Model Context Protocol
MCP StableStewarded by Anthropic
01 / What it is
A JSON-RPC protocol between a model host and servers that expose tools, resources and prompts. A host connects to any number of servers over stdio or HTTP and lets the model call what they publish.
Tool-side: how an agent reaches capabilities. A2A is how agents reach each other.
