  http_status: 422
  note: An anonymous MCP tools/list (and initialize) is rejected with -32001 until the
    calling agent supplies a resolvable agent profile URI. The live per-tool
    inputSchema therefore requires an identified agent. The tool list below is NOT
    guessed — it is the method set of the OpenRPC schema BrewDog's own
    /.well-known/ucp names as the schema for this endpoint.

rules:
- Checkout requires contemporaneous human approval; agents must not complete payment
  without explicit buyer consent (stated in https://brewdog.com/agents.md).
- The MCP endpoint is rate-limited per IP; back off on 429.
- Pass context.address_country and context.currency for accurate pricing/availability.
