Mem0 actions 47

Every Mem0 action below is a callable tool any Definable persona can invoke.

Add member to project

Adds an existing user to a project (identified by `project_id` within organization `org_id`), assigning a valid system role.

Add new memory records

Stores new memory records from a list of messages, optionally inferring structured content; requires association via `agent_id`, `user_id`, `app_id`, or `run_id`.

Add organization member

Adds a new member, who must be a registered user, to an organization, assigning them a specific role.

Create a new agent

Creates a new agent with a unique `agent_id` and an optional `name`; additional metadata may be assigned by the system.

Create a new agent run

Creates a new agent run in the mem0.ai system.

Create a new application

Creates a new application, allowing metadata to be passed in the request body (not an explicit field in this action's request model); ensure `app_id` is unique to avoid potential errors or unintended updates.

Create a new organization entry

Creates a new organization entry using the provided name and returns its details.

Create a new user

Creates a new user with the specified unique `user_id` and supports associating `metadata` (not part of the request schema fields).

Create memory entry

Lists/searches existing memory entries with filtering and pagination; critically, this action retrieves memories and does *not* create new ones, despite its name.

Create project

Creates a new project with a given name within an organization that must already exist.

Create webhook

Creates a new webhook for a specific project to receive real-time notifications. Use when you need to set up event-driven integrations that trigger on memory operations.

Delete an organization

Permanently deletes an existing organization identified by its unique ID.

Delete memory by id

Permanently deletes a specific memory by its unique ID; ensure the `memory_id` exists as this operation is irreversible.

Delete entity by type and id

Call to permanently and irreversibly hard-delete an existing entity (user, agent, app, or run) and all its associated data, using its type and ID.

Delete memories

Deletes all memories matching specified filter criteria. IMPORTANT: At least one filter (agent_id, user_id, app_id, or run_id) must be provided to prevent accidental deletion of all memories. Requires delete permissions on the organization/project.

Delete memory batch with uuids

Deletes a batch of up to 1000 existing memories, identified by their UUIDs, in a single API call.

Delete project

Permanently deletes a specific project and all its associated data from an organization; this action cannot be undone and requires the project to exist within the specified organization.

Delete project member

Removes an existing member, specified by email address, from a project, immediately revoking their project-specific access; the user is not removed from the organization.

Delete webhook

Deletes a webhook and stops receiving notifications for the specified webhook ID. Use this when you no longer need webhook notifications or want to remove a specific webhook configuration.

Export data based on filters

Creates a new memory export job with optional entity filters (user_id, agent_id, app_id, run_id). Returns export job ID and confirmation message. Requires org_id and project_id. Uses default schema for memory structure if not specified.

List organizations

Retrieves a summary list of organizations for administrative oversight; returns summary data (names, IDs), not exhaustive details, despite 'detailed' in the name.

Fetch details of a specific organization

Fetches comprehensive details for an organization using its `org_id`; the `org_id` must be valid and for an existing organization.

Get list of entity filters

Retrieves predefined filter definitions for entities (e.g., by type, creation/modification date); returns definitions only, not filtered entity data.

Get entity by id

Fetches detailed information for an existing entity (user, agent, app, or run) identified by its type and unique ID.

Get event status by event ID

Retrieves a single async event by ID to check its current status and results. Use this after operations that return event IDs (e.g., add_new_memory_records) to poll for completion before proceeding with dependent operations.

Get memories by entity

Tool to retrieve all memories associated with a specific entity (user, agent, app, or run). Use when you need to fetch memories for a known entity type and ID combination.

Get memory export

Retrieves the status and results of a memory export job by its ID. Use this after creating an export job to fetch the processed memory data. The response structure matches the schema defined during export creation.

Get organization members

Fetches a list of members for a specified, existing organization.

Get project details

Fetches comprehensive details for a specified project within an organization.

Get project members

Retrieves all members for a specified project within an organization.

Get projects

Retrieves all projects for a given organization `org_id` to which the caller has access.

Get project webhooks

Retrieves all webhooks configured for a specific project. Use this to list webhook configurations including their event types, URLs, and active status.

Get user memory stats

Retrieves a summary of the authenticated user's memory activity, including total memories created, search events, and add events. Note: This endpoint is undocumented in the official mem0 API specification but is functional.

List entities

Retrieves a list of entities, optionally filtered by organization or project (prefer `org_id`/`project_id` over deprecated `org_name`/`project_name`), noting results may be summaries and subject to limits.

Perform semantic search on memories

Searches memories semantically using a natural language query and metadata filters. IMPORTANT: - At least one of 'user_id', 'agent_id', or 'run_id' MUST be provided - A non-empty 'query' string is REQUIRED for semantic search - To retrieve memories without a search query, use 'retrieve_memory_list' action instead

Remove a member from the organization

Removes a member, specified by their username, from an existing organization of which they are currently a member.

Retrieve all events for the currently logged in user

Retrieves a paginated list of events for the authenticated user, filterable and paginable via URL query parameters. This is a read-only operation that does not modify data. Supported Query Parameters (applied directly to the request URL): - `event_type` (str, optional): Filters events by their type (e.g., 'ADD', 'SEARCH'). - `start_date` (str, optional): Filters events on or after this date (format: YYYY-MM-DD). - `end_date` (str, optional): Filters events on or before this date (format: YYYY-MM-DD). - `page` (int, optional): Specifies the page number for paginated results. - `page_size` (int, optional): Number of events per page (default: 50, max: 100).

Retrieve list of memory events

Retrieves a chronological list of all memory events (e.g., user inputs, AI responses) from the Mem0 platform, providing interaction history and context for AI assistants.

Retrieve memory by id

Retrieves a complete memory entry by its unique identifier; `memory_id` must be valid and for an existing memory.

Retrieve memory history by id

Retrieves the complete version history for an existing memory, using its unique `memory_id`, to inspect its evolution or audit changes.

Retrieve memory list

Retrieves a list of memories, supporting pagination and diverse filtering (e.g., by IDs, metadata, keywords, date ranges); ensure dates are ISO 8601 and `page`/`page_size` (if used) are positive integers. REQUIRED: At least one of agent_id, user_id, app_id, or run_id must be provided.

Search memories with filters

Semantically searches memories using structured filters with an optional natural language query. If query is omitted, defaults to '*' (wildcard) for filter-only searches. Offers options to rerank results, select specific fields, and adjust similarity threshold; any provided `org_id` or `project_id` must reference a valid existing entity.

Update memory batch with uuid

Updates text for up to 1000 memories in a single batch, using their UUIDs.

Update memory text content

Updates the text content of an existing memory, identified by its `memory_id`.

Update organization member role

Updates the role of an existing member to a new valid role within an existing organization.

Update project

Updates a project by `project_id` within an `org_id`, modifying only provided fields (name, description, custom_instructions, custom_categories); list fields are fully replaced (cleared by `[]`), other omitted/null fields remain unchanged.

Update project member role

Updates the role of a specific member within a designated project, ensuring the new role is valid and recognized by the system.
