create_list · Interview MCP: Risk & Policy

WHAT IT DOES

What create_list does on Interview

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

WHY IT NEEDS A POLICY

Why create_list needs a policy

Creating a list is a reversible write operation that adds new data without executing code or causing irreversible damage. The impact is limited to the user's own task management system. Severity is low because accidental or malicious list creation has minimal blast radius and can be easily undone via deletion.

From the tool's definition Tool named 'create_list' with description 'Crear lista' (Create list) - action is to create a new data structure (a list). Server description confirms 'creation' as a supported operation.
