Which one, for what

Mem0 Platform + MCP C

Best for Chat products that want per-user facts back with one search call and little setup.

Ahead on

  • Schema & documentation, 80 against 61
  • Security & auth, 45 against 30
  • Maintenance & community, 85 against 70

Also in its favour

  • A hosted endpoint, with nothing to install

Watch for

Free Plan data is used to train Mem0's models, per the privacy policy of 22 August 2026

TencentDB Agent Memory C

Best 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

  • Reliability, 51 against 30
  • Agent ergonomics, 68 against 63
  • Payments & pricing, 60 against 50
  • Transparency & trust, 68 against 62

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

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.

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

Mem0 Platform + MCP

  1. Send the REST key as Authorization: Token <key>, and the MCP key as Bearer
  2. Don't search for a memory straight after adding it. Adds are queued, so poll get_event_status with the returned event ID
  3. Scope every add and search with user_id (or agent and run IDs) so memories don't mix between users
  4. Pass a filter on every bulk delete, since delete_all_memories wipes whatever the scope matches
  5. On Hobby and Starter, count retrievals rather than adds. The retrieval quota is a tenth the size

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
