  What this check looks for
Description, as the server wrote it
Free. Use right before paying an x402 seller: screens the payTo wallet against the OFAC list, checks that payTo is a wallet this seller lists in the x402 Bazaar or Circle catalogue (catches a swapped or injected payTo), looks up the seller's payer history, age and uptime, and checks the amount against the seller's listed price and your budget. Returns allow, review or deny with reasons and a signed verdict. Input: url of the resource, pay_to from its 402, optional amount_usd, max_usd, network, mode (strict: deny instead of review on a wallet mismatch or missing pay_to).

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as factline. Review it before you use it.

An Atom feed. Works in any feed reader or Slack's RSS app.

Anlyon alternative

45 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
