quick answer

agents should read the well-known discovery files before assuming which endpoints or tools exist.

use this for

  • agent onboarding
  • api catalog discovery
  • checking current mcp tool metadata

steps

  1. open the site root or a documented api page.
  2. follow the link headers for api catalog and mcp metadata.
  3. read the well-known api catalog for endpoint shape.
  4. read the mcp server card for tool names and limits.
  5. fall back to the human wiki pages for explanation.

details to know

  • the discovery files describe public contracts, not private admin tools.
  • oauth metadata is used as api-key auth metadata for agents that expect protected-resource documents.
  • server link headers help automated clients discover the same documents from normal pages.

limits and edge cases

  • agents should not treat discovery metadata as permission to call endpoints without a user key.
  • well-known pages must stay in sync with api and mcp behavior.
