Gets the status of the replay buffer output. Returns: Dict containing: - outputActive: Whether the output is active

How to control get_replay_buffer_status ↓

AI agents call get_replay_buffer_status to retrieve information from OBS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Low Risk

This tool retrieves the current status of the replay buffer in OBS Studio. It performs a read-only query operation with no side effects—it does not create, modify, delete, or execute any actions. The low severity reflects minimal blast radius; misuse would only expose buffer status information without enabling unauthorized control of recording or streaming infrastructure.

From the tool's definition Tool name contains 'get_' prefix and description states it 'Gets the status of the replay buffer output' and 'Returns' information about outputActive status without modifying any state.

Documented attack patterns abuse exactly the kind of access get_replay_buffer_status gives an agent:

PolicyLayer is an MCP gateway — it sits between your AI agents and OBS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_replay_buffer_status:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_replay_buffer_status": {}
  }
}

get_replay_buffer_status is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register OBS MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
