WHAT IT DOES

What detect_tempo does on Aos

AI agents call detect_tempo to retrieve information from Aos without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why detect_tempo is rated Low

The tool reads and analyzes live audio data to detect BPM/tempo. It does not modify, create, delete, or trigger any external actions — it is purely an analytical/observational operation. Marked EXPERIMENTAL which slightly lowers confidence, but the description clearly describes a read/analysis operation with no side effects mentioned.

From the tool's definition 'automatic tempo (BPM) detection WITHOUT manual tapping. Detects beat onsets in live audio' — it analyzes/reads audio input and returns a tempo value

RECOMMENDED RULE

The rule that runs detect_tempo safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Aos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For detect_tempo, this is the rule to start with:

detect_tempo Allowed

detect_tempo is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "detect_tempo": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Aos, apply this rule, and every detect_tempo call is checked against it from then on.

FAQ

Questions about detect_tempo

What does the detect_tempo tool do? +

EXPERIMENTAL automatic tempo (BPM) detection WITHOUT manual tapping. Detects beat onsets in live audio (kick band → RMS energy → moving-baseline threshold, reusing detect_onsets. It is categorised as a Read tool in the Aos MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on detect_tempo? +

Register the Aos MCP server in PolicyLayer and add a rule for detect_tempo: 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 Aos. Nothing to install.

What risk level is detect_tempo? +

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

Can I rate-limit detect_tempo? +

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

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

detect_tempo is provided by the Aos MCP server (@hybridlabor-api/aos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
