## What ab-test-planner does, in the publisher's words

A human-guided MCP App that reviews an A/B test brief, calculates sample size and duration, validates a test plan, records explicit approval, and exports the plan as Markdown or CSV.

APPROVAL_HMAC_KEY signs explicit brief approvals. Set it explicitly for local runs; production receives it from the deployment environment file.

The local server listens on port 8790 by default. Its MCP endpoint is /mcp, health endpoints are /health and /ready, and public product pages start at /.
