Autumn MCP by usefulapi

Autumn MCP by usefulapi

Read your Autumn customers, features, plans, balances and invoices — and create customers, track usage or attach plans — from Claude, Cursor, or any MCP client. Hosted, no local install — connect with your Autumn API key.

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

Connect

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

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

On first connect you'll paste your Autumn API key. It's validated, stored per-user, and scoped to you.
