THE RISK

Why test_proxy needs a policy

This tool tests/checks proxy connectivity and measures response times. It only reads/queries the status of proxies without modifying any data or causing side effects. Equivalent to a ping or health-check operation.

From the tool's definition 测试指定或所有代理的连接状态和响应时间 (Test connection status and response time of specified or all proxies)

POLICY

How to control test_proxy

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "test_proxy": {}
  }
}

test_proxy is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Telegram MCP Complete — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
