Stopped at sign up: needs a human. Next: let an agent sign up on its own
Linear is a project-management and issue-tracking tool. An agent could not even create an account: the sign-up form shows a visible "prove you're human" check (Cloudflare Turnstile) right after the email is entered. So nothing behind sign-up (creating issues, projects, using the API, paying for a plan) could be tried.

Stopped at sign up: needs a human. Next: let an agent sign up on its own
Needs a person to start: Trello sits at L1, needs a person. Our agent reached the Atlassian sign-up form and stopped there: a visible reCAPTCHA Enterprise checkbox appeared after the email step, so no account got made. The key page, the MCP's OAuth login and the first API call were never reached, so no board work happened. A documented REST API and an official MCP server are both ready once a person signs up and gets a key or connects. Paying and downgrading run through the web UI with a credit card, never through an API our agent could drive.

Bot checks, and where a person was needed.

| Wall type | A check of our network and browser | A challenge on the form |
| First wall | Visible Turnstile on email sign-up | Visible reCAPTCHA on Atlassian sign-up |
| A person helped | No | No |
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. A challenge on the form: It asks every visitor to prove they are human. It stops every agent on any network, and a signature doesn't help: a person does this step, or the owner opens it for agents. Where we drive from.
