10 of 16 measurable points under formula 9.2, measured on 2026-08-12. 15 checks exist; each is one HTTP request with a published rule, so every sentence below can be rerun and argued with.
A · Discovery
- PASSAnswers an agent user-agentAnswered 200 to LetAgentsIn/1.0 (+https://letagentsin.com/methodology)
- PASSllms.txt publishedllms.txt and llms-full.txt present at https://turbopuffer.com/llms.txt and https://turbopuffer.com/llms-full.txt, and the 12 links we sampled across both files all answer
- PASSDocs readable without JavaScript10,173 characters of text without JS, on https://turbopuffer.com/docs/quickstart rather than on https://turbopuffer.com/docs/sharding
- PASSOn-demand agents not blockedNo on-demand agent is blocked
- N/APaths robots.txt points at answerrobots.txt names no concrete path, only patterns or nothing, so there is no claim to check
- PASSNo punishing crawl delayNo Crawl-delay applies to the agents we check
B · Agent entry
- FAILAgent entry pointNone of the 9 known agent entry paths returns a file rather than your page shell
- FAILOAuth dynamic client registrationNo OAuth metadata on any of the 8 hosts probed, including the usual auth and api subdomains
- FAILMCP surfaceNo MCP surface: nothing answered at mcp.turbopuffer.com, mcp.turbopuffer.com/mcp, mcp.turbopuffer.com/v1/mcp, api.turbopuffer.com/mcp, /mcp or /api/mcp, and no file mentions MCP
C · Registration
- PASSNo CAPTCHA in the signup HTMLNo CAPTCHA vendor in the server HTML. A widget mounted later by JavaScript would not show here. The page does carry kasada, a bot defence that decides in the background rather than a challenge anyone solves. We did not submit the form, so whether it lets an unattended request through is not something we measured.
- PASSSignup reachable without a browserForm renders in server HTML at https://turbopuffer.com/join
D · Provisioning
- PARTProgrammatic key provisioning1 of 7 provisioning phrases across the 4 documents we read: "service account"
- FAILFree tier or no-card trial stated in textNo free tier or no-card wording at https://turbopuffer.com/pricing
E · Integration
- PASSTyped SDK on the registry@turbopuffer/turbopuffer@2.8.0 ships types, matched from the registry by who publishes it rather than by a link on your site
- PASSMachine-readable API descriptionDocs serve markdown to machines, at https://turbopuffer.com/docs/sharding.md
Tell me when this changes
The failures here are the kind nobody notices. An edge rule that starts refusing agents changes nothing a person sees in a browser, so the first sign is usually an integration that quietly stopped working. We rescan weekly and write only when a verdict moves.
This page is the newest scan we hold for turbopuffer.com and changes when we rescan. It is not a judgement of the product: we measure whether an unattended run can get through, not whether the thing is any good. The whole corpus is published as JSON and CSV.
