WHAT IT DOES

What check_trilium does on Mcp Nettools

AI agents call check_trilium 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_trilium is rated Low

This tool retrieves status information about a Trilium Notes instance by sending a GET request to its root endpoint. GET requests are inherently read-only operations that query service availability without modifying data, creating resources, executing arbitrary code, or causing destructive effects.

From the tool's definition Tool performs a reachability check via GET / request to a Trilium Notes service, which is a read-only health/status probe operation.

check_trilium Allowed

check_trilium is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
