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 Kaleido 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 Kaleido 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 Kaleido

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

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

5. Done!

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

The Kaleido MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Kaleido account. It provides structured and secure access to your blockchain environment, so your agent can perform actions like managing organizations, handling API keys, retrieving memberships, and monitoring event streams on your behalf.

  • Organization and consortium management: Let your agent list, retrieve, and manage organizations and consortia that you have access to—making it easy to keep your blockchain networks organized.
  • API key lifecycle control: Effortlessly create, retrieve, and delete API keys for your organization, so you can handle credential management without manual steps.
  • Membership and access insights: Quickly fetch details about user memberships and organizational access, helping you stay on top of roles and permissions in your blockchain environment.
  • Event stream monitoring: Retrieve and review all event streams configured in your environment, making it simple to keep tabs on real-time blockchain activity.
  • App2App and credential retrieval: Ask your agent to list App2App runtimes and fetch application credentials for specific environments, streamlining application integration and deployment.

Way Forward

With Kaleido 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 Kaleido MCP?

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

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

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