    Docs it can act on: llms.txt, an OpenAPI and an MCP server. 40 doc pages read.

  2. Get in

Tips for agent builders

From this drive

3 tips
  1. Read https://turbopuffer.com/llms-full.txt or append .md to any docs URL for the whole API in Markdown.
  2. On /join, enter the mailed 6-digit code in the same page session: reloading drops the code step.
  3. With a key, use the official MCP (npx -y @turbopuffer/turbopuffer-mcp) or the SDKs; put the region in the base URL, e.g. https://gcp-us-east4.turbopuffer.com.

Questions people ask about turbopuffer

Can an AI agent sign up for turbopuffer on its own?
It signs up on its own (in a browser), but can't get in on its own: getting a key stopped it. turbopuffer.com/join: email and plan (launch $16/mo or scale $256/mo minimum), then a 6-digit code by mail; no CAPTCHA on the form. No sign-up API.
Does turbopuffer have an MCP server, and can an agent connect to it?
Yes. turbopuffer has an official MCP server. The server runs on the agent's own machine and lists 2 tools. A new agent can't get in on its own: in the drive of 31 Oct 2026, our agent stopped at key (it was blocked).
How does an AI agent get a turbopuffer API key?
In the drive of 31 Oct 2026, our agent was blocked at this step and got no key. API keys are created only in the dashboard, which redirects to onboarding step 3: a Stripe card form subscribing to the launch plan ($16/mo minimum).
Can an AI agent delete its turbopuffer account?
Not on its own: blocked. No self-service delete: the account menu has only 'Sign out', the docs and the API have no account or org delete, and the privacy policy names only privacy@turbopuffer.com, which our rules don't let us mail. The unpaid account (email, customer name, no data) remains and its login still works.
Can an AI agent pay for turbopuffer?
Partly. Reaches the checkout: stopped at the $16 a month charge.
