Agentic AI Foundation builds MCP, A2A and Goose standards stack for AI agents

The Agentic AI Foundation is developing a standards stack for cross-vendor AI agents: MCP standardizes tool discovery and invocation, A2A handles authentication, message routing and state synchronization between agents, and Goose serves as a reference implementation and conformance test harness.

• MCP defines a JSON-RPC 2.0 transport and schema registry for tool discovery and invocation
• A2A covers mTLS or OAuth 2.0, task routing and shared state across agent boundaries
• Goose is a working agent runtime and conformance suite for interoperability testing
• The stack sits below orchestrators like LangGraph and Temporal rather than replacing them
