5.1k CC paths.

For PCB work, agents can read active design rules, saved profiles, and net or region tables. Proposed rule changes can be previewed before confirmed updates are applied, followed by readback verification. Editor navigation can focus components or regions, and the integration can export BOM, netlist, Gerber, and PDF files.

How it works

The integration has two local pieces: the @vlabsoftware/easyeda-pro-mcp MCP process launched by the AI client, and the easyeda_mcp_bridge.eext extension installed in EasyEDA Pro. Communication uses MCP over local stdio, with the bridge available through ws://127.0.0.1:8765.

EasyEDA Pro must have the relevant schematic or PCB project open. After installing or enabling the extension, the bridge can reconnect from the EasyEDA Pro toolbar when necessary. A diagnostic tool named easyeda_doctor can check bridge health; easyeda_schematic_snapshot inspects the open schematic, and easyeda_verify_connection supports connection verification workflows.

Setup and configuration

Node.js 20 or newer and EasyEDA Pro 2.3.0 or newer are required. The quickest setup is:

npx -y @vlabsoftware/easyeda-pro-mcp setup

This configures detected clients and places the EasyEDA extension package in the Downloads folder or the current directory. Install that .eext package through EasyEDA Pro’s Extensions Manager, enable “Allow interactive with external” for the bridge, and open the target project.

The MCP server can also be added manually with a standard stdio configuration:

{
  "mcpServers": {
    "easyeda-pro": {
      "command": "npx",
      "args": ["-y", "@vlabsoftware/easyeda-pro-mcp"]
    }
  }
}

On Windows GUI clients, use cmd with /c before the npx arguments. The setup command also supports client-specific configuration for detected installations. Building from source uses npm install, npm run setup:local, and optionally npm run setup:clients.

Limitations and notes

The workflow depends on EasyEDA Pro being installed, the bridge extension being enabled, and a project being open in the editor. The server is designed for local use rather than a remote hosted connection. Inspection is read-only by default; actions that change the project or design rules require explicit human confirmation. Supported platforms are Windows, macOS, and Linux. The project is released under the MIT license.
