fdl-mcp-server

Model Context Protocol server for fivedaylaunch.com — lets Claude (and any MCP-compatible AI client) audit, compare, and redesign any small business website. Free, public, no API key required.

What this does

Five tools that any MCP client can invoke:

| Tool | What it does | |---|---| | audit_website | Deterministic 5-pillar audit (Performance, SEO, Mobile, Security, AEO) → score 0-100 + specific findings | | compare_websites | Side-by-side scorecard of two sites with a winner | | ai_visibility_check | How 5 major AI engines describe any business + how to improve | | get_city_dashboard | Local economy dashboard for any US city's small business web quality | | generate_redesign_preview | Trigger a free personalized site preview emailed to a user |

All free. All call fivedaylaunch.com's public API. Zero LLM tokens consumed.

The server runs on stdio. Wire it into any MCP-compatible host (Cursor, Zed, Cline, Continue, etc.).

Why does this exist

We built fivedaylaunch.com as a free public registry of small business website quality. The audit logic is open source (fdl-site-audit). This MCP server is the canonical way to access it from inside AI assistants.

We monetize by offering full site rebuilds at $799 flat, 5 days — the audit tool is and stays free forever.
