Why webapp_deployment_help needs a policy

The tool name suggests it may provide help or guidance related to web application deployment, which could be a Read/informational operation. However, with no description available, it's impossible to determine what this tool actually does. 'Help' in the name suggests informational content rather than an action, but confidence is very low due to the empty description.

From the tool's definition Tool name is 'webapp_deployment_help' and description is empty or uninformative.

POLICY

How to control webapp_deployment_help

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

policy.json

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

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

Create a free account and register Prometheus 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.
