## Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including Cronfree Time Scheduler.
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 Cronfree Time Scheduler account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.

## TL;DR

### How Atomic Agent connects to Cronfree Time Scheduler
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 Cronfree Time Scheduler to Atomic Agent

### Connect Cronfree Time Scheduler 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 Cronfree Time Scheduler. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your Cronfree Time Scheduler 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 Cronfree Time Scheduler MCP server, and what's possible with it?

The Cronfree Time Scheduler MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Cronfree Time Scheduler account. It provides structured and secure access so your agent can perform Cronfree Time Scheduler operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CRONFREE_TIME_SCHEDULER_CREATE_RECURRING_WEBHOOK_SCHEDULE` | Create Recurring Webhook Schedule | Create a Cronfree schedule that repeatedly POSTs to a webhook URL at times selected by weekday, month, month-day, hour, minute, and IANA timezone. |
| `CRONFREE_TIME_SCHEDULER_REMOVE_RECURRING_WEBHOOK_SCHEDULE` | Remove Recurring Webhook Schedule | Remove the Cronfree recurring schedule associated with a webhook URL. |

## Supported Triggers

None listed.

## 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) for the current limits that apply to your connection.

## Complete Code

None listed.

## Conclusion

### Use Cronfree Time Scheduler from Atomic Agent
With your account connected, ask Atomic Agent to work with Cronfree Time Scheduler in natural language. You can connect more apps through the same Composio integration as you need them.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Cronfree Time Scheduler MCP?

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

### Can I manage the permissions and scopes for Cronfree Time Scheduler while using Tool Router?

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