• src/server.ts:521-652 (handler)

  Main handler function for the 'recommend_api_combination' tool. Validates input, matches categories using CanIUseService, recommends APIs using ApiRecommendationKnowledge, fetches compatibility and baseline info, generates comprehensive report.

  Input schema definition for the recommend_api_combination tool.

• src/data/api-recommendations.ts:725-766 (helper)

  Core recommendation logic using keyword mappings and API knowledge base. Called by the handler.
