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

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.

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

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

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

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.

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

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

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

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

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.

Permanently deletes an existing organization identified by its unique ID.

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

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.

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.

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

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.

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.

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.

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.

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

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

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

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

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.

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.

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

Fetches comprehensive details for a specified project within an organization.

Retrieves all members for a specified project within an organization.

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

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

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.

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.

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

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

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).

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.

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

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

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.

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.

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

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

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

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.

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