Align Your Team on Real Customer Personas in VS Code Copilot

The `validate_customer_discovery` tool integrates with VS Code Copilot to ensure every feature request matches a real, documented persona with verified pain points. It keeps your development team focused on actual user feedback committed to your git repository. By committing this MCP Server configuration to your repository, your entire team gets automated validation. Your agent checks every proposed feature against actual interview notes, keeping your development roadmap honest.

Enforce Rigorous Discovery Standards Across Your Team

The `validate_customer_discovery` tool analyzes your team's shared discovery logs in VS Code to ensure you are applying strict Mom Test principles before writing code. It prevents developers from accepting hypothetical feedback during their chat sessions. The tool flags any research that relies on future promises rather than past behavior. This keeps your VS Code Copilot agent focused on building things that solve documented, painful problems with proven willingness-to-pay.

Stop Feature Creep by Segmenting Target Buyers

This MCP Server uses the `validate_customer_discovery` tool to help your team separate different buyer segments directly inside VS Code, preventing the mixing of enterprise and startup requirements. It stops your team from writing bloated code that tries to please everyone. Calling the validation tool forces your agent to map features to specific, narrow segments. It ensures you are writing code for a clearly defined group with a shared buying process, rather than a generic market.
