WHAT IT DOES

What identity_put_resource_policy does on AWS IoT SiteWise MCP Server

AI agents use identity_put_resource_policy to create or update resources in AWS IoT SiteWise MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AWS IoT SiteWise MCP Server environment.

WHY IT NEEDS A POLICY

Why identity_put_resource_policy needs a policy

The name follows AWS conventions where 'PutResourcePolicy' creates or replaces an identity-based resource policy on a resource. This is a Write action (policy attachment/replacement), not destructive in the traditional sense but high severity because misconfigured policies can grant unintended access. Confidence is low because the description is empty, so the classification is based solely on the name pattern.

From the tool's definition Tool name: 'identity_put_resource_policy' — 'put' suggests creating or replacing a resource policy.
