Automate discovery in Claude Code

Pipe your interview transcripts directly into the `validate_customer_discovery` tool. It provides a brutal, objective assessment of your findings right in your terminal. Claude Code uses this data to challenge your assumptions. It catches generic personas and flags them before you move to implementation.

Enforce The Mom Test protocol

Stop building based on vanity metrics. This MCP Server checks your interview logs for leading questions and rejects any data that isn't grounded in past, specific behavior. Claude Code runs these validations in your CI/CD flow. It ensures no code is shipped for a feature that lacks documented market demand.

Verify willingness to pay

Verbal interest is a trap. This tool scans your notes for actual commitment signals, such as pilot dates or referrals, and ignores everything else. Claude Code reports on your WTP signal strength. It stops you from moving forward until you have proof of a real, paying market.
