identity_list_workload_identities
AI agents call identity_list_workload_identities to retrieve information from AWS IoT SiteWise MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The verb 'list' combined with 'identity_list' pattern strongly suggests querying or enumerating existing workload identities without modification. This is a Read operation with low blast radius—it retrieves data with no side effects. Confidence reduced from 0.85 to 0.7 due to the empty description, which prevents confirmation of exact behavior.
From the tool's definition Tool name 'identity_list_workload_identities' indicates a listing/enumeration operation that retrieves workload identity information. The 'list' verb is characteristically a read-only operation. Description is empty, lowering confidence slightly.
Attacks that exploit this kind of access
identity_list_workload_identities. It is categorised as a Read tool in the AWS IoT SiteWise MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AWS IoT SiteWise MCP Server MCP server in PolicyLayer and add a rule for identity_list_workload_identities: 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 AWS IoT SiteWise MCP Server. Nothing to install.
identity_list_workload_identities is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the identity_list_workload_identities 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_list_workload_identities. 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_list_workload_identities is provided by the AWS IoT SiteWise MCP Server MCP server (awslabs.aws-iot-sitewise-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
