为指定账号ID生成登录二维码。二维码有效期为120秒，过期后可使用refresh_qr_code刷新
AI agents call generate_qr_code as a supporting operation in Telegram MCP Complete workflows.
This tool generates a QR code for account login. It neither reads user data, writes/modifies persistent data, executes commands, destroys data, nor moves money. It creates a temporary authentication artifact (valid 120s) used to initiate a login flow — this is an ephemeral credential generation step that doesn't fit cleanly into Read or Write.
From the tool's definition 生成登录二维码 (generate login QR code); 二维码有效期为120秒 (QR code valid for 120 seconds)
Documented attack patterns abuse exactly the kind of access generate_qr_code 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 generate_qr_code:
{
"version": "1",
"default": "deny",
"tools": {
"generate_qr_code": {
"limits": [
{
"counter": "generate_qr_code_rate",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
}
}generate_qr_code gets a rate cap, and everything else on the server is denied unless you say otherwise.

Register the Telegram MCP Complete MCP server in PolicyLayer and add a rule for generate_qr_code: 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.
generate_qr_code is a Other tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the generate_qr_code 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 generate_qr_code. 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.
generate_qr_code 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.
Free to start. No card required.
