MPG is maintained by one independent Malaysian developer, so every message is read by the person who actually edits the data.
Report a wrong or stale fee
The fastest route is the contribute page: it explains the sourcing rules (official pages only) and opens a prefilled application email. If you just want to point out a mistake without contributing, a plain email works too.
Write to the maintainer for corrections, missing gateways, questions about the JSON API and MCP server, or anything else about the directory. Providers are welcome to send updated official rate cards; a public source link is required before any fee changes.
