How to integrate CardClan 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 CardClan 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 CardClan 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 CardClan

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

4. Done. You're all set with a new CardClan 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 CardClan or request any CardClan-related task. It will prompt you to authenticate and authorize access.

5. Done!

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

The CardClan MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your CardClan account. It provides structured and secure access to your digital cards, workspaces, sender accounts, and integration workflows, so your agent can find cards, inspect their requirements, create personalized links, configure integrations, and send cards on your behalf.

  • Card and workspace discovery: Have your agent list accessible workspaces and find the cards available within each one.
  • Card detail review: Let the agent check a card's title, personalization requirements, and owning workspace before using it.
  • Personalized card links: Direct your agent to generate a personalized viewing link for a recipient without sending an email.
  • Card sending: Instruct your agent to choose a configured sender account, personalize a card, and email it to one or more recipients.
  • Integration workflow management: Have your agent create or review card integration setups and list cards with active workflows.

Way Forward

With CardClan 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

Frequently asked questions

With a standalone CardClan MCP server, the agents and LLMs can only access a fixed set of CardClan tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from CardClan 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 CardClan tools.

Yes, absolutely. You can configure which CardClan 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 CardClan data and credentials are handled as safely as possible.
