Our reading of Base Gas, from the data
Base Gas is an MCP server from memosr, 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 (BUYER_PRIVATE_KEY); use a scoped, least-privilege key.
