WHAT IT DOES

What mcp_install_plugin does on Wordpress

RISK

Why mcp_install_plugin is rated High

RECOMMENDED RULE

The rule that runs mcp_install_plugin safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Wordpress, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mcp_install_plugin, this is the rule to start with:

mcp_install_plugin Rate-limited

mcp_install_plugin 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.

View as policy code

policy.json

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

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Wordpress, apply this rule, and every mcp_install_plugin call is checked against it from then on.
