What is the Model Context Protocol (MCP)?
The Model Context Protocol (MCP) is an open standard that lets AI coding agents like Claude Code, Cursor, and Codex connect to external tools, data, and actions through one uniform interface. Instead of bespoke integrations, an agent speaks a single protocol to any MCP server and calls its tools live - the plumbing behind every "MCP server."
Skillselion catalogs 9,891 MCP servers, ranked by GitHub stars because MCP servers do not report comparable install counts.
