Connect via MCP

Dial exposes a remote MCP server over Streamable HTTP. Add the URL in your editor — do not open it in a browser tab.

Server: https://payphone.wtf/mcp (POST JSON-RPC only). OAuth: in Cursor MCP settings, click Login on the dial server (Payphone). Paid tools still use x402 on Base.

One-click setup opens your editor with a prefilled prompt — review it and press Enter before anything runs. Cursor · Claude Code · Codex
