AI agents use send_audio 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 sends audio files to Telegram chats, which is a reversible Write operation (messages can be deleted, edited, or retracted in Telegram). It modifies the chat state by adding new content but does not execute arbitrary code, delete data irreversibly, or move funds.
From the tool's definition Tool name is 'send_audio' and description states '发送音频文件' (send audio file). This sends/uploads media content to Telegram chats, which creates new data in the messaging system.
Documented attack patterns abuse exactly the kind of access send_audio 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_audio:
{
"version": "1",
"default": "deny",
"tools": {
"send_audio": {
"limits": [
{
"counter": "send_audio_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}send_audio 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.
