Server has 6 tools with basic schemas and descriptions, but significant gaps limit production readiness. All tools have descriptions (10-50 chars, mostly adequate) and input schemas with typed parameters. However, output schemas are completely undocumented, LLMs cannot plan downstream calls or extract return values. No error handling guidance, no recovery paths, and no security annotations (destructiveHint, readOnlyHint) despite tools ranging from READ_ONLY to DESTRUCTIVE. Tool naming is clear (verb_noun pattern), but descriptions lack context on when to use each tool vs alternatives. OAuth tools (oauth_token, oauth_introspect, oauth_revoke) are security-critical but have minimal descriptions and no guidance on prerequisites or error cases. delete_user is DESTRUCTIVE but has no confirmation pattern or dry-run option. Average tool score: 42/100.

• Document output schemas for all tools. Example for get_weather: {"type": "object", "properties": {"location": {"type": "string"}, "temperature": {"type": "string"}, "condition": {"type": "string"}, "requested_by": {"type": "string"}}, "required": ["location", "temperature", "condition"]}
• Add destructiveHint: true to delete_user schema and implement a confirm_delete_user tool or dry-run parameter to prevent accidental deletions.
• Expand oauth_token description to 100+ chars: 'Exchange authorization code for access token. Requires valid code from authorization endpoint, state for CSRF validation, and matching redirect_uri. Returns access_token, token_type, expires_in, and refresh_token if applicable.'
• Add error recovery guidance to all tools. Example: 'If location not found, try get_weather with a nearby city name or postal code.'
• Add readOnlyHint: true to get_weather and oauth_introspect; add idempotentHint: true to oauth_introspect (repeated calls return same result).
