Introduction

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows.

This guide explains the easiest and most robust way to connect your Mem0 account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

What is Composio Connect?

Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness — including Hermes. It can:

  • Search and load tools from relevant toolkits on-demand, reducing context usage.
  • Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
  • Manage app authentication end-to-end with zero manual overhead.

Integrating Mem0 with Hermes

Using Composio Connect CLI

1. Install the Composio CLI

Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

bash
curl -fsSL https://composio.dev/install | bash
Hermes authenticating with Composio

2. Authenticate

Once the CLI is installed, ask Hermes to authenticate with Composio.

3. Connect to Mem0

Ask your agent to connect to Mem0, or simply request any Mem0-related task. Hermes will prompt you to authenticate and authorize access.

4. Done. You're all set with a new Mem0 connection.


Using Composio Connect MCP

1. Get your MCP URL and API Key

Go to dashboard.composio.dev and copy your Connect MCP URL and API key.

What is the Mem0 MCP server, and what's possible with it?

The Mem0 MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Mem0 account. It provides structured and secure access to your notes, projects, and organizational knowledge, so your agent can perform actions like searching memories, managing users, adding content, and orchestrating agent runs on your behalf.

  • AI-powered memory search and recall: Let your agent search and retrieve existing memory entries using advanced filters and pagination to surface just the right note or piece of information.
  • Automated content and note creation: Have your agent store new memory records from conversations, meetings, or tasks—ensuring nothing slips through the cracks.
  • Collaboration and organization management: Direct your agent to add members to projects or organizations, assign roles, and keep team structures up to date.
  • Agent and application orchestration: Enable your agent to create new AI agents, initiate agent runs, and manage applications for custom workflows and automation.
  • Structured knowledge export and reporting: Ask your agent to initiate export jobs with specific schemas and filters, so you can back up or analyze your stored knowledge on demand.

Supported Tools & Triggers

Tools
Add member to projectAdds an existing user to a project (identified by `project id` within organization `org id`), assigning a valid system role.
Add new memory recordsStores 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 memberAdds a new member, who must be a registered user, to an organization, assigning them a specific role.
Create a new agentCreates a new agent with a unique `agent id` and an optional `name`; additional metadata may be assigned by the system.
Create a new agent runCreates a new agent run in the mem0.
Create a new applicationCreates 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 entryCreates a new organization entry using the provided name and returns its details.
Create a new userCreates a new user with the specified unique `user id` and supports associating `metadata` (not part of the request schema fields).
Create an export job with schemaInitiates an asynchronous job to export memories, structured by a schema provided in the request body and allowing optional filters.
Create memory entryLists/searches existing memory entries with filtering and pagination; critically, this action retrieves memories and does *not* create new ones, despite its name.
Create projectCreates a new project with a given name within an organization that must already exist.
Delete an organizationPermanently deletes an existing organization identified by its unique id.
Delete memory by idPermanently deletes a specific memory by its unique id; ensure the `memory id` exists as this operation is irreversible.
Delete entity by type and idCall 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 memoriesDeletes memories matching specified filter criteria; omitting all filters may result in deleting all memories.
Delete memory batch with uuidsDeletes a batch of up to 1000 existing memories, identified by their uuids, in a single api call.
Delete projectPermanently 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 memberRemoves an existing member, specified by username, from a project, immediately revoking their project-specific access; the user is not removed from the organization.
Export data based on filtersRetrieves memory export data, optionally filtered by various identifiers (e.
List organizationsRetrieves 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 organizationFetches comprehensive details for an organization using its `org id`; the `org id` must be valid and for an existing organization.
Get list of entity filtersRetrieves predefined filter definitions for entities (e.
Get entity by idFetches detailed information for an existing entity (user, agent, app, or run) identified by its type and unique id.
Get organization membersFetches a list of members for a specified, existing organization.
Get project detailsFetches comprehensive details for a specified project within an organization.
Get project membersRetrieves all members for a specified project within an organization.
Get projectsRetrieves all projects for a given organization `org id` to which the caller has access.
Get user memory statsRetrieves a summary of the authenticated user's memory activity, including total memories created, search events, and add events.
List entitiesRetrieves 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 memoriesSearches memories semantically using a natural language query (required if `only metadata based search` is false) and/or metadata filters.
Remove a member from the organizationRemoves 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 userRetrieves a paginated list of events for the authenticated user, filterable and paginable via url query parameters.
Retrieve entity-specific memoriesRetrieves all memories (e.
Retrieve list of memory eventsRetrieves a chronological list of all memory events (e.
Retrieve memory by idRetrieves a complete memory entry by its unique identifier; `memory id` must be valid and for an existing memory.
Retrieve memory history by idRetrieves the complete version history for an existing memory, using its unique `memory id`, to inspect its evolution or audit changes.
Retrieve memory listRetrieves a list of memories, supporting pagination and diverse filtering (e.
Search memories with filtersSemantically searches memories using a natural language query and mandatory structured filters, offering options to rerank results and select specific fields; any provided `org id` or `project id` must reference a valid existing entity.
Update memory batch with uuidUpdates text for up to 1000 memories in a single batch, using their uuids.
Update memory text contentUpdates the text content of an existing memory, identified by its `memory id`.
Update organization member roleUpdates the role of an existing member to a new valid role within an existing organization.
Update projectUpdates 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 roleUpdates the role of a specific member within a designated project, ensuring the new role is valid and recognized by the system.

Way Forward

With Mem0 connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.

From here, you can extend Hermes further:

  • Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
  • Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
  • Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

FAQ

What are the differences in Tool Router MCP and Mem0 MCP?

With a standalone Mem0 MCP server, the agents and LLMs can only access a fixed set of Mem0 tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Mem0 and many other apps based on the task at hand, all through a single MCP endpoint.

Can I use Tool Router MCP with Hermes?

Yes, you can. Hermes fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Mem0 tools.

Can I manage the permissions and scopes for Mem0 while using Tool Router?

Yes, absolutely. You can configure which Mem0 scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Mem0 data and credentials are handled as safely as possible.
