Gets the value of a slot from the selected persistent data realm
AI agents call obs-get-persistent-data 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 stored data without altering state, creating resources, executing arbitrary code, or causing financial impact. It is a straightforward read operation analogous to a key-value store lookup. The context of OBS Studio (a media broadcast tool) and sibling tools (which include scene/source management) indicates the persistent data is configuration or metadata.
From the tool's definition Tool name contains 'get' and description states 'Gets the value of a slot from the selected persistent data realm' — a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access obs-get-persistent-data 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 obs-get-persistent-data:
{
"version": "1",
"default": "deny",
"tools": {
"obs-get-persistent-data": {}
}
}obs-get-persistent-data is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Gets the value of a slot from the selected persistent data realm. 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 obs-get-persistent-data: 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.
obs-get-persistent-data 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 obs-get-persistent-data 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 obs-get-persistent-data. 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.
obs-get-persistent-data 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.
