NPM Package Github Repo

About

Proxy Sidecar extends the JetBrains MCP Server by adding real-time WebSocket monitoring capabilities. This allows developers and users to observe all MCP tool calls, including endpoint and arguments, as they occur. It acts as a proxy between MCP clients and a JetBrains IDE, forwarding commands while simultaneously broadcasting tool call information via WebSocket. This is useful for debugging, monitoring, and understanding how MCP clients interact with the IDE.

Key Features

  • Real-time WebSocket monitoring of MCP tool calls
  • Detailed information about endpoint and arguments for each tool call
  • Compatible with existing JetBrains MCP Server features
  • Easy integration with Claude Desktop
  • Configurable WebSocket port

Use Cases

  • Debugging MCP client integrations
  • Monitoring tool usage for analysis and optimization
  • Observing interactions between MCP clients and JetBrains IDEs
