Single-target operation
Part of the AWS IAM MCP Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call get_managed_policy_document to retrieve information from AWS IAM 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_managed_policy_document 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.

Retrieve the policy document for a managed policy. This tool retrieves the policy document for a specific managed policy version. Use this to examine the actual permissions and wildcards in managed policies. Args: policy_arn: The ARN of the managed policy version_id: Optional version ID (defaults to current version) Returns: ManagedPolicyResponse containing the policy document and details. It is categorised as a Read tool in the AWS IAM 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_managed_policy_document. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the AWS IAM MCP Server MCP server.
get_managed_policy_document 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_managed_policy_document 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_managed_policy_document. 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_managed_policy_document is provided by the AWS IAM MCP Server MCP server (awslabs.iam-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
