LSP MCP Server puts a Language Server Protocol client between an MCP client and a real language server, so a model can ask the same questions an editor asks. It starts the language server, keeps the LSP session alive, and translates MCP tool calls into LSP requests. The tools cover hover information at a file position, completion suggestions at a position, code actions for a range, opening and closing documents in the language server, and retrieving diagnostics such as errors and warnings for open files. Operational tools start the language server against a root directory, restart it without restarting the MCP server, and change log verbosity at runtime. Diagnostics are also published as MCP resources under an lsp-diagnostics:// scheme with subscription support, so a client receives updates as the language server revises them rather than having to poll. Configuration is a single stdio command taking the language id, the path to the language server binary and any arguments it needs, which makes the server language-agnostic — the same package fronts a Haskell, TypeScript or Rust language server depending on what it is pointed at. The stated purpose is accuracy: rather than inferring an API from surrounding text, the model reads the types, symbols and errors the compiler itself reports. The audience is developers using agents for code editing who want the agent grounded in real type information.
