Two questions: 'What can I offer?' (capability announcement) and 'What do I need?' (task-driven discovery).

MCP: JSON-RPC tools/list. A2A: Agent Cards at /.well-known/agent.json. ATProtocol: Lexicons as capability schemas.

Semantic matching: MCP-RAG achieves 99.6% token reduction, 97.1% hit rate at top 3. Embedding-based discovery.

A2A has 150+ orgs supporting (Google, Salesforce, SAP, Atlassian, MongoDB, LangChain).
