Eclipse MCP Server

An Eclipse IDE plugin that lets Claude Code control your Eclipse workspace — build, launch, read console output, and more.

Quick Start

1. Download and install

Download eclipse.mcp.server_0.3.0.jar from the latest release and copy it into your Eclipse dropins/ folder:

<eclipse-install-dir>/eclipse/dropins/

Restart Eclipse (use -clean on first install).

2. Connect Claude Code

claude mcp add eclipse --transport http http://localhost:5188/mcp -s user

That's it. Claude Code can now control your Eclipse workspace.
