WHAT IT DOES

What misp_add_attributes_bulk does on Misp

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

WHY IT NEEDS A POLICY

Why misp_add_attributes_bulk needs a policy

The tool adds (creates) new attributes within MISP events, which is a reversible write operation. It does not execute arbitrary code, delete data irreversibly, or move money. The bulk nature increases potential blast radius if an attacker injects false or malicious IOCs, but the effect is still Write-category.

From the tool's definition Tool name and description: 'Add multiple attributes (IOCs) to a MISP event at once' — this creates or modifies data by adding indicators of compromise to threat intelligence events in MISP.
