WHAT IT DOES

What manage_aws_glue_crawlers does on CloudWatch Application Signals MCP Server

AI agents invoke manage_aws_glue_crawlers to trigger actions in CloudWatch Application Signals 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.

THE RISK

Why manage_aws_glue_crawlers needs a policy

The tool name suggests managing AWS Glue Crawlers, which could involve creating, updating, starting, stopping, or deleting crawlers. 'Manage' implies potential write and execute operations (e.g., starting/stopping crawlers triggers external AWS operations). Without a description, the most severe plausible category is Execute due to the operational nature of managing crawlers.

POLICY

How to control manage_aws_glue_crawlers

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "manage_aws_glue_crawlers": {
      "limits": [
        {
          "counter": "manage_aws_glue_crawlers_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

manage_aws_glue_crawlers 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.

Create a free account and register CloudWatch Application Signals 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.
