The server defines 4 read-only tools with generally clear names and descriptions. All tools have descriptions and documented input schemas with parameter types. However, there are significant gaps: (1) output schemas are undocumented, the rubric requires documenting what fields agents should expect in responses; (2) parameter descriptions lack actionable constraints (ranges, formats, examples of valid values); (3) error handling is generic (returns JSON error objects but doesn't guide recovery or classify errors as retryable/fatal); (4) no tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite all tools being read-only; (5) parameters like 'indicator_type' have enums but lack examples or clarification on when to use 'auto' vs explicit types. The tools are well-named with verb-noun structure (find_, list_, search_), and naming is consistent and clear. Naming alone accounts for the fair score; schema and error guidance pull it down.

• Document the output schema for each tool. Add a structured example response showing the fields agents should expect. E.g., 'Returns: {"profiles": [{"id": string, "display_name": string, "base_url": string, ...}], "mode": "single"|"multi"}'.
• Add min/max bounds and format examples to all numeric and string parameters. E.g., 'max_results (integer, 1 - 1000, default 100): Maximum number of matching rules to return. Must be >= 1.'
• Enhance error messages to include recovery guidance. E.g., instead of 'Invalid policy ID', return 'Policy "abc123" not found. Try calling list_access_policies() to find valid policy IDs, or use search_access_rules(scope="fmc") to search all policies.'
• Add tool annotations. Decorate all four tools with readOnlyHint=true to signal that they have no side effects.
• Clarify parameter 'indicator_type': explain when 'auto' is appropriate vs explicit types. Add: 'When "auto", the server detects the type (IP/CIDR/FQDN/SGT/realm identity). Use explicit types to avoid auto-detection overhead or enforce strict type validation.'
• Document parameter dependencies in search_access_rules. Add to description: 'If scope="policy", provide either policy_id or policy_name (not both). If scope="fmc", use policy_name_contains to filter policies. policy_name_contains is ignored when scope="policy".'
• Return paginated results for search tools. If max_results=100 is reached, include a next_cursor field so agents can fetch additional results without re-querying. This aligns with the pattern:paginated-result.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
