WHAT IT DOES

What save_text_to_memory does on Vector Memory MCP Server

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

WHY IT NEEDS A POLICY

Why save_text_to_memory needs a policy

This tool writes data to a memory system, which is reversible (data can be updated or managed). It does not delete data (would be Destructive), execute arbitrary code (would be Execute), nor move money (would be Financial). However, it modifies a potentially important information store that an AI agent could misuse to inject false information into its own memory, influencing future decisions.

From the tool's definition Tool name 'save_text_to_memory' explicitly indicates data creation/modification. Server description confirms it 'saves...information from files or free-form notes.' The tool creates or modifies persistent memory records.
