The LSP MCP Server is a Model Context Protocol server designed for interacting with the Language Server Protocol interface. This server acts as a bridge, enabling large language models (LLMs) to query LSP hover and completion providers. By doing so, LLMs can obtain more accurate code suggestions, enhancing their utility in code development and analysis.
