Lsp MCP lets Claude, Cursor and other MCP clients work with Lsp MCP directly. MCP server for Language Server Protocol (LSP) integration, providing hover information, code completions, diagnostics, and code actions with resource-based access.
An MCP (Model Context Protocol) server for interacting with LSP (Language Server Protocol) interface. This server acts as a bridge that allows LLMs to query LSP Hover and Completion providers.
The MCP Server works by: 1. Starting an LSP client that connects to a LSP server 2. Exposing MCP tools that send requests to the LSP server 3. Returning the results in a format that LLMs can understand and use
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
