MongoDB Atlas vs Supabase for AI agents
As of 16 Oct 2026, both reach L1 · Needs a person. Our agent got further with Supabase: with Supabase it got in and met its first wall at pay (blocked), with MongoDB Atlas it was stopped at sign up (blocked).
- Find: Docs for agents: llms.txt, an OpenAPI and an MCP server.
- Access: Can't sign up.
- Use: Work not reached.
- Pay: Payment not reached.
- Leave: Leaving not reached.
Stopped at sign up: blocked. Next: let an agent sign up on its own
Needs a person to get in: L1 · Needs a person. Sign-up stops at the web form's invisible reCAPTCHA, which answered INVALID_CAPTCHA and showed a generic server error; a retry got the same answer, and the CLI's own register page is blocked by robots.txt. With no account, verification, a key and a first call were never reached. Outside the account it reads well for agents: llms.txt, Markdown docs, a large OpenAPI spec and an official MCP server documented with CIMD-capable OAuth. Paying and leaving were never reached either, since no plan was ever started.
Driven 11 Oct 2026 · The drive and its evidence- Find: Docs for agents: llms.txt, an OpenAPI and an MCP server; a docs page for each core task.
- Access: Signs up sometimes.
- Use: 100% of the work.
- Pay: Needs a person to buy: A CAPTCHA at checkout.
- Leave: Nothing to cancel: Deletes its data, but the login stays.
Got in; first wall at pay (blocked). Next: let an agent get in on its own in every drive
Supabase is a backend platform for databases, user accounts, file storage and serverless functions. Once the agent signed in with GitHub, it could do almost everything on its own through code: create a database, add users, store files, run functions, and more. It stopped at the very first step: creating an account by email showed a puzzle test it couldn't solve, so it had to use a GitHub sign-in instead, and upgrading to a paid plan hit the same kind of puzzle.

| First wall | Invisible reCAPTCHA rejects the sign-up form | Got in; first wall at pay (blocked) |
| 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.
