THE RISK

Why delete_integration_secret needs a policy

Deleting integration secrets is a destructive action that cannot be undone without manual intervention. If an AI agent misuses this tool, it could remove authentication credentials needed for legitimate integrations to function, causing service disruption. The blast radius is high because secret deletion breaks system integrations and may prevent legitimate API access.

From the tool's definition The tool name explicitly states 'delete' and the description confirms 'Delete an integration secret.' This is an irreversible removal of credential/authentication material.

POLICY

How to control delete_integration_secret

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_integration_secret"
  ]
}

delete_integration_secret disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Telnyx 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.
