Gets the active status of a source. Args: source_name: Name of the source to get the active status of Returns: Whether the source is active
AI agents call get_source_active 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 returns the current active/inactive state of an OBS source. It performs no modifications, deletions, or external operations—it only reads and reports status information. This is a straightforward Read operation with minimal security risk.
From the tool's definition Tool name is 'get_source_active' and description states it 'Gets the active status of a source' with return value 'Whether the source is active'. This is a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_source_active 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_source_active:
{
"version": "1",
"default": "deny",
"tools": {
"get_source_active": {}
}
}get_source_active is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Gets the active status of a source. Args: source_name: Name of the source to get the active status of Returns: Whether the source is active. 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_source_active: 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_source_active 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_source_active 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_source_active. 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_source_active 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.
