WHAT IT DOES

What send_chat_message does on Max MCP Server

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

RISK

Why send_chat_message is rated Medium

This tool creates new messages in an existing chat, which is a reversible write operation. While the message could be edited or deleted afterward, the primary action is to create and persist new data in the communication system.

From the tool's definition Tool description states 'Send a manual reply in an existing Unibox chat', which creates new message data in the chat system. The verb 'send' combined with 'manual reply' indicates data creation/modification rather than retrieval.

send_chat_message Rate-limited

send_chat_message 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.
