Gets an array of all groups in OBS. Returns: List of group names
AI agents call get_group_list 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 queries and retrieves existing data (group names) from OBS Studio without modifying, executing, or deleting anything. It is a pure read operation with minimal security impact—knowing the group structure in OBS poses negligible risk.
From the tool's definition Tool name 'get_group_list' and description 'Gets an array of all groups in OBS' with return value 'List of group names' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_group_list 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_group_list:
{
"version": "1",
"default": "deny",
"tools": {
"get_group_list": {}
}
}get_group_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Gets an array of all groups in OBS. Returns: List of group names. 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_group_list: 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_group_list 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_group_list 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_group_list. 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_group_list 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.
