AI agents use set_self_destruct_timer 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 message metadata/properties (adding or changing self-destruct timers) rather than destructively deleting messages outright. The effect is reversible by changing or clearing the timer before it activates. It qualifies as Write rather than Destructive because the primary action is configuration/modification, not irreversible deletion.
From the tool's definition Tool description indicates it sets a self-destruct timer on messages (中文: '设置消息自毁时间' = 'set message self-destruct time'). This modifies message properties and behavior in Telegram secret chats.

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_self_destruct_timer:
{
"version": "1",
"default": "deny",
"tools": {
"set_self_destruct_timer": {
"limits": [
{
"counter": "set_self_destruct_timer_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}set_self_destruct_timer 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.
