Convex vs MongoDB Atlas for AI agents
As of 11 Oct 2026, Convex gets an AI agent further: L3 · Does the work against L1 · Needs a person.
- Find: Docs for agents: llms.txt, an OpenAPI and an MCP server.
- Access: Runs locally: Can't sign up for one.
- Use: 70% of the work.
- Pay: Payment not reached.
- Leave: Leaves on its own: Nothing to cancel, made nothing to delete.
Got in; payment not reached. Next: let an agent sign up for an account on its own (without one it does 70% of the core work)
Gets in on its own, L3 · Does the work: a documented no-account route provisions a local deployment, where our agent pushed schema and functions, inserted and patched documents, ran an HTTP action, a cron and a scheduler, and set env vars, each checked back. The cloud side stopped at sign-up: a visible Cloudflare "Verify you are human" challenge blocked account creation, so no cloud project, deploy key or MCP session followed. Core backend work, plus file storage, text and vector search, custom-JWT auth and live subscriptions, ran on the local deployment; cloud paying and account deletion stayed out of reach, since both sit behind that same human checkpoint and the dashboard.

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.

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.
