Why volume_of_revolution needs a policy

This is a pure mathematical calculation tool that retrieves/computes a numerical result based on input parameters. It has no side effects, does not modify state, does not execute arbitrary code or shell commands, and does not commit financial transactions. The disk method for calculating volumes of revolution is a standard calculus operation that reads inputs and returns a computed value.

From the tool's definition Tool description states it 'Calculate[s] the volume of a solid of revolution' using mathematical integration. The function performs a mathematical computation (π∫f(x)²dx) without modifying data, executing system commands, or triggering external operations.

POLICY

How to control volume_of_revolution

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Calc Tools, and nothing reaches the server without passing your rules. This is the rule we recommend for volume_of_revolution:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "volume_of_revolution": {}
  }
}

volume_of_revolution is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

FAQ

Questions about volume_of_revolution

What does the volume_of_revolution tool do? +

Calculate the volume of a solid of revolution around the x-axis using the disk method. V = π∫f(x)²dx. Examples: volume_of_revolution(. It is categorised as a Read tool in the MCP Calc Tools MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on volume_of_revolution? +

Register the MCP Calc Tools MCP server in PolicyLayer and add a rule for volume_of_revolution: 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 Calc Tools. Nothing to install.

What risk level is volume_of_revolution? +

volume_of_revolution is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit volume_of_revolution? +

Yes. Add a rate_limit block to the volume_of_revolution 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.

How do I block volume_of_revolution completely? +

Set action: deny in the PolicyLayer policy for volume_of_revolution. 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.

What MCP server provides volume_of_revolution? +

volume_of_revolution is provided by the MCP Calc Tools MCP server (nbiish/mcp-calc-tools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every MCP Calc Tools tool call.

Start from MCP Calc Tools, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
