WHAT IT DOES

What send_group_forward_msg does on NapCat MCP Server

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

RISK

Why send_group_forward_msg is rated Medium

This tool creates/writes a new message object (a forward message) in a group chat. While it affects group state and visibility, the action is reversible through delete_msg operations available on the same server. The severity is medium because misuse could spam a group or spread misinformation, but the blast radius is limited to message transmission without data loss or financial impact.

From the tool's definition Tool name 'send_group_forward_msg' and description 'Send group forward message' indicate creation/transmission of a message to a group.
