Verdicts

AI Memory

Cross-agent task handoffs and shared search. Existing deployments may still lack authentication.

Supermemory API + MCP

8-tool hosted MCP with OAuth and per-space read or write permission. No legal entity named in the terms or privacy policy.

Before you call either

AI Memory

  1. Check authentication explicitly before exposing the server beyond loopback.
  2. Exclude secrets and sensitive repositories from memory capture.
  3. Back up memory and follow the version 3 migration guide.

Supermemory API + MCP

  1. Use one stable containerTag per user and a customId per session
  2. Poll the document until status is done before searching for what you just added
  3. Treat a 402 on search or profile as out of credit, not as a bug
  4. Run the prompt-based mass forget with dryRun first
  5. Call who_am_i on the MCP to see which spaces you can write to before adding

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
