Zadarma MCP by usefulapi

Use your Zadarma account from Claude, Cursor, or any MCP client. It reads your balance, price plan, call rates, SIP and PBX status, virtual numbers and call logs, and it can send an SMS. Hosted, no local install: connect with your own credentials.

Live endpoint: https://zadarma.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://zadarma.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http zadarma https://zadarma.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "zadarma": {
      "url": "https://zadarma.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Zadarma credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/zadarma/

On first connect you provide your Zadarma API key and secret key (my.zadarma.com → API). The server validates it and stores it per user. No keys go in config files.
