Viral Loops MCP by usefulapi

Use your Viral Loops account from Claude, Cursor, or any MCP client. Read campaign stats, participants, referrals, ranks and rewards. Hosted, no local install: connect with your own credentials.

Live endpoint: https://viral-loops.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://viral-loops.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http viral-loops https://viral-loops.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": {
    "viral-loops": {
      "url": "https://viral-loops.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 Viral Loops credentials.

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

On first connect you provide the campaign secret API token (campaign editor → Settings → Installation). One token covers one campaign. The server validates it and stores it per user. No keys go in config files.
