create_gw_policy · API-Central MCP: Risk & Policy

WHAT IT DOES

What create_gw_policy does on API-Central

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

WHY IT NEEDS A POLICY

Why create_gw_policy needs a policy

The tool creates (not deletes or executes arbitrary code) a gateway policy, which is a write operation modifying network configuration. Without a description, confidence is reduced but the 'create_' prefix and policy domain (among sibling configuration tools like 'add_devices_to_group', 'add_mac_registration') establish it as a Write-category tool.

From the tool's definition Tool name 'create_gw_policy' indicates creation of gateway policies. Server context describes 'configuration' operations for 'device migration, SSID management, switch provisioning.' Creating gateway policies is a reversible configuration change.

create_gw_policy Rate-limited

create_gw_policy 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.
