Documentation

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

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).

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

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

Tool	Description
`list_projects`	List all projects in the workspace
`list_launch_configs`	List all run/debug configurations
`list_launches`	List active and recent launches
`launch`	Launch a run configuration (run or debug mode)
`terminate`	Terminate running launches
`refresh_project`	Refresh project(s) from filesystem
`build_project`	Build project(s)
`get_console_output`	Read stdout/stderr from a launch
`run`	All-in-one: terminate + refresh + build + launch

Requires Java 17+ and Eclipse IDE (2023-06 or later).

cd plugin
build-plugin.bat

This compiles, builds the JAR, and copies it to your Eclipse dropins/ directory.
