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.
postinstall: npm install -g [email protected]
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:
SKIM_API_KEY (Recommended. Card-plan API key (sk402_...). Get a free key at https://skim402.com/pricing. Takes priority over SKIM_WALLET_PRIVATE_KEY. Enables read_url, read_urls, extract_url, crawl_url, read_pdf, watch, and poll_signal without a wallet.), SKIM_WALLET_PRIVATE_KEY (Optional. Base-network wallet private key (0x-prefixed, 64 hex chars) for x402 pay-per-call if you are not using SKIM_API_KEY. Fund with a small amount of USDC on Base. Ignored when SKIM_API_KEY is set.), SKIM_MAX_PRICE_USD (Optional cap on per-call price in USD (default 0.01). Wallet lane only. Raise (e.g. 0.05) for batch/extract/watch. Requests that would cost more than this are rejected without payment.).
The author declared them in the registry entry; get the values from the project itself.
