On its own, in a browser

Can an AI agent sign up for TidyCal on its own?

Yes, in a browser, without a human. Only route is the web form /register with invisible reCAPTCHA; no sign-up API or agent registration. Done in the browser with the agent's inbox; the check let our agent's browser through.

Official server · no call worked

Does TidyCal have an MCP server, and can an agent connect to it?

Yes. TidyCal has an official MCP server. The server signs an agent in with OAuth.

A new agent can get in on its own, in a browser: in the drive of 12 Oct 2026, our agent signed up and did its work in the web app without a person. API keys need a paid plan, so it got none. Through the MCP server, 0 of our agent's 2 attempts worked.

Blocked

How does an AI agent get a TidyCal API key?

In the drive of 12 Oct 2026, our agent was blocked at this step and got no key. API tokens and the MCP server are paid-only. Integrations > API on Free: 'Unlock Integrations by upgrading'. MCP OAuth: DCR registered a client headless, but /oauth/authorize on Free answered 'For API access please upgrade to a lifetime plan!'.

On its own, in a browser

Can an AI agent delete its TidyCal account?

Yes, in a browser, without a human. Settings > Account > Delete account emails a 'Data erasure request' link; opening it deleted the account ('Your account has been successfully deleted'). Login afterwards: 'These credentials do not match our records.'; the booking page /an inbox returns 404. No API route.

Reaches the checkout

Can an AI agent pay for TidyCal?

Reaches the checkout: stopped at the card form.

Ways to pay found: Stripe Checkout (hosted card checkout) for Pro; AppSumo for lifetime plans.

No card needed to start.

What would let agents pay on their own
  1. Accept x402 or MPP on your API. Answer an unpaid call with 402 and a payment challenge, so an agent pays per call or buys credits without an account or a card.Step-by-step guide
  2. List your plans on Stripe Projects. Agents buy a plan with `stripe projects add`, paid with a token under a spend cap the owner sets (projects.dev).Step-by-step guide

No agent rail: no 402 on any TidyCal host, not in mpp.dev, Stripe Projects or the x402 Bazaar, no /.well-known/ucp, no billing API. We paid nothing. Pro is a live Stripe Checkout session (EUR 11.16/month, 'Billed monthly') reached from the pricing page while logged in; lifetime plans are sold on appsumo.com. Not paid: no card for this drive.

How an agent connects · 5 tips

/api/tools/tidycal.json/tools/tidycal.mdMCP get_tool {"slug":"tidycal"}

  • On Free, everything is in the web app: drive it in a browser; the API and MCP need Pro or a lifetime plan.
  • Booking type forms need title, URL slug and description in one go; a missing description gives 'The description field is required.'
  • The public booking page has a second email field (the footer sign-up); target the one inside the booking dialog.
  • Confirmation mails carry reschedule and cancel links with a booker_token; use them to change a booking as the attendee.
  • Account delete needs the emailed confirmation link.
