THE RISK

Why analyzeSchema needs a policy

With no description available, classification is uncertain. The name 'analyzeSchema' suggests a read/analysis operation (examining IAM policy schemas or resource schemas), which would be a Read category. However, on an IAM management server, schema analysis could potentially trigger operations with broader impact.

From the tool's definition Tool description is empty and uninformative; tool name 'analyzeSchema' suggests reading/analyzing a schema structure

POLICY

How to control analyzeSchema

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS IAM MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for analyzeSchema:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "analyzeSchema": {
      "limits": [
        {
          "counter": "analyzeschema_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

analyzeSchema gets a rate cap, and everything else on the server is denied unless you say otherwise.

Create a free account and register AWS IAM MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about analyzeSchema

What does the analyzeSchema tool do? +

analyzeSchema. It is categorised as a Other tool in the AWS IAM MCP Server MCP Server, which means it performs auxiliary operations.

How do I enforce a policy on analyzeSchema? +

Register the AWS IAM MCP Server MCP server in PolicyLayer and add a rule for analyzeSchema: 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 AWS IAM MCP Server. Nothing to install.

What risk level is analyzeSchema? +

analyzeSchema is a Other tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit analyzeSchema? +

Yes. Add a rate_limit block to the analyzeSchema 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.

How do I block analyzeSchema completely? +

Set action: deny in the PolicyLayer policy for analyzeSchema. 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.

What MCP server provides analyzeSchema? +

analyzeSchema is provided by the AWS IAM MCP Server MCP server (awslabs.iam-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every AWS IAM MCP Server tool call.

Start from AWS IAM MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
