identity_put_resource_policy
AI agents use identity_put_resource_policy to create or update resources in Amazon SageMaker AI MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Amazon SageMaker AI MCP Server environment.
This tool modifies IAM resource policies, which controls access permissions to AWS resources. While it creates or modifies (Write) rather than deletes, the blast radius is high because misconfigured policies could grant unintended access to resources or lock legitimate users out. Severity is high rather than critical because it is reversible and does not directly move money or delete data.
From the tool's definition Tool name 'identity_put_resource_policy' indicates creation or modification of an IAM resource policy. The 'put' verb suggests writing/upserting a policy document. No description provided to clarify exact behavior.
Attacks that exploit this kind of access
identity_put_resource_policy. It is categorised as a Write tool in the Amazon SageMaker AI MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Amazon SageMaker AI MCP Server MCP server in PolicyLayer and add a rule for identity_put_resource_policy: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Amazon SageMaker AI MCP Server. Nothing to install.
identity_put_resource_policy is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the identity_put_resource_policy rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for identity_put_resource_policy. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
identity_put_resource_policy is provided by the Amazon SageMaker AI MCP Server MCP server (awslabs.sagemaker-ai-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
