## Which one, for what

### Supermemory API + MCP (B)

Good for: Apps that need user memory and document search over the same data, and for multi-tenant products that want a key per user.

Ahead on:
- Reliability, 65 against 51
- Schema & documentation, 85 against 61
- Agent ergonomics, 73 against 68
- Security & auth, 54 against 30
- Maintenance & community, 85 against 70

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No legal entity named in the terms or privacy policy

### TencentDB Agent Memory (C)

Good for: Small teams that run several coding agents on a host they control and want shared, permissioned memory, skills and code context injected through a proxy.

Ahead on:
- Payments & pricing, 60 against 30
- Transparency & trust, 68 against 51

Also in its favour:
- Free to start without a card

Watch for: The core's bearer gate is off by default, and the deploy notes say enabling it breaks the proxy's auth and session setup

## Verdicts

**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.

**TencentDB Agent Memory.** A self-hosted team memory stack with layered recall, per-asset visibility and ACLs, documented HTTP APIs and frequent releases, 2.0.0 to 2.0.3 since August. The default deployment publishes its ports on all host interfaces with the core's bearer gate off, data-plane deletes trust a service-ID header, and the proxy's rate-limit and session admin routes have no authentication.

## Before you call either

### 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

### TencentDB Agent Memory

1. Set `MEMORY_CORE_GATEWAY_API_KEY`, `KNOWLEDGE_SERVICE_KEY` and a non-default admin key before exposing ports 8420, 8424, 8096 or 8125 beyond the host
2. In headless runs send `x-team-id`, `x-agent-id` and `x-task-id` headers to the proxy. Without all three it falls back to an interactive picker and skips memory
3. Expect every proxied turn to be stored. The proxy records upstream messages and model replies to Memory Core, and injected memory lands in your system prompt
4. Check `data.valid` on `/v3/meta/auth/verify` and `data.isError` on `/v3/tools/call`. Both can fail inside a success envelope
5. Retry `/v3/session/add` only on 500, 503 or a network error. The API reference says it isn't idempotent and writes a new object each call
