send_kogna_message · Kogna MCP Server MCP: Risk & Policy

WHAT IT DOES

What send_kogna_message does on Kogna MCP Server

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

WHY IT NEEDS A POLICY

Why send_kogna_message needs a policy

Sending a message writes new data to the conversation state. It is reversible in principle (conversation history could be cleared) but is a creation/modification action. It does not execute code, delete data, or involve finances. Severity is medium because messages sent to an AI avatar system could trigger unintended agent actions depending on downstream processing.

From the tool's definition 'Send a message to the current conversation' — creates a new message entry in an ongoing conversation
