  Create Wellness states that a rate limit exists but publishes no number. The
  full text is: "Respect rate limits. The MCP endpoint is rate-limited per IP.
  Back off on 429 responses." That is a scope (per-IP), a status code (429) and
  a required client behaviour (back off) with no quota, no window, no burst, and
  no named response headers. limit_count is therefore 0 — zero enumerable
  limits — even though a limiting policy is acknowledged.

    note: >-
      A per-request query-cost score returned on the tools/list response. It is
      the closest thing to a budget signal this surface emits, but no ceiling,
      window or remaining-balance header accompanies it, so an agent can read
      what a call cost and still not know what it has left.

    standard rate-limit header family is present and no Retry-After guidance is
    published beyond "back off".

  An agent cannot budget against this API. It is told a per-IP limit exists and
  is handed a per-call complexity score, but no quota, no window, no remaining
  balance, and no Retry-After — so it learns it is over the line only by being
  refused.
