  No numeric rate limits are published for the hosted MCP endpoint or the A2A endpoint. The only statement
  is that the npm package's built-in access key is "published, rate-limited + revocable" and can be
  overridden with a dedicated PHI_MCP_KEY — the number is not given. Anonymous probes on 2026-09-19
  (initialize, tools/list x2, resources/list, prompts/list, resources/read x2, one tools/call) returned
  no RateLimit-*, X-RateLimit-* or Retry-After headers and no 429.
headers:
  observed: []
  note: Response headers seen on /mcp — access-control-allow-origin, access-control-expose-headers mcp-session-id, cache-control no-cache, strict-transport-security, x-vercel-*; nothing rate-limit related.
