## 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 Moonclerk.
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 Moonclerk 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 Moonclerk
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 Moonclerk to Atomic Agent

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

The Moonclerk MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Moonclerk account. It provides structured and secure access to your Moonclerk data, so your agent can perform actions like listing customers, tracking payments, reviewing subscriptions, and analyzing discounts on your behalf.
- Comprehensive customer listing: Retrieve and filter your Moonclerk customer records, making it easy to access up-to-date client data and plan details.
- Detailed payment tracking: Ask your agent to list all payments or filter them by form, customer, time frame, or payment status—perfect for quick financial overviews.
- Subscription management and review: Effortlessly get a full rundown of all active, paused, or cancelled subscriptions associated with your business.
- Payment form overview: Have your agent fetch a complete list of your payment forms, helping you audit, review, or analyze available checkout options in seconds.
- Discount analytics: Instantly pull details on all discounts applied to customers, so you can monitor promotional effectiveness and customer engagement.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|

| `MOONCLERK_LIST_DISCOUNTS` | List Discounts | Tool to retrieve a list of all discounts applied to customers. Use after authenticating API credentials. |
| `MOONCLERK_LIST_FORMS` | List Payment Forms | Tool to retrieve a list of all payment forms. Use after authenticating to inspect available payment forms. |
| `MOONCLERK_LIST_PAYMENTS` | List Payments | Tool to list payments. Use when you need to retrieve all payments or filter by form, customer, date range, or status after authenticating. |
| `MOONCLERK_LIST_SUBSCRIPTIONS` | List Subscriptions | Tool to list subscriptions. Use when you need to retrieve all subscriptions after authenticating. |

## 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 Moonclerk from Atomic Agent
With your account connected, ask Atomic Agent to work with Moonclerk 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 Moonclerk MCP?

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

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

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