AI agents use set_privacy to create or update resources in Telegram MCP Complete — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Telegram MCP Complete environment.
This tool modifies privacy settings on a Telegram account, which constitutes a reversible Write operation. While privacy changes affect account behavior, they are not destructive (settings can be changed back), not financial, and not code execution.
From the tool's definition Tool name 'set_privacy' and description '设置隐私选项' (set privacy options in Chinese) indicate modification of privacy settings, which alters user account configuration.
Documented attack patterns abuse exactly the kind of access set_privacy gives an agent:
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 set_privacy:
{
"version": "1",
"default": "deny",
"tools": {
"set_privacy": {
"limits": [
{
"counter": "set_privacy_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}set_privacy stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
