# auth.md: agent access to cupie.app

cupie.app is the public website of Cupie, a free video-call games app for couples. Everything an agent can use here is public and read-only. No credentials are needed, and none exist to get.

## What needs no credentials

Everything on this site:

- Every public page, as HTML or as markdown (send `Accept: text/markdown`).
- `llms.txt`, `llms-full.txt`, `sitemap.xml` and the `/.well-known/` discovery files.
- The free browser tools at `/tools`.
- The MCP endpoint at `https://cupie.app/mcp` (read-only tools: `get_product_info`, `list_public_pages`, `search_public_pages`).

It is free. There is no API key, no signup and no published rate limit; keep your request rate polite and follow `robots.txt`.

## What does not exist

cupie.app has no account system for agents. There is no registration, token, OAuth, OpenID Connect, client credential, claim, revocation or request-signing service, and no bearer scopes. Do not send an `Authorization` header: nothing reads it.

The Cupie app's own accounts, calls, messages and recordings are never reachable from this site or its MCP endpoint.
