Bridge LLMs and LSPs with LSP-MCP Server
Experience seamless integration between language models and Language Server Protocols. Enhance code intelligence, diagnostics, and completions for your AI workflows with LSP-MCP.
What is LSP MCP Server
The LSP MCP Server, developed by Tritlo, is an advanced Model Context Protocol (MCP) server that bridges Language Server Protocol (LSP) features with large language models (LLMs) and AI agents. This server enables LLMs to interact programmatically with LSPs, providing access to essential code intelligence features such as hover information, code completions, diagnostics, and code actions. By starting an LSP client and exposing these capabilities through the MCP interface, the server allows AI systems to query and consume rich programming insights from any compatible language server. The LSP MCP Server supports a robust logging system, real-time diagnostics subscriptions, and flexible configuration, making it a critical backend tool for AI-powered code assistance, code review, and developer tooling automation.
Capabilities
What we can do with LSP MCP Server
The LSP MCP Server enables developers and AI systems to tap into the advanced capabilities of Language Server Protocols in a programmatic and automated way. Here are some of the core things you can do with the service:
- Get hover information
- Retrieve detailed type hints, documentation, and symbol details at any location in a source file.
- Get code completions
- Receive intelligent code completion suggestions based on the programming context.
- Get diagnostics
- Access real-time error and warning messages from the language server for open files.
- Get code actions
- Query for automated code fixes and refactorings for specific code ranges.
- Open/close documents
- Programmatically open or close files for analysis, managing resources efficiently.
How AI Agents Benefit from LSP MCP Server
AI agents can leverage the LSP MCP Server to provide smarter code understanding, error detection, and code generation capabilities. By programmatically querying LSPs through the MCP interface, agents can fetch hover info, completions, diagnostics, and code actions in real time. This allows them to deliver highly contextual code suggestions, identify bugs, and automate refactoring tasks—significantly enhancing their effectiveness as programming assistants or autonomous software engineers.
