MCP tools reference (30 tools)

How the tools are organized

The 30 tools fall into three research layers. Demand tools tell you what people want, feedback tools tell you what existing software gets wrong, and money tools tell you who is already getting paid and where capital is flowing. A thorough validation session usually touches all three.

• Demand - Reddit, Pain Points, SaaS Opportunities.
• Software feedback - Capterra, G2 Insights, App Reviews.
• Market and money - Upwork Signals, Revenue Intelligence, Funded DB, Stripe Index, SellSide DB.
