THE RISK

Low Risk

Why signal_processing_calculator needs a policy

With no description available, classification is based solely on the tool name. 'signal_processing_calculator' suggests mathematical computations related to signal processing (e.g., FFT, filters), which would be a Read/compute operation with no side effects. Given the server context of mathematical computation tools, this is most likely a pure computation tool. Confidence is low due to the empty description.

From the tool's definition Tool description is empty and uninformative; tool name 'signal_processing_calculator' only suggests mathematical signal processing computations.

POLICY

How to control signal_processing_calculator

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 signal_processing_calculator:

policy.json

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

signal_processing_calculator 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 signal_processing_calculator

What does the signal_processing_calculator tool do? +

signal_processing_calculator. 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 signal_processing_calculator? +

Register the Math MCP Server MCP server in PolicyLayer and add a rule for signal_processing_calculator: 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 signal_processing_calculator? +

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

Can I rate-limit signal_processing_calculator? +

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

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

signal_processing_calculator 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.
