AI agents call transcribe_url to retrieve information from Scriptivox without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though transcribe_url only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Transcribe audio or video from a public URL using Scriptivox AI. Supports 119 languages, speaker diarization, and word-level timestamps. RECOMMENDED: always pass the language parameter explicitly when you know the audio language — auto-detect has a small failure rate on short clips, code-switched audio, or files starting with music. Requires a configured API key.. It is categorised as a Read tool in the Scriptivox MCP Server, which means it retrieves data without modifying state.
Register the Scriptivox MCP server in PolicyLayer and add a rule for transcribe_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 Scriptivox. Nothing to install.
transcribe_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_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_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_url is provided by the Scriptivox MCP server (oci:docker.io/sparkleofficialmain/scriptivox-mcp-server:1.1.3). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
