compute_time_frequency
AI agents invoke compute_time_frequency to trigger actions in Motor Current Signature Analysis. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
Based on the naming convention of sibling tools (compute_spectrum, compute_envelope_spectrum, compute_band_energy, etc.), this tool likely performs a computational analysis operation on motor current data. Computation tools in this context run signal processing algorithms, placing them in Execute. Severity is medium as misuse could produce incorrect analysis results, but direct system impact is limited.
From the tool's definition Tool name 'compute_time_frequency' and server context 'Motor Current Signature Analysis'; description is empty/uninformative.
Documented attack patterns abuse exactly the kind of access compute_time_frequency gives an agent:
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_time_frequency:
{
"version": "1",
"default": "deny",
"tools": {
"compute_time_frequency": {
"limits": [
{
"counter": "compute_time_frequency_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
} compute_time_frequency stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
compute_time_frequency. It is categorised as a Execute tool in the Motor Current Signature Analysis MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Motor Current Signature Analysis MCP server in PolicyLayer and add a rule for compute_time_frequency: 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.
compute_time_frequency is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the compute_time_frequency 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 compute_time_frequency. 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.
compute_time_frequency 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.
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.
