save_conversation · Helios-9 MCP Server MCP: Risk & Policy

WHAT IT DOES

What save_conversation does on Helios-9 MCP Server

AI agents use save_conversation to create or update resources in Helios-9 MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Helios-9 MCP Server environment.

WHY IT NEEDS A POLICY

Why save_conversation needs a policy

This tool creates or stores new data (conversation records) in a reversible manner. It does not execute code, delete data, move money, or trigger external operations. The blast radius is moderate because storing conversations with project context could inadvertently persist sensitive information, but the action itself is reversible (saved conversations can be edited or deleted by other means).

From the tool's definition Tool name is 'save_conversation' and description states 'Save an AI conversation with project context for future reference and analysis' — the verb 'Save' indicates data creation/persistence without deletion or irreversible effects.
