Connect

Three steps. No API key.

One remote MCP server at https://mcp.ottoai.services. Add it to your client, call a tool, and the first eligible cached call from your network address comes back free. Crypto news is paid-only and preserves that allowance.

01 — Add

Claude Code

One command. The URL is the transport — there is no path to append.

claude mcp add otto-intel --transport http https://mcp.ottoai.services

02 — Or any MCP client

Cursor, Windsurf, custom

Cursor: ~/.cursor/mcp.json. The same object works anywhere a remote MCP server is configured.

{
  "mcpServers": {
    "otto-intel": {
      "url": "https://mcp.ottoai.services"
    }
  }
}

03 — Call

The first eligible cached call is free

Ask your agent for one, or send the tools/call yourself.

{ "method": "tools/call",
  "params": { "name": "otto_pm_crypto", "arguments": {} } }

The next call returns a payment request; your agent signs it with an x402 wallet and retries with the signed payload in x_payment.
