No output schemas documented for any tool. LLMs cannot predict what fields are returned or plan downstream calls. All 10 tools lack return type documentation.

Parameter descriptions are minimal (5 - 20 chars) and lack actionable context. E.g., 'loginChallenge' has description 'The login challenge identifier', no format specification, no example of what this looks like, no guidance on where to obtain it.

No enums declared for constrained parameters. 'grant_types' and 'response_types' in createClient accept only specific values but are defined as plain arrays with no enum constraint. LLMs may hallucinate invalid values.

No error recovery guidance. Tool descriptions do not explain what can go wrong or what the LLM should do next if a call fails (e.g., 'If loginChallenge is invalid, try fetching a fresh challenge from the OAuth2 provider').

Tool descriptions lack WHEN/WHY guidance. They state WHAT the tool does but not WHEN to call it vs similar tools or what prerequisites exist. E.g., 'acceptLoginRequest' should explain 'Call this only after confirming user identity via getLoginRequest' and 'Call before acceptConsentRequest in the OAuth2 flow'.

listClients lacks pagination guidance. It accepts pageSize but no offset/cursor parameter is visible. Without documented pagination, large result sets risk context window exhaustion.

No input validation or constraint documentation for UUID fields. 'clientId' is stated to be 'UUID format' in tool description but not enforced via schema pattern or validated with clear error message if invalid.

Parameter type annotations in input schemas appear incomplete. Inspection shows 'type: string' and 'type: array' but no minLength, maxLength, pattern, or enum constraints visible, schemas lack rigor expected in production tools.
