P2P runtime for A2A protocol. Encrypted agent communication with zero-config NAT traversal.
Connect AgentAnycast to Claude, Cursor or any other MCP client and it stops being a tab you switch to. P2P runtime for A2A protocol. Encrypted agent communication with zero-config NAT traversal. The agentanycast mcp server is what makes that connection.
AgentAnycast Node (agentanycastd) is a sidecar daemon that runs on each machine, providing P2P networking, end-to-end encryption, and A2A protocol routing. Language SDKs (Python, TypeScript) communicate with it over gRPC.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Group — MethodsPeers — ConnectPeer, ListPeers, GetPeerCardStreaming — SubscribeTaskStream, SendStreamingArtifactDiscovery — DiscoverOpenTelemetry — Distributed tracing with W3C Trace Context propagation. Spans cover task lifecycle, transport hops, and envelope encryptionConfiguration is passed through the environment: AGENTANYCAST_KEY_PATH, AGENTANYCAST_STORE_PATH. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Installation goes through your MCP client rather than a global install: point it at @modelcontextprotocol/server-filesystem on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
This sits in the planning and project tracking group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. AgentAnycast's toolset — Group, Peers, Streaming and 2 more — is a fair guide to whether it matches your workflow. It is maintained by AgentAnycast; worth a glance at recent repository activity before you build anything load-bearing on it.
