AI agents call retrieve_playback_id_video_assets to retrieve information from Mux 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 retrieve_playback_id_video_assets 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.

Add a rule in your Intercept YAML policy under the tools section for retrieve_playback_id_video_assets. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Mux MCP server.
retrieve_playback_id_video_assets 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 retrieve_playback_id_video_assets rule in your Intercept 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 Intercept policy for retrieve_playback_id_video_assets. 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.
retrieve_playback_id_video_assets is provided by the Mux MCP server (@mux/mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
