What is LSP MCP Server?
The LSP MCP Server is a bridge that allows Large Language Models (LLMs) to interact with Language Server Protocol (LSP) interfaces. It enables LLMs to query LSP Hover and Completion providers for more accurate code suggestions.
How to use LSP MCP Server?
The server starts an LSP client, exposes MCP tools to send requests to the LSP server, and returns the results in a format that LLMs can understand. You need to start the LSP server using the start_lsp tool before using other LSP functionalities. Configuration involves specifying the LSP server details and language ID.
