Implementation Reference

• src/index.ts:380-475 (handler)

  Handler for the 'get_education_data_summary' tool. Parses arguments, validates required params (level, source, topic, stat, var, by), constructs API URL with /summaries endpoint, adds query parameters for stat, var, by, filters, and makes GET request to Education Data API. Handles errors with appropriate MCP errors.
  case "get_education_data_summary": { const args = request.params.arguments || {}; const level = String(args.level || ''); const source = String(args.source || ''); const topic = String(args.topic || ''); const subtopic = args.subtopic ?
