THE RISK

Low Risk

Why compute_envelope_spectrum needs a policy

The tool name suggests a signal processing computation (envelope spectrum analysis, commonly used in motor/bearing fault detection). Based on sibling tools, this server performs analysis tasks. With no description, it most likely reads/computes analytical data without side effects, but cannot be certain.

From the tool's definition Tool name: compute_envelope_spectrum; description is empty

POLICY

How to control compute_envelope_spectrum

PolicyLayer is an MCP gateway — it sits between your AI agents and Motor Current Signature Analysis, and nothing reaches the server without passing your rules. This is the rule we recommend for compute_envelope_spectrum:

policy.json

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

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

Create a free account and register Motor Current Signature Analysis — 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 compute_envelope_spectrum

What does the compute_envelope_spectrum tool do? +

compute_envelope_spectrum. It is categorised as a Other tool in the Motor Current Signature Analysis MCP Server, which means it performs auxiliary operations.

How do I enforce a policy on compute_envelope_spectrum? +

Register the Motor Current Signature Analysis MCP server in PolicyLayer and add a rule for compute_envelope_spectrum: 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 Motor Current Signature Analysis. Nothing to install.

What risk level is compute_envelope_spectrum? +

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

Can I rate-limit compute_envelope_spectrum? +

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

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

compute_envelope_spectrum is provided by the Motor Current Signature Analysis MCP server (LGDiMaggio/mcp-motor-current-signature-analysis). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Motor Current Signature Analysis tool call.

Start from Motor Current Signature Analysis, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
