What it does

Seller Fees Calculator is an MCP server, a connector that lets an AI assistant use it as a tool. It is installed locally as a package and runs on your machine.

From the publisher's description, Electra Index matched it to one capability: payments. That makes it a candidate for tasks such as detect fraudulent transactions or buy products online.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.
