Gets the filename of the last replay buffer save file. Returns: Dict containing: - savedReplayPath: Path of the saved replay file
AI agents call get_last_replay_buffer_replay 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.
This tool retrieves metadata (a filename path) from OBS Studio's replay buffer state without side effects. It is a pure read operation that queries existing data and returns it. The blast radius is minimal—an AI agent misusing this tool could only learn file paths, which does not enable harmful actions on the system.
From the tool's definition Tool name contains 'get' and description states it 'Gets the filename of the last replay buffer save file' with a return value of 'savedReplayPath'. No creation, modification, deletion, or execution occurs.
Documented attack patterns abuse exactly the kind of access get_last_replay_buffer_replay 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_last_replay_buffer_replay:
{
"version": "1",
"default": "deny",
"tools": {
"get_last_replay_buffer_replay": {}
}
}get_last_replay_buffer_replay is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Gets the filename of the last replay buffer save file. Returns: Dict containing: - savedReplayPath: Path of the saved replay file. It is categorised as a Read tool in the OBS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OBS MCP Server MCP server in PolicyLayer and add a rule for get_last_replay_buffer_replay: 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 OBS MCP Server. Nothing to install.
get_last_replay_buffer_replay 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 get_last_replay_buffer_replay 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 get_last_replay_buffer_replay. 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.
get_last_replay_buffer_replay is provided by the OBS MCP Server MCP server (royshil/obs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
