There are several stale PRs attempting this:

  • #27200 (feat(cli): support self-hosted mem0 setup) — 349 lines, 8 files
  • #22553 (feat(memory): support OSS mem0 API mode)
  • #20185 (feat(plugins): add local self-host mode to mem0)
  • #21601 (feat(memory): support self-hosted Mem0 REST backend)
  • #30902 (fix(doctor): recognize self-hosted Mem0 without API key)

The underlying Mem0 OSS package already supports self-hosted deployments with a REST API. The main work is wiring MEM0_HOST into the existing plugin.

Problem or Use Case

Proposed Solution: Add MEM0_HOST config option to the mem0 plugin — when set, use a lightweight REST client pointing to the local Mem0 OSS instance instead of the cloud API.

Context

There are several stale PRs attempting this:

  • #27200 (feat(cli): support self-hosted mem0 setup) — 349 lines, 8 files
  • #22553 (feat(memory): support OSS mem0 API mode)
  • #20185 (feat(plugins): add local self-host mode to mem0)
  • #21601 (feat(memory): support self-hosted Mem0 REST backend)
  • #30902 (fix(doctor): recognize self-hosted Mem0 without API key)

The underlying Mem0 OSS package already supports self-hosted deployments with a REST API. The main work is wiring MEM0_HOST into the existing plugin.

Requirements

  • MEM0_HOST env var (e.g. http://localhost:8888)
  • MEM0_API_KEY for self-hosted auth (or ADMIN_API_KEY via X-API-Key header)
  • Graceful fallback: if MEM0_HOST is blank → use cloud Platform as today
  • Docker-based Mem0 OSS is a common setup; this would unblock many self-hosted users
