  description: 'OAuth 2.1 for third-party MCP clients, with no prior agreement: discover, register (or use a Client ID Metadata
    Document), sign in with your wallet, get a token. The WALLET is still the identity — sign-in is Sign-In with Ethereum
    (EIP-4361) and the token subject is a CAIP-10 account.


    Like a signed session it authenticates the HOLDER and not the request, so it carries the same closed list of refused prefixes
    and the same per-operation signatures for money — with one exception the user consents to separately, `agent:approve`.
    Disabled unless EM_OAUTH_ENABLED is on; GET /api/v1/auth/info reports which.'
scopes:
- scope: agent:approve
  description: 'Approve a submission, which RELEASES the escrowed bounty to the worker. This moves money: consented on its

docs: https://execution.market/skill/reference/oauth.md#the-nine-scopes
notes:
- The AS advertises nine scopes; the MCP protected-resource metadata advertises five (the bearer-usable subset minus agent:approve).
  Three scopes (worker:submit, worker:withdraw, reputation:rate) answer 403 for ANY bearer whatever it holds — use ERC-8128
  for those.
- Default challenge scope on the MCP endpoint is task:read (observed WWW-Authenticate).
- 'Step-up: an operation lacking scope answers 403 insufficient_scope naming the scope; re-authorize asking for that scope
  PLUS the ones already held or the user loses the rest.'
