Blog MCP Server

An MCP (Model Context Protocol) server that lets AI clients interact with blog engines supporting classic XML-RPC blogging APIs.

Supported APIs

• MetaWeblog — post CRUD, categories, media upload
• Blogger — post CRUD, user info, blog listing
• Movable Type — category management, post titles, extends MetaWeblog/Blogger

Auto-Discovery

Point the discover_blog tool at any blog URL and it will fetch the RSD document to detect which APIs are available and where the XML-RPC endpoint lives.
