# Pathfinder

> Use this tool when you need to integrate Language Server Protocol (LSP) features into your development workflow, enabling AI assistants to access features like jump-to-definition and code navigation across multiple programming languages. It solves problems related to code understanding, symbol lookup, and code relationships by bridging MCP clients to LSP servers. Pathfinder takes in file extensions and outputs LSP functionality, making it ideal for use cases involving code development and navigation in various programming languages.

## Description

Pathfinder bridges MCP clients to Language Server Protocol (LSP) servers, enabling AI assistants to access jump-to-definition and other LSP features across multiple programming languages. Built in Rust, it spawns and manages individual LSP server processes (like rust-analyzer, pyright, or typescript-language-server), handles the JSON-RPC communication protocol, and exposes LSP functionality through MCP tools with automatic retry logic for indexing delays. Each pathfinder instance manages one LSP server and supports multiple file extensions, making it useful for code navigation, symbol lookup, and understanding code relationships in development workflows.
