agntcy-mcp-server

MCP bridge for the AGNTCY multi-agent network — agent registry, ACP messaging, SLIM protocol, and capability discovery.

What is AGNTCY?

AGNTCY (Agent Network for Generative and Cognitive Yield) is a Linux Foundation initiative with 65+ enterprise partners (Cisco, Dell, Google, Oracle, Red Hat) for standardized multi-agent communication.

Key protocols:

• ACP (Agent Communication Protocol v1.14): Standard message format for agent-to-agent communication
• SLIM (Secure Low-latency Interactive Messaging): Secure real-time communication with pub-sub and encryption
• AGNTCY Directory: Service registry for agent discovery

Features (7 Tools)

      "command": "agntcy-server"
    }
  }
}

Example Usage

Register an agent:

register_agntcy_agent("DataBot", "Analyzes datasets", ["data-analysis", "summarization"], "https://databot.example.com")

Discover agents by capability:

discover_by_capability("data-analysis")

Create an ACP message:

create_acp_message("agent-1", "agent-2", "Please analyze this dataset", "request")
