# A2A Protocol (Agent-to-Agent)

Google's open protocol for communication between AI agents across different vendors and platforms. Complementary to MCP (which connects agents to tools/data); A2A handles agent-to-agent task delegation. Mentioned alongside [Agent-Native](https://vietbui.mintlify.site/entities/agent-native.md) as one of the communication surfaces its shared action vocabulary supports.
