WHAT IT DOES

What check_prowlarr does on Mcp Nettools

AI agents call check_prowlarr to retrieve information from Mcp Nettools without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why check_prowlarr is rated Low

This tool performs a read-only query to a Prowlarr instance's status endpoint. It retrieves system health information (version and startup time) with no side effects, no data modification, and no destructive or financial operations. The HTTP method is GET, which is inherently safe. Even if the agent can misuse the connection details (e.g., port scanning), the tool itself only reads data.

From the tool's definition Tool description states 'Check Prowlarr indexer manager health via GET /api/v1/system/status. Returns version and startup time.' — explicitly a GET request that retrieves status information without modification.
