Nexus MCP Bridge for VSCode

What is Nexus MCP Bridge for VSCode?

It is designed for users who want Claude Desktop to interact directly with workspace files and directories while keeping a small memory footprint and staying inside VSCode.

How to use Nexus MCP Bridge for VSCode?

Install the extension from the VSIX file, then optionally configure settings such as the port and allowed paths. The bridge can start automatically on VSCode launch (startOnLaunch setting) or manually via the commands: “Start Nexus MCP Bridge”, “Stop Nexus MCP Bridge”, or “Toggle Nexus MCP Bridge” from the status bar. Finally, add the bridge to Claude Desktop’s claude_desktop_config.json with the URL http://localhost:3000/mcp and list the tools you want to allow.
