compute_bearing_frequencies
AI agents invoke compute_bearing_frequencies 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.
The tool name suggests it computes bearing frequencies, which implies a calculation/computation operation. Based on sibling tools like compute_fault_frequencies, compute_band_energy, and compute_spectrum, this server performs signal processing and analysis computations.
From the tool's definition Tool name: compute_bearing_frequencies; description is empty and provides no additional context.
Documented attack patterns abuse exactly the kind of access compute_bearing_frequencies 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_bearing_frequencies:
{
"version": "1",
"default": "deny",
"tools": {
"compute_bearing_frequencies": {
"limits": [
{
"counter": "compute_bearing_frequencies_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}compute_bearing_frequencies 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_bearing_frequencies. 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_bearing_frequencies: 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_bearing_frequencies 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_bearing_frequencies 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_bearing_frequencies. 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_bearing_frequencies 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.
