Why this exists
Every agent demo ends at the same wall
The demo always works. Then you point it at your own store, your own accounting file, your client's ad account, and you are writing an MCP server. One per vendor, each with its own auth, its own token handling, its own rate limits, its own uptime. Ten tools is ten builds and ten things to maintain before anyone has automated anything.
That work is the same for every business that needs it, which makes it a strange thing for every business to do separately. PopMCP is the version where it is already done, and three gaps in particular kept turning up in the same conversation.
