  What this check looks for

  What this check looks for

license_activateTurn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle.No findings
Why it is in this group

Description, as the server wrote it
Return the period's ledger lines as RFC 4180 CSV, one row per leg, as a download link valid for one hour. Pro, but ledger_lines returns these same fields free and unlimited; this only lays them out as CSV columns.
Annotations the server declares

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Anlyon alternative

7 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.
