Provides verified reference data for Asian countries: statutory tax brackets, VAT rates, minimum wages, public holidays (including sub-national), FX rates and settlement cycles. Includes compliance tools to check wage floors, compute taxes and employment costs, and calculate working days. Most data requires API key; public holidays free.

Example request: "Check if a salary I'm offering in Vietnam meets the statutory minimum wage requirement."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use AsiaRef Reference Data to help me. It is a free service with an MCP server at https://asiaref.dev/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
