AI agents use set_slow_mode 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 group configuration settings (slow mode parameters) which affects how group members can interact, but the changes are reversible by adjusting the setting back to normal. It is a Write operation rather than Execute because it sets a specific parameter rather than running arbitrary code or commands. It is not Destructive because the setting can be easily reverted.
From the tool's definition Tool name 'set_slow_mode' and description indicating it 'sets group slow mode (user message sending interval)' - this modifies group settings by adjusting message sending intervals.
Documented attack patterns abuse exactly the kind of access set_slow_mode 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_slow_mode:
{
"version": "1",
"default": "deny",
"tools": {
"set_slow_mode": {
"limits": [
{
"counter": "set_slow_mode_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}set_slow_mode 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.

设置群组慢速模式（用户发送消息间隔）. It is categorised as a Write tool in the Telegram MCP Complete MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Telegram MCP Complete MCP server in PolicyLayer and add a rule for set_slow_mode: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Telegram MCP Complete. Nothing to install.
set_slow_mode is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the set_slow_mode rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for set_slow_mode. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
set_slow_mode is provided by the Telegram MCP Complete MCP server (you922/telegram-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Telegram MCP Complete, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
