Inspect IAM: users, roles, policies with MFA status.
AI agents call aws_iam to retrieve information from RedisNexus without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only inspection of IAM entities and their security posture. While the blast radius is high because IAM data is security-sensitive and could inform privilege escalation attacks, the tool itself performs no modifications, execution, or destructive actions.
From the tool's definition Tool description explicitly states 'Inspect IAM: users, roles, policies with MFA status' — inspect is a read-only query operation that retrieves sensitive security configuration data without modifying it.
Attacks that exploit this kind of access
Inspect IAM: users, roles, policies with MFA status. It is categorised as a Read tool in the RedisNexus MCP Server, which means it retrieves data without modifying state.
Register the RedisNexus MCP server in PolicyLayer and add a rule for aws_iam: 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 RedisNexus. Nothing to install.
aws_iam 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 aws_iam 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 aws_iam. 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.
aws_iam is provided by the RedisNexus MCP server (rajkumar-madhu/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
