create_site · API-Central MCP: Risk & Policy

WHAT IT DOES

What create_site does on API-Central

AI agents use create_site 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_site needs a policy

This tool creates new data (a site entity) in the network management system, which is reversible (sites can typically be deleted or modified). It does not execute arbitrary commands, delete data irreversibly, move money, or trigger external operations with unpredictable effects. The impact is scoped to a single new site configuration.

From the tool's definition Tool name is 'create_site' and description states 'Create a new site' with requirement that 'name must be unique', indicating creation of a new configuration entity.

Verdict

create_site Rate-limited

create_site 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.

Register the API-Central MCP server in PolicyLayer and add a rule for create_site: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches API-Central. Nothing to install.

What risk level is create_site? +

create_site is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_site? +

Yes. Add a rate_limit block to the create_site rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
