bytebot_paste_text · ByteBot MCP Server MCP: Risk & Policy

WHAT IT DOES

What bytebot_paste_text does on ByteBot MCP Server

AI agents invoke bytebot_paste_text to trigger actions in ByteBot MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why bytebot_paste_text needs a policy

This tool inputs text into the desktop environment via clipboard paste, which is a direct desktop control action (keyboard/input operation). It can be misused to inject malicious text into active applications, terminal windows, or forms. The server description explicitly mentions 'direct desktop computer control' and 'mouse/keyboard operations'.

From the tool's definition Paste text directly (without typing). Faster than type_text and works with special characters/emojis.
