Ground your personas in real data

Stop building for imaginary users. Use the `validate_customer_discovery` tool to force your agent to anchor every persona in specific, observed behaviors rather than vague demographics. Windsurf reads your interview transcripts and flags any persona that lacks a name, role, or company context. If you can't point to a specific conversation, the tool rejects the entry.

Test pain with The Mom Test

Stop asking leading questions that get you fake positive results. This MCP Server identifies future-tense hypotheticals and forces you to reframe them around past, factual behaviors. Windsurf applies these rules during your discovery sessions to ensure you aren't just hearing what people think you want to hear. It prioritizes actual workarounds over empty promises.

Verify commitment signals

Verbal interest is not the same as a paying customer. This tool checks your data for concrete commitment signals like pilot dates, signed LOIs, or cash deposits. If your discovery data only contains vague 'I would pay for this' comments, Windsurf flags it as high-risk. It demands proof that someone is currently losing time or money to the problem.

Common questions about Customer Discovery Prover MCP in Windsurf

Add the server to your configuration and provide your interview notes to Cascade. It will use the tool to identify if your target segment is clearly defined or just a collection of guesses.

Yes. It forces you to document the specific pain points of your first ten users. This prevents you from wasting months on features that don't solve a real problem.

Absolutely not, it does the opposite by rejecting leading questions. It acts as a filter to ensure your data is based on reality, not optimism.

It separates segments by their unique buying processes and pains. You'll see exactly which group provides actionable data versus noise.

Your transcripts remain in your local workspace. The server only processes the text you explicitly provide to the tool to generate its validation report.
