JetBrains IDE MCP Server

npx -y @jetbrains/mcp-proxy

  "mcpServers": {

The server connects an assistant to an open IntelliJ-family IDE, so it sees the file in the editor, applies edits, searches the project and reuses the IDE's own indexes instead of plain text scanning. Since the 2025.2 releases it ships inside the IDEs themselves and the standalone plugin repository is no longer maintained. Clients that only speak stdio connect through a small Node proxy.
