Tanatasa provides a public shopping API, hosted MCP server and command-line tool for its Singapore skincare and beauty store.

Buyers review the cart, enter delivery details and pay on tanatasa.sg; delivery is within Singapore. Developer docs: https://tanatasa.sg/ai-agent-docs. MCP: https://tanatasa.sg/mcp.
