user_disable · ArcGIS MCP: Risk & Policy

WHAT IT DOES

What user_disable does on ArcGIS MCP

AI agents use user_disable to create or update resources in ArcGIS MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ArcGIS MCP environment.

WHY IT NEEDS A POLICY

Why user_disable needs a policy

This tool modifies user state (account enabled → disabled) reversibly. While the impact is significant (user lockout), the action can be undone by re-enabling the account. This qualifies as Write rather than Destructive. Severity is high because disabling a user account can disrupt operations and affect multiple systems, but it is not irreversible like deletion.

From the tool's definition Tool name 'user_disable' and description 'Desactiva la cuenta de un usuario' (Disables a user account) explicitly marked as 'OPERACIÓN DE ESCRITURA' (Write operation). Disables user access but does not delete the account or data.

Verdict

user_disable Rate-limited

user_disable stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
