# list_aws_reserved_instances

Evaluate current AWS commitments, plan and automate purchases, and optimize cloud costs with PerfectScale for Commitments. Returns a paginated list of Reserved Instances (RIs) for the specified AWS organization. Optionally filter by state, instance type, instance family, region, and offering class. Omit filters to return all RIs for the AWS organization. This endpoint is paginated: a response with a non-empty pageToken has more results, returned when that value is passed as the pageToken parameter. A missing, null, or empty pageToken marks the last page.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "list_aws_reserved_instances",
    "arguments": {
      "managementAccountId": "<managementAccountId>"
    }
  }
}

## Why list_aws_reserved_instances is rated Low

Even though list_aws_reserved_instances only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Risk signals: High parameter count (10 properties)

## Use case

AI agents call list_aws_reserved_instances to retrieve information from Doit without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Doit:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_aws_reserved_instances": {}
  }
}
```
