Nowhere in your documentation does an agent learn how to get a key without a human.

No management API, service account or programmatic key creation is described in the pages we read.

Fix this first

+2points, taking 12/16 to 14/16, past supabase.com

This is the whole list: everything we could measure and you do not pass. Another 1 point sits behind checks we could not evaluate on your domain, and each of those lines below says what would make it measurable.

  1. 1
    Programmatic key provisioningan afternoon · +2

    Document how a key is created without opening a dashboard: management API, service account or CLI. If no such path exists, that gap is the finding, not the docs.

Then, when you have room

  • MCP surface a project · +1You already talk about MCP, and nothing answered at the addresses named above. If your server is at another path, declare it at /.well-known/mcp.json: that file is what an agent reads first, and it is what makes the path stop mattering.
  • Free tier or no-card trial stated in text a project · +1If you have a free tier or a no-card trial, say so in text on the pricing page rather than in an image or a button. If you are usage-priced with no free tier, this check is one an agent will read as a cost, not a defect.

Take it with you

4 of the checks an agent depends on, planetscale.com does not pass.

None of this tells you whether an agent picked you

Everything above is a file an agent could read. Whether one actually chose you is a different measurement, and we have not run it on planetscale.com. What we have run it on is a rich text editor vendor: six agents, one brief, six isolated copies of a real codebase. All six picked the same competitor, and the vendor being studied was never named, not even on a rejection list, while the runs named and dismissed ten alternatives between them. In an earlier round, run before we isolated the copies, it was named twice and struck off both times in four words: Fully commercial, licence key required. That study is about them, not about you. It is here because it is the difference between a file and a decision.

Only domains we have actually scanned appear here, so the ranking is a floor: a competitor missing from the list has not been measured, not beaten.

Every check

Each line is one HTTP observation with a published rule, so you can rerun any of them yourself. Most are the same tomorrow if you are: the two that are not are the bot gate and the pricing page, which answer inconsistently on their own, which is why those run more than once and say so when the tries disagreed. PASS and PART are counted. UNMEASURED means we could not evaluate it, N/A means it does not apply to a product like yours, and neither is in the score or its denominator. See the formula

A · Discovery

  • PASS
    Answers an agent user-agentAnswered 200 to LetAgentsIn/1.0 (+https://letagentsin.com/methodology)
  • PASS
    llms.txt publishedllms.txt present at https://planetscale.com/llms.txt, and the 12 links we sampled across the file all answer
  • PASS
    Docs readable without JavaScript14,560 characters of text without JS, on https://planetscale.com/docs/api/service-tokens rather than on https://planetscale.com/docs
  • PASS
    On-demand agents not blockedNo on-demand agent is blocked
  • N/A
    Paths robots.txt points at answerrobots.txt names no concrete path, only patterns or nothing, so there is no claim to check
  • PASS
    No punishing crawl delayNo Crawl-delay applies to the agents we check

B · Agent entry

  • PASS
    Agent entry pointFound: https://planetscale.com/skill.md
  • PASS
    OAuth dynamic client registrationregistration_endpoint published, and client_credentials is among the 4 advertised grants, so an unattended agent has a documented path to a token
  • FAIL
    MCP surfaceMCP mentioned 7x in your own files, but nothing answered at mcp.planetscale.com, mcp.planetscale.com/mcp, mcp.planetscale.com/v1/mcp, api.planetscale.com/mcp, /mcp or /api/mcpAn MCP server turns your API from something an agent reads about into something it can call.

C · Registration

  • PASS
    No CAPTCHA in the signup HTMLNo CAPTCHA vendor in the server HTML. A widget mounted later by JavaScript would not show here.
  • PASS
    Signup reachable without a browserForm renders in server HTML at https://auth.planetscale.com/sign-up

D · Provisioning

  • FAIL
    Programmatic key provisioningNone of the 7 provisioning phrases appears in the 5 documents we readDocumented key creation is the difference between a two-minute integration and a support ticket.
  • FAIL
    Free tier or no-card trial stated in textNo free tier or no-card wording at https://planetscale.com/pricingA free tier is what lets an agent finish the job in the same session it started. Usage-priced products with self-serve signup can fail this honestly, which is why it is one point and not a verdict.

E · Integration

  • PASS
    Typed SDK on the registry@planetscale/database@1.20.1 ships types, matched from the registry by who publishes it rather than by a link on your site
