Got in; payment not reached. Next: do half of the core work (now 38%)
Gets in on its own: L2 · Gets in, signing up in a browser past an invisible reCAPTCHA. Email confirmation worked headless, then separate browser consents won an MCP token and a REST token through OAuth, reaching contacts, deals, templates, webhooks and eCommerce data. Through MCP it created a contact and read it back. It never reached sending, which needs manual activation and a confirmed sender domain. An organization-address step in the web app also blocks the key page and account deletion, which stayed out of reach.

Stopped at sign up: needs a human. Next: let an agent sign up on its own
Needs a person to get in, at L1 · Needs a person. Sign-up stops first: the form sits behind a visible Cloudflare Turnstile check, so our agent couldn't create an account. Verification, the API token page, OAuth login for CLI and MCP, the first call, paying and cancelling all read not reached for that reason. MailerLite ships Markdown docs with llms.txt, an official CLI, SDKs and a hosted MCP server, but none of it gets driven: the product stays locked behind that one form until a person clears the check and makes the key.

A check of our network and browser: It judged where our agent connects from and its browser, not a person. An agent that works on its own from a data center doesn't get through unless the owner lets signed agents in. How agents in a person's own browser fare isn't measured yet. Where we drive from.
