BPM detection
AI agents call detect_tempo to retrieve information from Filopastry without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
BPM detection is an analysis operation that reads audio characteristics and returns tempo data without producing side effects, modifications to data, or irreversible changes. This is a straightforward Read category tool with minimal risk if misused by an AI agent.
From the tool's definition Tool name 'detect_tempo' with description 'BPM detection' performs audio analysis to retrieve tempo information. The sibling tool 'ai_analyze_pattern' and server description mentioning 'real-time audio analysis' confirm this is a data retrieval operation.
Attacks that exploit this kind of access
BPM detection. It is categorised as a Read tool in the Filopastry MCP Server, which means it retrieves data without modifying state.
Register the Filopastry 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 Filopastry. Nothing to install.
detect_tempo is a Read tool with low risk. Read-only tools are generally safe to allow by default.
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.
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.
detect_tempo is provided by the Filopastry MCP server (youwenshao/filopastry). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
