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

RISK

Why talk_send_message is rated Medium

This tool creates new messages in a Nextcloud Talk conversation, which is a reversible write operation. While messages can be edited or deleted later, the core action is to create/post new data. It does not execute arbitrary code, delete data irreversibly, move money, or read-only access.

From the tool's definition Tool description states 'Send a message to a Talk conversation' — this creates new data (messages) in the conversation history. The mention of 'silent messages that do not trigger notifications' indicates message creation with optional side effects.
