What is MCP?
01
Model Context Protocol is an open standard that lets AI agents connect to external tools and services — databases, APIs, file systems, browsers — without custom integrations.
02
An MCP server exposes a tool's capabilities in a format any AI agent can understand. Claude, GPT, Gemini, and others can discover and use them at runtime.
03
AgentNDX is the curated registry of these servers — hand-picked, quality-scored, and queryable by both humans and agents.
