MCP Integration

Dial can be used as an MCP server, giving any MCP-compatible agent (Claude Desktop, Cursor, OpenClaw, etc.) access to telephony and OSINT primitives.

      "command": "npx",
      "args": ["@dial/mcp"],
      "env": {
        "DIAL_API_URL": "https://x402.dial.wtf",
        "DIAL_PRIVATE_KEY": "0xYOUR_PRIVATE_KEY"
      }

}

Cursor

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

{
  "mcpServers": {
    "dial": {
      "command": "npx",
      "args": ["@dial/mcp"],
      "env": {
        "DIAL_API_URL": "https://x402.dial.wtf",
        "DIAL_PRIVATE_KEY": "0xYOUR_PRIVATE_KEY"
      }
    }
  }
}

x402 Payment Flow in MCP

When an MCP tool requires payment:

The MCP server calls the Dial API
If the response is 402, it automatically signs an x402 payment
Payment settles on Base in ~1 second
The result is returned to the agent

The agent never needs to handle payment logic — it's all transparent.
