WHAT IT DOES

What api_help does on MCP Project Standards Server

AI agents call api_help to retrieve information from MCP Project Standards Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Why api_help needs a policy

This tool only retrieves and displays documentation/help content. It has no side effects, does not modify data, and cannot cause harm. It is purely informational, explaining how to use other tools.

From the tool's definition provides detailed documentation and examples for all API debugging tools

POLICY

How to control api_help

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "api_help": {}
  }
}

api_help is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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