WHAT IT DOES

What import_memories does on Claude Memory MCP Server

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

WHY IT NEEDS A POLICY

Why import_memories needs a policy

The tool creates or modifies data in the memory store by importing and potentially overwriting existing memories. This is reversible (memories can be edited or deleted later via other tools like delete_memory), so it falls under Write rather than Destructive.

From the tool's definition Tool description states it can 'Import memories from JSON file' and 'skip or overwrite existing memories.' The ability to overwrite existing data indicates modification of stored data.
