inventory_create · Semaphore MCP: Risk & Policy

WHAT IT DOES

What inventory_create does on Semaphore

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

WHY IT NEEDS A POLICY

Why inventory_create needs a policy

The tool creates new inventory objects in a workflow automation platform. This is reversible (inventory can be deleted) and modifies system state without executing code or deleting data, fitting the Write category.

From the tool's definition Tool name 'inventory_create' combined with server context (Semaphore managing Ansible/Terraform workflows) indicates creation of inventory resources.

Verdict

inventory_create Rate-limited

inventory_create 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.

What risk level is inventory_create? +

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

Can I rate-limit inventory_create? +

Yes. Add a rate_limit block to the inventory_create 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.
