WHAT IT DOES

What list_aws_reserved_instances does on Doit

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.

`status`	string	—
`pageToken`	string	—
`maxResults`	number	—
`X-Tenant-Id`	string	—

RISK

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.

RECOMMENDED RULE

The rule that runs list_aws_reserved_instances safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Doit, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_aws_reserved_instances, this is the rule to start with:

list_aws_reserved_instances Allowed

list_aws_reserved_instances is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Doit, apply this rule, and every list_aws_reserved_instances call is checked against it from then on.

Questions about list_aws_reserved_instances

What does the list_aws_reserved_instances tool do? +

Evaluate current AWS commitments, plan and automate purchases, and optimize cloud costs with PerfectScale for Commitments.
