Start with an onboarding workflow on signup. Right now nothing reaches a new account after day one.

  • No new tracking. Your app already sends signup to Loops.
  • A clear gap. Your two active workflows skip a new account's first week.
  • Easy to branch. projectCount splits active users from stalled ones.

Want me to create it in Loops as a draft?

Add it as a remote server with OAuth. Setup guides cover Claude Code, Codex CLI, VS Code, and more. In Cursor, use the CLI.

MCP questions

Which MCP clients work with Loops?

Any client that supports remote Streamable HTTP MCP servers and OAuth using Client ID Metadata Documents (CIMD), or is preregistered with Loops, can connect.

Do I need a Loops API key?

No. Your MCP client opens Loops in the browser and uses OAuth, so you do not need to paste an API key into the client configuration.

Can the MCP server change data or send email?

Yes. It can use Loops API operations to update contacts, manage mailing lists, send events, and send transactional email. Review write actions before approving them in your client.

Is the Claude connector a separate MCP server?

No. Claude’s directory connector uses the same Loops MCP server at https://mcp.loops.so.
