AgentAnycast MCP Server

Turn any AI tool into a peer-to-peer agent hub. Discover, communicate with, and orchestrate AI agents across any network -- encrypted, decentralized, zero config.

uvx agentanycast-mcp

Works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, JetBrains, Gemini CLI, Amazon Q, Cline, Continue, Zed, Roo Code, and ChatGPT.

Setup

Pick your platform and add the config below. That's the entire setup -- the daemon downloads and starts automatically on first run.

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "agentanycast": {
      "command": "uvx",
      "args": ["agentanycast-mcp"]
    }
  }
}

Claude Code

claude mcp add agentanycast -- uvx agentanycast-mcp

Cursor

Add to .cursor/mcp.json in your project root:

{
  "mcpServers": {
    "agentanycast": {
      "command": "uvx",
      "args": ["agentanycast-mcp"]
    }

Cline

Add to Cline MCP settings (VS Code: Ctrl+Shift+P -> "Cline: MCP Servers"):

{
  "mcpServers": {

      "command": "uvx",
      "args": ["agentanycast-mcp"]
    }
  }

Continue

Add to ~/.continue/config.json:

{
  "experimental": {
    "modelContextProtocolServers": [
      {
        "transport": {
          "type": "stdio",
          "command": "uvx",
          "args": ["agentanycast-mcp"]
        }
      }
    ]
  }
}

Zed

Add to Zed settings (~/.config/zed/settings.json):

{
  "context_servers": {
    "agentanycast": {
      "command": {
        "path": "uvx",
        "args": ["agentanycast-mcp"]
      }
    }
  }
}

Roo Code

Add to Roo Code MCP settings (VS Code: Ctrl+Shift+P -> "Roo Code: MCP Servers"):

{
  "mcpServers": {
    "agentanycast": {
      "command": "uvx",
      "args": ["agentanycast-mcp"]
    }
  }
}

ChatGPT (HTTP mode)

Deploy the server with HTTP transport:

agentanycast-mcp --transport http --port 8080
# or: docker run -p 8080:8080 agentanycast/mcp-server

Then add http://your-server:8080/mcp in ChatGPT developer settings.

What You Can Do

Once connected, ask your AI assistant:

• "Find agents that can translate Japanese" -- discovers agents on the P2P network
• "Send 'summarize this article' to the translate agent" -- encrypted task delivery
• "What agents are connected right now?" -- lists connected peers
• "What's my Peer ID?" -- shows your node's identity and DID

Available Tools

Tool	Description	Example prompt
discover_agents	Find agents by skill	"Find agents that can translate"
send_task	Send an encrypted task to an agent	"Send 'hello' to peer 12D3KooW..."
get_task_status	Check the result of a sent task	"What was the result of that task?"
get_agent_card	Get an agent's capabilities	"What can that agent do?"
list_connected_peers	List all connected P2P peers	"Who's online?"
get_node_info	Get this node's Peer ID, DID, status	"What's my agent info?"

Configuration

Environment Variables

Set these in the "env" section of your MCP config:

Variable	Description	Default
AGENTANYCAST_RELAY	Relay server multiaddr for cross-network P2P	None (LAN only)
AGENTANYCAST_HOME	Data directory for daemon state	~/.agentanycast

Example with relay for cross-network communication:

{
  "mcpServers": {
    "agentanycast": {
      "command": "uvx",
      "args": ["agentanycast-mcp"],
      "env": {
        "AGENTANYCAST_RELAY": "/ip4/relay.agentanycast.io/tcp/4001/p2p/12D3KooW..."
      }
    }
  }
}

CLI Arguments

agentanycast-mcp [--transport stdio|http] [--port 8080] [--relay MULTIADDR] [--home DIR]

CLI arguments take priority over environment variables.

How It Works

Your AI Tool (Claude, Cursor, VS Code, ...)
    |
    | MCP protocol (stdio or HTTP)
    v
AgentAnycast MCP Server
    |
    | gRPC (Unix domain socket)
    v
AgentAnycast Daemon (Go)
    |
    | libp2p (TCP/QUIC + Noise_XX encryption + NAT traversal)
    v
Remote AI Agents (anywhere in the world)

• Zero config -- uvx agentanycast-mcp handles everything. The daemon is auto-downloaded and managed.
• Zero API keys -- agents are identified by cryptographic Peer IDs (Ed25519), not accounts or tokens.
• End-to-end encrypted -- Noise_XX protocol. Even relay servers see only ciphertext.
• NAT traversal -- works behind firewalls with automatic hole-punching and relay fallback.

What Makes This Different

This is the only MCP server that connects to a decentralized peer-to-peer network of AI agents. Other MCP servers connect to specific SaaS APIs. AgentAnycast connects you to any AI agent, anywhere, with no intermediary that can read your messages.

Troubleshooting

Daemon fails to start

• Check that port 4001 (TCP) is not in use: lsof -i :4001
• Try a clean state: rm -rf ~/.agentanycast && uvx agentanycast-mcp

No agents found on discover

• Agents must be on the same LAN (mDNS) or connected to the same relay
• Set AGENTANYCAST_RELAY to connect across networks

Connection timeout

• Behind a strict firewall? Set a relay address. The relay provides fallback connectivity.
• Check daemon logs: cat ~/.agentanycast/daemon.log

"uvx" not found

• Install uv: curl -LsSf https://astral.sh/uv/install.sh | sh
• Or install directly: pip install agentanycast-mcp

Tool calls failing

• Restart your AI tool after adding the MCP config
• Verify config JSON syntax (no trailing commas)
