What start-migration does on AWS Labs CloudTrail MCP Server

AI agents invoke start-migration to trigger actions in AWS Labs CloudTrail MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

High Risk

Why start-migration needs a policy

The tool name 'start-migration' indicates initiation of a migration process, which is an Execute-category action—it triggers an external operation whose effects depend on arguments (target resources, migration scope, etc.). Without a description, confidence is moderate. The high severity reflects that AWS migrations can have significant blast radius: service disruptions, data movement, configuration changes.

From the tool's definition Tool named 'start-migration' with no description provided. Context suggests AWS infrastructure tooling (CloudTrail, CDK analysis, inline policies, group management). Migration tools typically trigger operational procedures with external effects.

Documented attack patterns abuse exactly the kind of access start-migration gives an agent:

How to control start-migration

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "start-migration": {
      "limits": [
        {
          "counter": "start-migration_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

start-migration stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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

Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches AWS Labs CloudTrail MCP Server. Nothing to install.

What risk level is start-migration? +

start-migration is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit start-migration? +

Yes. Add a rate_limit block to the start-migration 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 start-migration completely? +

Set action: deny in the PolicyLayer policy for start-migration. 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 start-migration? +

start-migration is provided by the AWS Labs CloudTrail MCP Server MCP server (awslabs.cloudtrail-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
