Tree-sitter MCP Server

This MCP server enables coding agents to parse code snippets into Tree-sitter Abstract Syntax Trees (ASTs). It supports a wide variety of programming languages including Python, JavaScript, Rust, and Go. The server provides tools to retrieve syntax tree structures, identifying node kinds, field names, and zero-based row-column ranges, which helps agents understand code structure before generating queries or walking the tree.
