provision_number · Agentline MCP: Risk & Policy

WHAT IT DOES

What provision_number does on Agentline

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

WHY IT NEEDS A POLICY

Why provision_number needs a policy

Provisioning a phone number creates a new resource (allocates/registers a phone number), which is a Write operation. This likely incurs costs or external obligations, and could be misused by an AI agent to provision numbers at scale. Confidence is reduced because the tool description is empty, but the server context strongly implies phone number provisioning.

From the tool's definition Tool name 'provision_number' on a server that 'enables them to provision numbers' — server description explicitly mentions provisioning phone numbers as a capability.

Verdict

provision_number Rate-limited

provision_number 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.
