Setup
- Install the extension from the VS Code marketplace: ConnorHallman.bifrost-mcp.
- Install any language-specific extensions you need.
- Open your project in VS Code; the extension will automatically start an MCP server.
- Configure your AI assistant to connect to the SSE endpoint (default http://localhost:8008/sse).
Fit and risk
Not for
- Users without AI integration or simple text editing needs.
- Users preferring a terminal-only MCP server without VS Code.
Required permissions
- Listen on a local HTTP port for requests.
- Read code file contents.
- Execute code operations like symbol search and rename.
Risks and side effects
- Local server lacks authentication, potentially exposing sensitive code to malicious processes.
- Port conflicts or occupation may cause service unavailability.
- AI-initiated renames could break the codebase if not reviewed.
Troubleshooting
- Ensure appropriate language extensions are installed.
- Check that your project is loaded correctly in VS Code.
- Verify that port 8008 is available.
- Check the VS Code output panel for error messages.
