DECIDE FIRST
What is this project
A self-hosted AI contact and business-card MCP
What problem does it solve
Business-card data is scattered across photos, chats and paper, and remains hard to find or update after manual entry
Who it is for
- People who want to turn an open-source small project into a service they can run
- Consultants, sales professionals and freelancers who need a private contact library
What it can do
- Identify and confirm cards in ChatGPT or Claude
- Store contact data and 480px WebP thumbnails in your own D1/R2
- Provide private search, details, editing, archiving and MCP access
Before you deploy
- Your own Cloudflare Workers, D1, R2 and KV
- Web management needs a Gmail allowlist, Turnstile and an Email Service binding; MCP connections still use revocable keys
What to know first
- It is a single-owner private contact library, not a multi-user CRM or sales-automation platform
- Original card images are not stored; ChatGPT or Claude must create the thumbnail before writing, and the Worker performs no online image transformation
