push_gemini_text · LINE Bot MCP Server MCP: Risk & Policy

WHAT IT DOES

What push_gemini_text does on LINE Bot MCP Server

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

WHY IT NEEDS A POLICY

Why push_gemini_text needs a policy

This tool creates and sends new messages to users, which is a reversible Write operation. While the message is sent to an external service (LINE), the action itself creates new data/communications and can be undone (deleted from the user's chat history or the account can be restricted).

From the tool's definition Tool 'push_gemini_text' generates text content via Gemini and 'push it to a LINE user as a text message' — this creates and sends a new message to a user via the LINE Messaging API. The description explicitly states message creation and transmission.
