The server defines 9 tools with reasonable descriptions and mostly complete input schemas. However, several critical gaps prevent a higher score: (1) Parameter descriptions are minimal, most lack actionable guidance on format, range, or constraints. For example, 'lang' parameter descriptions say only 'Language code for transcription' without specifying valid codes, format (BCP-47?), or examples. (2) Output schemas are not documented, LLMs cannot predict what fields will be returned, forcing them to guess about chaining parameters downstream. (3) Tool names are action-oriented (good) but lack consistency in parallel operations: 'supadata_transcript' vs 'supadata_check_transcript_status' introduces unnecessary verbosity. (4) Error handling is absent, no guidance on what to do when a job fails, when to retry, or how to interpret status codes. (5) No parameter validation guidance, e.g., 'limit' in supadata_crawl has no bounds documented, inviting the LLM to pass unreasonable values. The tools do follow verb_noun convention and are single-responsibility, which are strengths.

• Add output schema documentation to every tool. Document field names, types, and whether they are always present. Example for supadata_transcript: '{"type": "object", "properties": {"jobId": {"type": "string", "description": "Unique job identifier for polling"}, "transcript": {"type": "string", "description": "Transcribed text (null if async)"}}, "required": ["jobId"]}'
• Specify valid enum values for 'mode' and 'lang' parameters. E.g., lang should enumerate valid ISO-639 codes or link to documentation. mode should list all possible values.
• Add bounds to numeric parameters. E.g., limit: 1-1000 for supadata_crawl, chunkSize: 256-10485760 for supadata_transcript.
• Expand job status descriptions with retry strategy. E.g., 'If status is "queued" or "active", wait 2-5 seconds and poll again. After 10 minutes with no progress, the job likely failed, check the "failed" path for error details.'
• Differentiate between supadata_map and supadata_crawl in their descriptions. E.g., 'supadata_map discovers all URLs on a website without fetching content, use it for discovery. supadata_crawl fetches and extracts content from all URLs, use it for bulk extraction.'
• Document pagination for tools that return lists (supadata_map). Add offset/limit or cursor parameters if the API supports them.
• Add error examples to status check tools. E.g., 'If status is "failed", the error field will contain: {"error": "timeout", "message": "Video processing exceeded 30-minute limit"}. Retry with a smaller chunkSize or contact support.'
