Got in; first wall at first action (blocked). Next: let a trial or free plan reach the core features

Gets in on its own, L2 · Gets in. Our agent signed up through the web form and confirmed by email, no CAPTCHA shown. It called MCP initialize, listed tools, and read the integration list without a subscription. Sign-up and the first call held up, but the public API and CLI answered "No subscription found," and first_action stopped: there is no free plan, so no channel can be connected and nothing can be created. Paying needs a card for the trial, which our agent does not carry, so it never started a plan or reached checkout.

Stopped at sign up: needs a human. Next: let an agent sign up on its own

Needs a person: a human must sign up and make the key before any API call. Our agent read the markdown docs and the llms.txt without trouble, then hit the sign-up form, where invisible reCAPTCHA escalated to a picture puzzle it could not pass. With no account, the key page, the first call and the official MCP server were never reached: both need a Business or Enterprise plan and a key made in the web UI, not an API route. Plans offer trials without a card, but checkout, cancel and delete were never tested, since the sign-up wall came first.
