What is the Bifrost MCP Server?

Bifrost is a VS Code extension that creates a Model Context Protocol (MCP) server to expose VSCode's powerful development tools and language features to AI tools. It enables AI coding assistants that support the MCP protocol to implement advanced code navigation, analysis, and operation functions.

How to Use Bifrost?

After installing the extension, Bifrost will automatically start the MCP server. You need to configure your AI assistant to connect to the server endpoint (default port 8008). It supports AI coding assistants such as Cursor and Roo Code.

Applicable Scenarios

When you use an AI coding assistant for code development, refactoring, or analysis, Bifrost can provide more accurate code context and more powerful code navigation functions. It is particularly suitable for large - scale projects or multi - language project development.

Main Features

Language Server Integration
Access VSCode's language server features for any supported language
Code Navigation
Find references, definitions, implementations, etc.
Symbol Search
Search for symbols across the entire workspace
Code Analysis
Get semantic markers, document symbols, and type information
Smart Selection
Perform smart code selection using semantic selection ranges
Multi - Project Support
Configure independent ports and endpoints for each project
Advantages
Expose VSCode's powerful language features to AI tools
Support multiple programming languages (corresponding language extensions need to be installed)
Provide accurate code context and navigation functions
Support multiple projects working simultaneously
Seamlessly integrate with AI assistants such as Cursor and Roo Code
Limitations
Requires VSCode as the running environment
Some language features require additional installation of language extensions
Multi - project configuration requires manual setting of different ports
Initial use requires certain configuration work

How to Use

Install the Extension
Install the Bifrost MCP extension from the VS Code Marketplace
Configure the AI Assistant
Add the corresponding configuration according to the AI assistant you are using (Cursor or Roo Code)
Start the Server
The extension will automatically start the server, or you can manually start it using the command
Multi - Project Configuration (Optional)
Create a bifrost.config.json file in the project root directory to configure the project - specific port

Usage Examples

Find Symbol References
Find all reference locations of a function or variable in the code
Workspace Symbol Search
Search for a specific symbol across the entire workspace
