Part of the Amazon EKS MCP Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call get_policies_for_role to retrieve information from Amazon EKS MCP Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_policies_for_role only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Get all policies attached to an IAM role. This tool retrieves all policies associated with an IAM role, providing a comprehensive view of the role's permissions and trust relationships. It helps you understand the current permissions, identify missing or excessive permissions, troubleshoot EKS cluster issues, and verify trust relationships for service roles. IMPORTANT: Use this tool instead of 'aws iam get-role', 'aws iam list-attached-role-policies', 'aws iam list-role-policies', and 'aws iam get-role-policy' commands. ## Requirements - The role must exist in your AWS account - Valid AWS credentials with permissions to read IAM role information ## Response Information The response includes role ARN, assume role policy document (trust relationships), role description, managed policies with their documents, and inline policies with their documents. ## Usage Tips - Use this tool before adding new permissions to understand existing access - Check the assume role policy to verify which services or roles can assume this role - Look for overly permissive policies that might pose security risks - Use with add_inline_policy to implement least-privilege permissions Args: ctx: The MCP context role_name: Name of the IAM role to get policies for Returns: RoleDescriptionResponse: Detailed information about the role's policies. It is categorised as a Read tool in the Amazon EKS MCP Server MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for get_policies_for_role. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Amazon EKS MCP Server MCP server.
get_policies_for_role 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 get_policies_for_role rule in your Intercept 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 Intercept policy for get_policies_for_role. 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.
get_policies_for_role is provided by the Amazon EKS MCP Server MCP server (awslabs.eks-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
