hechtcarmel/jetbrains-index-mcp-plugin

A JetBrains IDE plugin that exposes an **MCP (Model Context Protocol) server**, enabling AI coding assistants like Claude, Codex, Cursor, and Windsurf to leverage the IDE's powerful indexing and refactoring capabilities.
**Fully tested**: IntelliJ IDEA, PyCharm, WebStorm, GoLand, RustRover, Android Studio, PhpStorm
**May work** (untested): RubyMine, CLion, DataGrip
**Not supported**: Rider (its ReSharper backend does not expose the IntelliJ PSI APIs this plugin relies on; see #167)
**IDE Index MCP Server** provides AI coding assistants with access to the IDE's powerful code intelligence features through the Model Context Protocol (MCP).
