# AgentAnycast

> Use this tool when you need to establish secure and decentralized communication between agents, enabling peer-to-peer interactions and skill-based routing. It solves problems related to agent discovery, NAT traversal, and end-to-end encryption, providing a robust interface for both stdio and streamable HTTP modes. Ideal for use cases requiring autonomous agent collaboration and interoperability with non-P2P agents.

## Description

Runs a libp2p-based P2P daemon that enables decentralized agent-to-agent communication using the A2A protocol. Provides automatic mDNS peer discovery on local networks, NAT traversal via circuit relay and hole punching, end-to-end encryption with Noise_XX, and skill-based anycast routing. Includes HTTP and ANP bridges for interop with non-P2P agents. Exposes P2P capabilities as MCP tools in both stdio and streamable HTTP modes.
