wiki_admin · Agent Wiki MCP: Risk & Policy

WHAT IT DOES

What wiki_admin does on Agent Wiki

AI agents invoke wiki_admin to trigger actions in Agent Wiki. 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_admin needs a policy

Administrative tools typically perform privileged operations that can span multiple categories including configuration changes, user management, or system-level operations. The truncated description ('Select') prevents precise classification. Given it is an admin/maintenance tool on a wiki, it likely can execute privileged operations, potentially including destructive ones.

From the tool's definition 'Wiki administration and maintenance' — description is truncated/uninformative ('Select' appears to be a fragment)
