Verdicts
AI Memory
Cross-agent task handoffs and shared search. Existing deployments may still lack authentication.
Mem0 Platform + MCP
An agent can create its own Free account with mem0 init --agent, no email and no card. Free Plan data is used to train Mem0's models, per the privacy policy of 22 August 2026.
Before you call either
AI Memory
- Check authentication explicitly before exposing the server beyond loopback.
- Exclude secrets and sensitive repositories from memory capture.
- Back up memory and follow the version 3 migration guide.
Mem0 Platform + MCP
- Send the REST key as
Authorization: Token <key>, and the MCP key as Bearer - Don't search for a memory straight after adding it. Adds are queued, so poll get_event_status with the returned event ID
- Scope every add and search with
user_id(or agent and run IDs) so memories don't mix between users - Pass a filter on every bulk delete, since delete_all_memories wipes whatever the scope matches
- On Hobby and Starter, count retrievals rather than adds. The retrieval quota is a tenth the size
