What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
env = dict(os.environ if env is None else env)
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

This one needs environment variables set before it will start:
PROVENPAID_WALLET_PRIVATE_KEY (Optional. Private key of a dedicated low-balance wallet holding USDC on Base, used only to sign payments after the 10 free checks. Not needed to try it.), PROVENPAID_DAILY_LIMIT (Maximum paid checks per UTC day (default 20).), PROVENPAID_MAX_PRICE_USD (Refuse checks priced above this (default 0.01, hard ceiling 0.10).).
