Model Context Protocol (MCP) is one of 15 APIs that [Agent Readiness](https://apis.io/providers/agent-readiness/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Agent Tooling, Agent Readiness, JSON-RPC, and Standards. The published artifact set on APIs.io includes API documentation and a GitHub repository.

An open JSON-RPC protocol that lets AI agents talk to tools, resources, and prompts through a uniform server surface. MCP is the most direct expression of "an API designed for an agent" — every API surface that ships an MCP server scores higher on agent readiness because agents can call it through one shared transport.
