Model Context Protocol
Open standard for connecting AI to tools and data
The Model Context Protocol, or MCP, is an open standard that lets AI applications connect to outside tools and data in one consistent way. Instead of building a separate integration for each app, a tool author builds an MCP server once, and any compatible AI app can use it.
This site lists many MCP servers and related tools. The protocol itself comes with a specification, documentation and software development kits in several languages, so developers can build their own servers and clients.
