WHAT IT DOES

What tokrepo_install does on TokRepo — AI Asset Registry

AI agents invoke tokrepo_install to trigger actions in TokRepo — AI Asset Registry. 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 tokrepo_install needs a policy

While the tool may appear to only fetch data, its explicit purpose is to return content 'ready to be executed' or saved as runnable files (MCP configs, workflows, scripts). An AI agent misusing this tool could retrieve and execute malicious payloads, install unauthorized skills or configurations, or trigger unintended code execution.

From the tool's definition 'Returns the content ready to be saved to a file or executed' — the tool retrieves install commands and raw content intended for direct execution or file installation.
