set_cif · Oblio MCP: Risk & Policy

WHAT IT DOES

What set_cif does on Oblio

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

WHY IT NEEDS A POLICY

Why set_cif needs a policy

This tool modifies configuration state (the active tax ID) that affects all downstream operations. It is Write rather than Execute because it updates a configuration parameter rather than triggering an external operation.

From the tool's definition Tool description states it 'Sets the company CIF (Cod de Identificare Fiscala / tax ID) used for all subsequent Oblio API requests.' The verb 'Sets' indicates modification of state that persists across API calls.

Verdict

set_cif Rate-limited

set_cif 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.
