calculate_wacc
Calculate Weighted Average Cost of Capital (WACC) using CAPM. Components: - Risk-free rate (US 10Y Treasury) - Beta (from comparables or financial data) - Market risk premium - Cost of debt - Tax rate - Capital structure (debt/equity weights) Uses template defaults unless overridden.

What calculate_wacc does on Nodebench
AI agents call calculate_wacc to retrieve information from Nodebench without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why calculate_wacc is rated Low
This tool performs a financial calculation using provided inputs (risk-free rate, beta, cost of debt, capital structure, etc.) and returns a computed WACC value. It does not move money, commit financial obligations, modify data, or execute code with side effects — it is purely a read/compute operation akin to a formula evaluation. No irreversible actions are taken.
From the tool's definition Calculate Weighted Average Cost of Capital (WACC) using CAPM... Uses template defaults unless overridden.
Attacks that exploit this kind of access
The rule that runs calculate_wacc safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Nodebench, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For calculate_wacc, this is the rule to start with:
calculate_wacc is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Nodebench, apply this rule, and every calculate_wacc call is checked against it from then on.
Questions about calculate_wacc
Calculate Weighted Average Cost of Capital (WACC) using CAPM. Components: - Risk-free rate (US 10Y Treasury) - Beta (from comparables or financial data) - Market risk premium - Cost of debt - Tax rate - Capital structure (debt/equity weights) Uses template defaults unless overridden. It is categorised as a Read tool in the Nodebench MCP Server, which means it retrieves data without modifying state.
Register the Nodebench MCP server in PolicyLayer and add a rule for calculate_wacc: 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 Nodebench. Nothing to install.
calculate_wacc 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 calculate_wacc 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 calculate_wacc. 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.
calculate_wacc is provided by the Nodebench MCP server (nodebench-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
