MCP Lsp Bridge, developed by Rockerboo, is an MCP server tool designed to integrate Language Server Protocol (LSP) servers with Model Context Protocol (MCP)-compatible agents. Built with Go, this free program allows AI agents to access advanced code intelligence and refactoring features. It extends the functionality of agents like Claude Code by exposing capabilities such as finding definitions, tracing references, and formatting code. Distribution is handled through downloadable binaries or building from source, making it accessible for developers seeking enhanced code interaction for their AI tools.

What does MCP Lsp Bridge connect to?

MCP Lsp Bridge acts as a crucial link between Language Server Protocol (LSP) servers and Model Context Protocol (MCP)-compatible agents. Its primary function is to expose the advanced capabilities of various LSP servers to these agents, effectively bridging the communication gap. This connection allows MCP agents to interact with code in a more sophisticated manner, drawing upon the rich features provided by LSP servers for development tasks.

Core features and tools

The official documentation for MCP Lsp Bridge highlights its exposed capabilities rather than specific callable tool names. These include Code Intelligence, offering functions like getting documentation, finding definitions, tracing references, and identifying errors. It also provides Safe Refactoring, enabling renaming symbols, formatting code, and applying quick fixes with a preview mode. Additionally, Project Analysis features allow searching across codebases, understanding project structure, and detecting programming languages.

Who is it for?

MCP Lsp Bridge is intended for developers and users of MCP-compatible AI agents, such as Claude Code, who require advanced code intelligence features. It enhances the ability of these agents to understand, analyze, and modify code effectively. The program is particularly useful for those integrating AI into their development workflows for tasks requiring precise code interaction. Skip this if you do not use MCP-compatible AI agents or do not require enhanced code intelligence for them.

How to get started

No credentials are required. Setup involves configuring the MCP client to use "mcp-lsp-bridge" as an MCP server with "type: "stdio"" and providing an "lsp_config.json" file.

Use cases

• Obtaining code intelligence, including documentation, definitions, references, and error identification.
• Performing safe refactoring operations such as renaming symbols, formatting code, and applying quick fixes.
• Conducting project analysis, which involves searching across codebases and understanding project structure.

MCP Lsp Bridge by Rockerboo offers a valuable connection for MCP-compatible AI agents to access LSP server capabilities. It empowers agents with advanced code intelligence, safe refactoring, and project analysis features, enhancing their utility in development workflows. This free tool, built in Go, supports the stdio transport protocol and integrates with agents like Claude Code.
