THE RISK

Low Risk

Why mathematical_functions needs a policy

With no description, the tool's behavior can only be loosely inferred from its name and the server context (math computations). It likely performs read-only mathematical computations (evaluating functions, returning results) with no side effects, similar to sibling tools like 'basic_arithmetic' or 'expression_evaluator'. However, without a description, confidence is low.

From the tool's definition Tool description is empty and uninformative; only the name 'mathematical_functions' is available.

POLICY

How to control mathematical_functions

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "mathematical_functions": {
      "limits": [
        {
          "counter": "mathematical_functions_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

mathematical_functions gets a rate cap, and everything else on the server is denied unless you say otherwise.

Create a free account and register Math MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about mathematical_functions

What does the mathematical_functions tool do? +

mathematical_functions. It is categorised as a Other tool in the Math MCP Server MCP Server, which means it performs auxiliary operations.

How do I enforce a policy on mathematical_functions? +

Register the Math MCP Server MCP server in PolicyLayer and add a rule for mathematical_functions: 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 Math MCP Server. Nothing to install.

What risk level is mathematical_functions? +

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

Can I rate-limit mathematical_functions? +

Yes. Add a rate_limit block to the mathematical_functions 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 mathematical_functions completely? +

Set action: deny in the PolicyLayer policy for mathematical_functions. 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 mathematical_functions? +

mathematical_functions is provided by the Math MCP Server MCP server (111-test-111/math-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Math MCP Server tool call.

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