add_provider · Unlimited MCP: Risk & Policy

WHAT IT DOES

What add_provider does on Unlimited

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

WHY IT NEEDS A POLICY

Why add_provider needs a policy

'add_' prefix indicates a creation/modification operation (Write category). The broader system context—involving agent delegation, queue management, and policy controls—suggests that adding a provider could affect job routing, authentication, or resource access. Without explicit evidence of destructive deletion, financial transactions, or code execution, Write is the most appropriate classification.

From the tool's definition Tool name 'add_provider' suggests adding or registering a provider entity. In the context of a server that 'delegates coding and sysops work to cheaper agents via durable background queues,' this likely creates or modifies provider configurations.

Verdict

add_provider Rate-limited

add_provider 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.
