MACP: the Multi-Agent Cognition Protocol – real-time coordination for AI agents

Summary: MACP is a protocol enabling live coordination between multiple AI agents by providing shared ownership, real-time updates, and priority-ranked signals during execution. It uses a lightweight SQLite-backed message bus with durable delivery and integrates via a TypeScript core and MCP server to keep agents aligned and prevent conflicts.

What it does

MACP facilitates real-time communication and coordination among autonomous AI agents through a shared message bus that supports durable, prioritized signals, allowing agents to signal ownership and share updates while work is ongoing.

Who it's for

It is designed for developers building multi-agent systems, autonomous AI agents, and orchestration tools requiring synchronized, real-time interaction.

Why it matters

MACP addresses the limitations of orchestration by enabling agents to coordinate dynamically and avoid collisions during parallel execution.
