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. identity_of_provider: agent_card_signature: ES256 JWS, kid phi-a2a-2026-08, public key at https://philongevity.com/.well-known/jwks.json
