# Emacs Lisp Development

> Use this tool when you need to analyze and understand Emacs Lisp code, or integrate AI agents with Emacs environments for development and exploration. It provides functionality for code analysis, documentation lookup, and secure source file reading, solving problems such as code comprehension and package development workflows. With inputs including Emacs Lisp code and outputs including function documentation and variable information, it is ideal for use cases involving AI-assisted development, code exploration, and building AI tools that integrate with Emacs internals.

## Description

This MCP server provides Emacs Lisp development assistance through five specialized tools that enable AI agents to interact with Emacs environments for code analysis and documentation lookup. Built by Laurynas Biveinis using TypeScript with the mcp-server-lib foundation, it offers function documentation retrieval, source code definition extraction with header comments, variable information without exposing values, Info documentation lookup from the Emacs Lisp Reference Manual, and secure source file reading from system directories and ELPA packages. The implementation features robust security controls that prevent path traversal attacks, handles both regular and byte-compiled functions, supports dynamic and lexical binding contexts, manages function aliases and C-implemented functions, and provides complete source reconstruction for interactively defined functions, making it valuable for AI-assisted Emacs Lisp development, code exploration and analysis, package development workflows, and building AI tools that need deep integration with Emacs internals.
