Bifrost - VSCode Dev Tools MCP Server + Cursor FAQ

Where is the Cursor config file?

Cursor reads MCP servers from ~/.cursor/mcp.json. Paste the Bifrost - VSCode Dev Tools MCP Server config there under the "mcpServers" key and restart the client.

Is Bifrost - VSCode Dev Tools MCP Server safe to use with Cursor?

The server runs as a local HTTP/SSE server (default port 8008) with no authentication; it is intended for local development use. It exposes read and edit capabilities (including rename and code actions) over your codebase to any connected MCP client. Ensure the configured port is only reachable locally.

What port does the server use?

It runs on port 8008 by default. You can change it with a bifrost.config.json file, or per project by specifying a unique port. If the configured port is in use, the server fails to start until it is freed or changed.

How do I connect Cursor or Roo Code?

Add an mcpServers entry pointing to the SSE URL, e.g. {"mcpServers": {"Bifrost": {"url": "http://localhost:8008/sse"}}}.

How do I connect Cline?

Install Supergateway and add an mcpServers config that runs npx supergateway --sse http://localhost:8008/sse. It may appear red but works.
