AI agents use create_folder 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.
Creating a chat folder is a write operation that adds organizational metadata to a user's Telegram account. It creates data structures but does not execute code, trigger external operations, delete data, or move funds. The operation is fully reversible (folders can be deleted or modified). Severity is low because misuse would only result in organizational clutter, not data loss or account compromise.
From the tool's definition Tool name is 'create_folder' and description states it '创建聊天文件夹' (creates chat folder). This is a data creation operation that organizes chats into folders—a reversible, non-destructive modification of user chat organization structure.
Documented attack patterns abuse exactly the kind of access create_folder 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 create_folder:
{
"version": "1",
"default": "deny",
"tools": {
"create_folder": {
"limits": [
{
"counter": "create_folder_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_folder 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.

Yes. Add a rate_limit block to the create_folder 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 create_folder. 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.
create_folder 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.
