AI agents use send_document 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 creates new content (document messages) in Telegram chats with side effects that are reversible through deletion. It does not execute arbitrary code, delete data irreversibly, or involve financial transactions.
From the tool's definition send_document allows transmission of files ('发送文件') to chats in a multi-account Telegram management system. The tool description explicitly describes file sending capability.
Documented attack patterns abuse exactly the kind of access send_document 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 send_document:
{
"version": "1",
"default": "deny",
"tools": {
"send_document": {
"limits": [
{
"counter": "send_document_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}send_document 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 send_document 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 send_document. 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.
send_document 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.
