This server has significant definition quality gaps. Tool names lack clear action verbs (add_cdn_domain is acceptable, but setup_cdn_with_text is vague). Descriptions are present but generic, most are 20-50 chars, below the 50-200 char baseline for LLM optimization. Parameter descriptions exist but lack constraints: 'sources' accepts union types with no enum or format guidance; 'protocol' accepts free-form strings instead of enums (HTTP|HTTPS|FOLLOW). No output schemas documented, tools return plain strings like 'domain added successfully' rather than structured objects. Error handling is absent: no recovery guidance, no validation of inputs, no categorization of failures. The setup_cdn_with_text tool is particularly problematic, it accepts natural language text and infers configuration, but provides no schema for what text patterns are valid or what the tool returns. No tool annotations (destructiveHint, readOnlyHint) despite delete_cdn_domain being destructive.

• Add enum constraints to schema for all constrained parameters: cdn_type=[web|download|video|live], protocol=[HTTP|HTTPS|FOLLOW], ssl_protocol=[TLSv1.2|TLSv1.3], cert_type=[upload|managed]. Remove free-form string types.
• Document output schemas for all tools. Return structured JSON: {domain_name, status, config_id, created_at} instead of plain strings. Include IDs needed for downstream tool calls.
• Add input validation with actionable error messages. E.g., 'Invalid port: 99999. Must be 1-65535.' Validate domain_name format, TTL ranges (1-31536000), and protocol values before calling API.
• Add destructiveHint annotation to delete_cdn_domain. Implement a confirm_delete tool or require explicit confirmation parameter to prevent accidental deletions.
• Replace setup_cdn_with_text with structured tools. Natural language parsing is unreliable for agent-driven configuration. If NLP is needed, wrap it in a separate service and return structured output with validation errors.
