How to control mcp_telnyx_delete_assistant

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 mcp_telnyx_delete_assistant:

policy.json

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

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