MCPxHub
A local MCP middleware layer that helps Claude Desktop connect to VS Code-family and JetBrains IDEs.
MCPxHub sits between Claude Desktop and MCP-enabled IDE plugins. Instead of editing every client config when an IDE port changes, the hub scans expected local port ranges, finds an active VS Code-family or JetBrains server, and forwards MCP JSON-RPC calls to the right place.
Use it when your coding assistant should attach to whichever supported IDE is currently running. It is a local proxy: the IDE plugin still owns file, terminal, and code tools; MCPxHub focuses on discovery, routing, reconnection, and keeping the Claude Desktop configuration small.
Local MCP routing layer
Local MCP proxy
Forwards MCP JSON-RPC calls between Claude Desktop and the active IDE plugin.
Smart IDE discovery
Scans standard local port ranges for VS Code-family and JetBrains MCP servers.
Resilient connection
Adaptive polling keeps waiting for the IDE and reconnects after restarts.
Editor compatibility
Works with VS Code, Cursor, Windsurf, Antigravity, and JetBrains IDEs when their MCP server plugins are installed.
