create_support_case · Awslabs Valkey MCP: Risk & Policy

WHAT IT DOES

What create_support_case does on Awslabs Valkey

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

WHY IT NEEDS A POLICY

Why create_support_case needs a policy

The tool creates a new support case, which is a reversible data creation operation. This falls under Write rather than Read (no retrieval), Execute (no code execution), Destructive (reversible), Financial (no money movement), or Other. Severity is medium because creating support cases could be abused to spam AWS support with false cases, but the blast radius is limited compared to destructive or financial operations.

From the tool's definition Tool name 'create_support_case' indicates creation of a new support case resource. The sibling tools include operations like 'add_communication_to_case' and 'add_attachments_to_set', suggesting this server handles support case management as a Write operation.
