Convex vs PlanetScale for AI agents
As of 2 Oct 2026, Convex gets an AI agent further: L3 · Does the work against L2 · Gets in.
- 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.

Gets in on its own: L2 · Gets in. Our agent signed up headless, no CAPTCHA, confirmed by email, logged in through the CLI's device flow, and pulled a service token for both the API and a hosted MCP server. It stopped trying to create a database: the API answered that it could not verify a card, and there is no free plan to work around that. Paying needs a card through Stripe Checkout; our agent never attached one, so it never reached core database work. Deleting the account needs the web UI: no API route exists for it.

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.
