Overview

Organizations and projects provide multi-tenant support, access control, and team collaboration capabilities for Mem0 Platform. Use these APIs to build applications that support multiple teams, customers, or isolated environments.
Organizations and projects are optional features. You can use Mem0 without them for single-user or simple multi-user applications.

​
Key Capabilities

  • Multi-org/project Support: Specify organization and project when initializing the Mem0 client to attribute API usage appropriately
  • Member Management: Control access to data through organization and project membership
  • Access Control: Only members can access memories and data within their organization/project scope
  • Team Isolation: Maintain data separation between different teams and projects for secure collaboration

​
Using Organizations & Projects

​
Initialize with Org/Project Context

Example with the mem0 Python package: 
from mem0 import MemoryClient
client = MemoryClient(api_key="your-api-key")

​
Project Management

The Mem0 client provides comprehensive project management through the client.project interface:

​
Get Project Details

Retrieve information about the current project: 
# Get all project details
project_info = client.project.get()

# Get specific fields only
project_info = client.project.get(fields=["name", "description", "custom_categories"])

​
Create a New Project

Create a new project within your organization: 
# Create a project with name and description
new_project = client.project.create(
    name="My New Project",
    description="A project for managing customer support memories"
)

​
Update Project Settings

Modify project configuration including custom instructions, categories, and language preferences: 
# Update project with custom categories
client.project.update(
    custom_categories=[
        {"customer_preferences": "Customer likes, dislikes, and preferences"},
        {"support_history": "Previous support interactions and resolutions"}
    ]
)

# Update project with custom instructions
client.project.update(
    custom_instructions="..."
)

# Use the input language for memory storage and retrieval
client.project.update(multilingual=True)

# Update multiple settings at once
client.project.update(
    custom_instructions="...",
    custom_categories=[
        {"personal_info": "User personal information and preferences"},
        {"work_context": "Professional context and work-related information"}
    ],
    multilingual=True
)

​
Toggle Memory Decay

decay is a per-project boolean that turns on Memory Decay — a search-time ranking bias that reinforces recently-accessed memories and gently dampens stale ones. The flag is false by default; set it via the same project-update endpoint:
cURL
curl -X PATCH https://api.mem0.ai/api/v1/orgs/organizations/$ORG_ID/projects/$PROJECT_ID/ \
  -H "Authorization: Token $MEM0_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"decay": true}'
The current state is returned on every project read (and supports ?fields=decay for a minimal response). Toggling has no effect on stored memories, only on how v3 search ranks them.

​
Delete Project

This action will remove all memories, messages, and other related data in the project. This operation is irreversible.
Remove a project and all its associated data: 
# Delete the current project (irreversible)
result = client.project.delete()

​
Member Management

Manage project members and their access levels: 
# Get all project members
members = client.project.get_members()

# Add a new member as a reader
client.project.add_member(
    email="[email protected]",
    role="READER"  # or "OWNER"
)

# Update a member's role
client.project.update_member(
    email="[email protected]",
    role="OWNER"
)

# Remove a member from the project
client.project.remove_member(email="[email protected]")

​
Member Roles

RolePermissions
READERCan view and search memories, but cannot modify project settings or manage members
OWNERFull access including project modification, member management, and all reader permissions

​
Async Support

All project methods are available in async mode: 
from mem0 import AsyncMemoryClient

async def manage_project():
    client = AsyncMemoryClient(api_key="your-api-key")

    # All methods support async/await
    project_info = await client.project.get()
    await client.project.update(multilingual=True)
    members = await client.project.get_members()

# To call the async function properly
import asyncio
asyncio.run(manage_project())
