MDX MCP Server
Universal MCP server for intelligent MDX file processing and analysis
Overview
MDX MCP Server is a powerful Model Context Protocol server that enables LLMs to seamlessly interact with, search, and process MDX files. It provides robust tools for reading MDX content as clean Markdown, performing contextual searches, converting files, and extracting metadata, all with built-in cross-platform compatibility and security.
Core Features
| Feature | Description |
|---|---|
| MDX Reading | Convert MDX to clean Markdown format on the fly |
| Contextual Search | Find content within MDX files with surrounding context |
| Format Conversion | Convert and save MDX files to standard Markdown |
| Metadata Extraction | Parse and retrieve YAML frontmatter |
| Cross-Platform | Native support for Windows, Linux, and macOS |
| Path Safety | Secure path resolution preventing directory traversal |
