Why deploy_serverless_app_help needs a policy

The description is empty, providing no information about what the tool does. The name suggests it may provide help/documentation about deploying a serverless app, which could be a Read operation, but without any description, confidence is very low. On an AWS Pricing MCP server, a 'help' tool is likely informational (Read), but given the 'deploy' prefix it could potentially trigger actions.

From the tool's definition Tool name: deploy_serverless_app_help; description is empty or uninformative

POLICY

How to control deploy_serverless_app_help

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

policy.json

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

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

Create a free account and register AWS Pricing 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.
