How to integrate Authyo MCP with Hermes

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 Authyo 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.

Api Key

Authyo is a REST API service for passwordless authentication, OTP verification, session management, and transactional notifications. Use it to add secure login flows and user verification without building auth infrastructure from scratch.

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 Authyo 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 Authyo

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

4. Done. You're all set with a new Authyo 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.

Copy MCP URL and API key from Composio dashboard

2. Open the Hermes config file

bash
nano ~/.hermes/config.yaml

3. Add the Composio Connect MCP server

bash
mcp_servers:
  composio:
    url: "https://connect.composio.dev/mcp"
    headers:
      x-consumer-api-key: "YOUR_COMPOSIO_API_KEY"
    connect_timeout: 60
    timeout: 180

Save with Ctrl + O, Enter, then exit with Ctrl + X.

4. Restart your Hermes agent

Once restarted, ask your agent to connect to Authyo or request any Authyo-related task. It will prompt you to authenticate and authorize access.

5. Done!

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

The Authyo MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Authyo account. It provides structured and secure access to passwordless authentication, user sessions, and transactional notifications, so your agent can send and verify one-time passwords, validate and revoke sessions, and send order or payment notifications on your behalf.

  • One-time password delivery: Have your agent send a one-time password to a user's email address or international phone number through your configured sender.
  • One-time password verification: Let the agent verify a user-provided code and confirm the user's identity without exposing their session token.
  • Session validation: Direct your agent to validate a session token and retrieve the identity associated with it.
  • Secure session revocation: Instruct your agent to revoke a user's session when they log out or when access should be withdrawn.
  • Order and payment notifications: Have your agent send transactional order or payment updates using Authyo's built-in templates and your configured sender.

Way Forward

With Authyo 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.

TOOLS

Supported Tools

Every Authyo action and event your agent gets out of the box.

Revoke Session

Irreversibly revoke an Authyo user session identified by its JWT, typically during logout.

Send Order Notification

Send a usage-billed order or payment notification through an Authyo built-in template; requires a configured sender.

Send OTP

Send a usage-billed one-time password to an email address or international phone number using Authyo's configured sender.

Verify OTP

Verify a user-provided OTP for an Authyo mask ID and return the verified user identity without exposing the issued session JWT.

Verify Token

Validate an Authyo session JWT and return its associated user identity without returning the JWT.

FAQ

Frequently asked questions

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

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 Authyo tools.

Yes, absolutely. You can configure which Authyo 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.

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 Authyo data and credentials are handled as safely as possible.
