AvailMCP has significant definition quality gaps. All three tools have descriptions, but they are vague and lack actionable detail. Tool names contain 'and' (process_csv_and_send_to_avail), signaling multiple responsibilities that should be split. Input schemas are present but lack descriptions for most parameters. Output schemas are not documented. Error handling returns raw strings without recovery guidance. No parameter validation constraints (enums, ranges, patterns) are declared. The server conflates CSV processing, OpenRank calculation, and Avail DA submission into a single tool, violating single-responsibility principle.

• Split process_csv_and_send_to_avail into three tools: (1) parse_csv_for_trust_ranking (input: csv_content, output: structured trust relationships), (2) calculate_eigentrust_rankings (input: trust relationships, output: rankings), (3) send_rankings_to_avail (input: rankings + app_id, output: transaction hash). Each tool has one responsibility.
• Add descriptions to all parameters. Example: 'app_id: Application ID registered with Avail DA (default: 89). Must be a positive integer.' For 'data' in send_data_to_avail, clarify format: 'JSON-serialized data to send to Avail DA. Will be stored as Message field.'
• Document output schemas. Example for get_data_from_avail: 'Returns object with fields: {data: string, block_number: integer, timestamp: ISO8601}'. For send_data_to_avail, specify what response.json() contains (e.g., transaction_hash, block_hash, status).
• Add input validation and error recovery guidance. Example: 'CSV must have columns: from, to, value (or i, j, v). If parsing fails, check column names and try again.' For app_id, add constraint: 'Must be a positive integer between 1 and 2^32-1.'
• Implement idempotency for send_data_to_avail by accepting an optional idempotency_key parameter. Document that repeated calls with the same key return the same result without duplicate submissions.
