AI agents call finance.amortize to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a financial calculator that retrieves computed results from a mathematical formula. Although the tool operates in the financial domain, it does not move money, commit financial obligations, or perform any write/destructive/execute operations. It simply calculates and returns informational output (schedule, payments, interest).
From the tool's definition Tool computes and returns an amortization schedule based on provided inputs (principal, rate, term, optional extra monthly payment).

Compute a loan or mortgage amortization schedule. Pass principal, annualRatePct (e.g. 6.5), and term as termMonths or termYears; optional extraMonthly adds extra principal each month. Returns the fixed monthly payment, total interest, total paid, payoff month count, and the full month-by-month schedule (payment/principal/interest/balance). Deterministic, no external calls. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for finance.amortize: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp. Nothing to install.
finance.amortize is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the finance.amortize rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for finance.amortize. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
finance.amortize is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
