Mem0 List Projects

Show all known project scopes for the current user.

Execution

Step 1: Fetch memories to discover app_ids

There is no dedicated "list projects" API endpoint. Discover projects by fetching the user's memories across all scopes.

Important: A filter with only user_id triggers implicit null scoping — it excludes memories that have a non-null app_id. Run two queries and merge:

1. Null-scoped: get_memories with filters={"AND": [{"user_id": "<active_user_id>"}]}, page_size=200

— catches memories without app_id

1. App-scoped: get_memories with filters={"AND": [{"user_id": "<active_user_id>"}, {"app_id": {"exists": true}}]}, page_size=200

— catches memories with any app_id

Run both calls in parallel. Merge results, deduplicate by memory id.

If either response indicates more pages, paginate (up to 1000 total).

Step 2: Extract distinct projects

For each memory, determine project by:

1. Top-level app_id field (preferred)
2. metadata.project_id (legacy memories)
3. metadata.project (oldest format)
4. "(unscoped)" if none found

Group by resolved project name. For each project, count:

• Total memories
• Most recent created_at date
• Top 3 metadata.type values by frequency

Step 3: Display

## mem0 projects
 
  <app_id_1>  <count> memories  (last: <date>) ← current
  <app_id_2>  <count> memories  (last: <date>)
 
<N> projects, <M> total memories

Mark current project with ← current. Sort by memory count descending.

Step 4: Empty state

If zero memories found:

No projects found. Run /mem0:onboard to get started.
