AI agents call versions_get_draft to retrieve information from Piwik PRO MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about a draft version of an app in Piwik PRO Analytics. The verb 'get' and the absence of any language suggesting modification, deletion, or execution means this is a read-only query operation. The blast radius is minimal—returning draft version information poses no security or operational risk if misused by an AI agent.
From the tool's definition Tool name 'versions_get_draft' with description 'Get draft version for an app' indicates a retrieval operation with no modification or side effects.

"default": "deny",
"tools": {
"versions_get_draft": {}
}
