surface_note: >-
  Travel World publishes no REST contract. Its two surfaces are an OAuth-gated remote MCP server and a
  bearer-gated A2A JSON-RPC endpoint, both on travel.augworlds.ai, and neither could be introspected
  without an invite-only member credential. Every convention below is therefore what the provider
  publishes on its one public docs page plus what the discovery documents and observed 401s show; where
  nothing is published the value is an honest none/undocumented, not a guess.
auth:
  style: OAuth 2.1 (dynamic client registration + authorization_code + PKCE S256) for MCP; tvl_ personal access token as a Bearer fallback; opaque ApiKey Bearer for A2A
  detail: authentication/augworlds-ai-authentication.yml
idempotency:
  supported: false
  coverage: none
  mechanism: null
  header: null
  scope: []
  retention: undocumented
  description: >-
    No idempotency mechanism is documented on any public surface. The write-shaped scopes
    (mcp:profile:apply, mcp:observations:write) imply mutating tools exist, but their input schemas are
    behind the OAuth gate and nothing public describes replay protection.
dry_run_mode:
  supported: false
  grade: none
  description: No dry-run, preview or simulate mode is documented.
reversibility:
  grade: none
  write_surfaces:
  - surface: mcp:profile:apply
    reversal: undocumented
    window: undocumented
  - surface: mcp:observations:write
    reversal: undocumented
    window: undocumented
  - surface: booking / payment
    reversal: not applicable to the agent
    window: null
    note: >-
      The home page states the agent "won't book, pay, cancel, or check you in" and that checkout is a
      Stripe Link "a human checks out — you, on the web. Nothing is ever charged without you present."
      Money movement is deliberately kept outside the agent surface, so the highest-stakes action has no
      agent-side reversal to grade. Cancellation of a purchased fare is the travel partner's policy, and
      none is published here.
  description: >-
    A reversal path exists for nothing an agent can call; no cancel/undo/restore operation and no window
    is stated anywhere public. Graded none rather than na because write scopes are published.

secrets_handling:
  guidance: >-
    Verbatim from the docs: read the tvl_ token from an environment variable, never commit it, and never
    paste it into a chat window — "anything you type to an agent is model input".
crawl_policy:
  travel.augworlds.ai: robots.txt disallows all user agents (private beta); public docs are on augworlds.ai
  augworlds.ai: robots.txt allows / and lists /mcp in the sitemap (lastmod 2026-07-23)
