Why generate_php_function needs a policy

This tool creates new PHP functions but does not execute them, delete existing code, or move money. The generated code would typically be saved to a file or snippet manager, making it a Write operation.

From the tool's definition Tool name and description indicate it 'Generate[s] WordPress PHP function' — this creates code artifacts that would be written to files or stored in the WordPress codebase.

POLICY

How to control generate_php_function

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "generate_php_function": {
      "limits": [
        {
          "counter": "generate_php_function_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

generate_php_function stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
