## Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,700+ apps through Composio, including Zelt.
This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Zelt account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.
For exact tool slugs and parameter tables, see the [tool catalog in the Composio docs](https://docs.composio.dev/toolkits/zelt).

## Also integrate Zelt with

- [ChatGPT](https://composio.dev/toolkits/zelt/framework/chatgpt)
- [Claude Cowork](https://composio.dev/toolkits/zelt/framework/claude-cowork)
- [Hermes](https://composio.dev/toolkits/zelt/framework/hermes-agent)

## TL;DR

### How Atomic Agent connects to Zelt
Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.
Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

## Connect Zelt to Atomic Agent

### Connect Zelt to Atomic Agent
- Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key.
- In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
- Ask Atomic Agent to do something in Zelt. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your Zelt account, then return to Atomic Agent to continue.
### Headless setup
Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

```bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY
```

## 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.

## Troubleshooting

### Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

### Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

### Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing/platform) for the current limits that apply to your connection.

## Conclusion

### Use Zelt from Atomic Agent
With your account connected, ask Atomic Agent to work with Zelt in natural language. You can connect more apps through the same Composio integration as you need them.
Visit the [Atomic Agent website](https://atomicagent.io/?cta_placement=atomic-agent-site) or inspect the [Atomic Agent source code](https://github.com/AtomicBot-ai/atomic-agent?cta_placement=atomic-agent-repo).

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Zelt MCP?

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

### Can I use Tool Router MCP with Atomic Agent?

Yes, you can. Atomic Agent 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 Zelt tools.

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

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