Get system status from all services
AI agents call get_system_status to retrieve information from Yarr Media Stack without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries system status across media services (Sonarr, Prowlarr, Overseerr, Gotify) but performs no mutations, code execution, or destructive operations. It is purely informational, similar to a health-check or monitoring endpoint. The low severity reflects that status information poses minimal risk even if accessed by an untrusted AI agent.
From the tool's definition Tool name 'get_system_status' and description 'Get system status from all services' indicate a read-only operation that retrieves status information without modifying any state.
Attacks that exploit this kind of access
Get system status from all services. It is categorised as a Read tool in the Yarr Media Stack MCP Server, which means it retrieves data without modifying state.
Register the Yarr Media Stack MCP server in PolicyLayer and add a rule for get_system_status: 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 Yarr Media Stack. Nothing to install.
get_system_status 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_system_status 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_system_status. 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_system_status is provided by the Yarr Media Stack MCP server (mcpnexus-registry/yarr). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
