WHAT IT DOES

What send_voice does on Xadeus-QQ-MCP

AI agents use send_voice to create or update resources in Xadeus-QQ-MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Xadeus-QQ-MCP environment.

WHY IT NEEDS A POLICY

Why send_voice needs a policy

The tool name strongly implies sending a voice message over QQ, which is a Write operation (creates/sends new data). The empty description lowers confidence, but in context of a QQ messaging server with send/receive features, this is almost certainly a message-sending action. Severity is medium since it could be used to send unsolicited voice messages to users or groups.

From the tool's definition Tool name 'send_voice' on a QQ messaging MCP server with 'message send/receive' capabilities; description is empty.
