  What this check looks for
Description, as the server wrote it
Calculate the late fee on one overdue invoice: flat fee, monthly % or annual %, simple or compounding, with optional grace days. Returns days late, the fee, the new total and a line to paste on the invoice. Use payment_terms_check instead to work out when an invoice is due. Not legal advice; it does not look up state caps. Pure calculation: no network request, nothing is sent or stored. Costs $0.01 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input returns an error and is not charged.

  What this check looks for
Description, as the server wrote it
Draft a payment reminder email for one unpaid invoice in a friendly, firm or final-notice tone. Returns a subject, plain-text body, days overdue and a suggested next step. Use late_fee_calc first if you want the fee amount quoted in the email. Draft only: nothing is sent. Pure calculation: no network request, nothing is sent or stored. Costs $0.01 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input returns an error and is not charged.

6 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.
