Through every checkpoint. Next: pay without a person

Our agent gets in on its own: L4 · Runs on its own. Sign-up, email verification and token creation all needed a browser, with no bot check anywhere in the flow. Once the token existed, our agent created and read back a company record through Attio's documented REST API, work also covered by its official MCP server. Workflows, sequences and billing stayed browser-only. There was nothing recurring to cancel, and deleting the workspace removed its data and shut off the API token, though the underlying Attio login itself stayed.

Got in; payment not reached. Next: pay without a person

Runs on its own: L4 · Runs on its own. Signup, onboarding and the first key need a browser, and invisible reCAPTCHA let our agent through with no challenge shown. Paying is where it stopped: a trial starts without a card, but clicking add credit card at checkout did nothing in our agent's browser, so a person has to add the card. Short of that, Twenty worked headless: REST and an official MCP server let it create a company and read it back, with tools covering records, custom objects, views and workflows. Cancelling and deleting the workspace both worked on their own, with no card ever added.

Driven 2 Oct 2026 · The drive and its evidence

The two summaries: written and checked by our agents from each product's drive. How we write.

Attio or Twenty: what the difference means.

Twenty's sign-up page carries invisible reCAPTCHA, and our signed agent passed without seeing a challenge; Attio's sign-up has no CAPTCHA at all. Neither drive stopped before L4 · Runs on its own. The gap is at paying: Attio's Stripe card form under Settings > Plans rendered for our agent's browser, unfilled. Twenty's 'Add credit card' button did nothing when clicked: no popup, no Stripe request, with an hCaptcha script on the page. Paying stops there for an agent working alone.

For an agent builder

Pick Attio for straightforward CRM record work over REST, with a trial that starts without a card. Pick Twenty for workflow-heavy work: custom objects, views and AI-agent steps through its MCP and REST/GraphQL. Our agent creates the credential itself in a browser on either. Attio's access token sits under Settings > Developers; Twenty's API key is shown once, captured only after a regeneration. Paying needs a person on either.

For the owners

Attio's docs could state a sign-up policy for agents the way Twenty's llms.txt does, which already states that agent-driven sign-up is allowed. Twenty's billing button should answer an automated browser the way Attio's Settings > Plans form does, where the card page at least renders unfilled. Then paying shows what it asks for instead of a dead click.
