import_memories · Tages MCP: Risk & Policy

WHAT IT DOES

What import_memories does on Tages

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

WHY IT NEEDS A POLICY

Why import_memories needs a policy

This tool creates or modifies memory records in the persistent storage system. While imports can overwrite existing memories, they are reversible operations (data can be re-imported, updated, or corrected in subsequent operations). This is a Write operation rather than Destructive because the changes are not irreversible — memories can be subsequently modified or corrected.

From the tool's definition Tool description states it "Import memories from a JSON array or markdown file content" and "Handles duplicates with skip/overwrite/merge strategies" — indicating creation and modification of stored memory data.
