Landing Page Copy Check

A human-guided MCP App that reviews a landing page brief, validates two or three copy variants, checks conversion basics, records explicit selection, and exports the selected copy as Markdown or HTML.

Local development

npm ci --ignore-scripts
APPROVAL_HMAC_KEY="replace-with-at-least-32-random-characters" npm test
APPROVAL_HMAC_KEY="replace-with-at-least-32-random-characters" npm start

APPROVAL_HMAC_KEY signs brief approvals and copy selections. 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 /.

Data boundary

The service is stateless and closed-world. It does not fetch URLs, change websites, make outbound network requests during tool execution, or intentionally retain briefs and exports.
