ZipKit MCP Server

Live: https://zipkit-mcp.scy1he02.workers.dev Thailand tax, visa & expat-money tools exposed as an MCP (Model Context Protocol) server for AI agents.

The business logic

• Free tools drive adoption: tax calculator, remittance checker, residency counter

• Premium tools monetize: remittance rule engine (multi-year planning scenarios) + Thai expert knowledge base

• Premium unlocked via x-zipkit-key header matching ZIPKIT_PREMIUM_KEY secret

• Monetization path: list on MCPize (85% rev share, they handle billing) or sell keys direct via zipkit.cc/mcp + Stripe
