How MCP Standardizes Agent-to-Tool Communication
modelcontextprotocol.io/introduction
Summary
The Model Context Protocol is an open standard by Anthropic that defines how AI agents connect to external data sources and tools using a JSON-RPC transport layer. MCP separates the concern of agent-to-tool communication from the knowledge schema those tools serve, enabling any MCP server to expose structured, predictable payloads to any compatible agent.
