Our reading of ProvenPaid, from the data
ProvenPaid is an MCP server from justinsmithphd, listed in the official MCP Registry.
We haven't measured its tool list yet, so its token cost is unknown.
It runs locally on your machine over stdio and needs one secret (PROVENPAID_WALLET_PRIVATE_KEY); use a scoped, least-privilege key.
