Why decrypt_ansible_vault needs a policy

This tool executes a decryption operation on Ansible Vault encrypted content. Ansible Vault is commonly used to store sensitive secrets (passwords, API keys, private keys, credentials). Misuse by an AI agent could expose highly sensitive infrastructure secrets.

POLICY

How to control decrypt_ansible_vault

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

policy.json

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

decrypt_ansible_vault 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.

Create a free account and register IT Tools 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.
