WHAT IT DOES

What op_script_reload_allowlists does on Mcp 1password

AI agents invoke op_script_reload_allowlists to trigger actions in Mcp 1password. 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 op_script_reload_allowlists needs a policy

This tool triggers an operational action within the MCP process — reloading allowlist configuration files. It causes a side effect (modifying the in-memory security policy/configuration of the running process) rather than simply reading or writing data. Reloading allowlists could affect which scripts are permitted to run, making it an Execute-category action.
