WHAT IT DOES

What wiki_page_render does on Mcp Wikijs Mv

AI agents invoke wiki_page_render to trigger actions in Mcp Wikijs Mv. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why wiki_page_render needs a policy

This tool triggers an operation (re-rendering/rebuilding cached HTML) on an existing page. It doesn't simply read data, nor does it create/modify the page content directly, but it executes a server-side process to rebuild cached output. It is reversible in the sense that the page content is unchanged, but it triggers an external operation on the server, placing it in the Execute category.
