## Why update_site_metadata is rated Medium

This tool creates or modifies site configuration metadata (title, description, SPA mode, TTL, password) without executing arbitrary code or permanently deleting data. These are reversible updates to site properties. While password changes could have security implications, the capability itself is a Write operation.

From the tool's own definition: "Tool description states 'Patch site settings' which modifies configuration data (viewer title/description, SPA mode, TTL, password)."

Risk signals: Handles credentials or secrets (password)

## Use case

AI agents use update_site_metadata to create or update resources in Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp environment.

## Recommended policy (PolicyLayer)
