  There is no OpenAPI to derive from (derive-authentication.py has no input). The profile below is read
  from the provider's own documentation and confirmed by live anonymous calls on 2026-09-19.
summary:
  types: [none]
  api_key_in: []
  oauth2_flows: []
  posture: Every public agent surface is unauthenticated by design.
schemes:
- name: mcp-remote-anonymous
  type: none
  surfaces: ['https://philongevity.com/mcp', 'https://philongevity.com/mcp-app']
  evidence: Anonymous POST initialize, tools/list, resources/read and tools/call all returned 200 with no credential. The provider states "No API key required for synthetic analysis" and "Stateless and carries no secrets".
  origin_policy: Requests carrying a disallowed browser Origin header get HTTP 403 before any tool runs; server-to-server callers send no Origin.
- name: a2a-anonymous
  type: none
  surfaces: ['https://philongevity.com/a2a']
  evidence: Agent card securitySchemes {} and securityRequirements [] — documented as "intentionally empty"; a consent-gated path for owner-authorized actions is in development and not live.
- name: stdio-built-in-key
  type: apiKey
  in: environment
  name_of_variable: PHI_MCP_KEY
  surfaces: ['npx -y @phi-longevity/mcp-server']
  required: false
  evidence: README — "A published, rate-limited access key is built in. If you have a dedicated key, set PHI_MCP_KEY to override it." The key authenticates the local package to Phi's gateway; the human user configures nothing.
- name: paid-tool-x402
  type: payment
  protocol: x402
  surfaces: ['https://philongevity.com/mcp#full_prism_report']
  evidence: The paid tool is gated by payment rather than identity — a base64 x402 payment payload in the `payment` parameter, per the terms returned by an unpaid call (mcp/philongevity-com-x402-payment-required.json).
human_app:
  note: The consumer application (signup at https://philongevity.com/signup) uses account login; it is out of scope for the agent surface and the provider states agents cannot act inside a user's account today.
