iam_create_key · Mimi Seed MCP: Risk & Policy

WHAT IT DOES

What iam_create_key does on Mimi Seed

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

WHY IT NEEDS A POLICY

Why iam_create_key needs a policy

Creating IAM keys is a reversible Write operation that generates authentication credentials. However, the severity is elevated to 'high' because compromised IAM keys can grant broad access to cloud resources and services. The lack of description slightly reduces confidence, but the tool name and server context (Firebase management) make the classification clear.

From the tool's definition Tool named 'iam_create_key' with no description provided. Based on naming convention, this creates Identity and Access Management (IAM) credentials/keys. The context of a Firebase management server confirms this is credential generation.
