Submit a publicly-accessible audio or video URL for transcription with speaker diarization. Returns a job_id you can poll with get_transcription_status, or use transcribe_audio_url_sync to wait synchronously.
AI agents call transcribe_audio_url to retrieve information from GhostMinutes MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though transcribe_audio_url only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Submit a publicly-accessible audio or video URL for transcription with speaker diarization. Returns a job_id you can poll with get_transcription_status, or use transcribe_audio_url_sync to wait synchronously. It is categorised as a Read tool in the GhostMinutes MCP MCP Server, which means it retrieves data without modifying state.
Register the GhostMinutes MCP server in PolicyLayer and add a rule for transcribe_audio_url: 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 GhostMinutes MCP. Nothing to install.
transcribe_audio_url 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 transcribe_audio_url 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 transcribe_audio_url. 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.
transcribe_audio_url is provided by the GhostMinutes MCP server (rocketech-software-development/ghostminutes-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
