Description, as the server wrote it
WRITE: create a financial transaction for a member (a charge, or a credit when is_credit is true), e.g. an invoice line or a manual adjustment.

2 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.
