MCP and A2A protocols integrate for agent tool use and coordination

By PulseAugur Editorial · [1 sources] ·

The MCP and A2A protocols are designed to work together, addressing different aspects of agent functionality. MCP focuses on enabling agents to access external resources like files, APIs, and databases, acting as a tool belt. A2A, on the other hand, handles agent-to-agent coordination and task delegation, serving as an interoperability protocol. While A2A has gained broad industry adoption with major companies like AWS and Microsoft joining the Linux Foundation, OpenAI has not yet integrated A2A support into its Python SDK, necessitating workarounds for cross-framework interoperability.
