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 Zelt 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.

For exact tool slugs and parameter tables, see the tool catalog in the Composio docs.

What is Composio Connect?

Composio Connect is a consumer offering that lets anyone plug 1,700+ 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 Zelt 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 Zelt

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

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

5. Done!

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

The Zelt MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Zelt account. It provides structured and secure access to workforce records and people operations, so your agent can create users, organize departments and roles, manage absences and attendance, and set up HR tasks and documents on your behalf.

  • Workforce and organization setup: Have your agent create users, departments, company entities, sites, job levels, job positions, and work schedules in Zelt.
  • Absence and attendance management: Let the agent create absence policies, record absences, import attendance entries, and create attendance jobs.
  • Employee records and benefits: Direct your agent to add user addresses, contracts, compensation, equity, family members, benefits, health insurance, pensions, bank accounts, tax information, roles, and ID checks.
  • HR documents and equipment: Instruct your agent to create company documents and add devices for workforce administration.
  • Requests, goals, and task planning: Have your agent create request templates, submit requests, set goals, create tasks, and add task checklists.

Way Forward

With Zelt 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.
