## 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 Sendloop.
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 Sendloop 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 Sendloop
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 Sendloop to Atomic Agent

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

The Sendloop MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Sendloop account. It provides structured and secure access to your email marketing campaigns, subscriber lists, and detailed reports, so your agent can list campaigns, analyze subscriber data, retrieve account information, and review campaign performance on your behalf.
- Comprehensive campaign management: Ask your agent to list all existing email campaigns, filter them by status, and handle pagination to easily browse through your marketing efforts.
- Subscriber list access and reporting: Retrieve all your mailing lists and get detailed reports on subscriber growth, engagement, and performance after sending campaigns.
- Targeted subscriber insights: Let the agent fetch subscribers for any given list, filter them by status, and manage large lists with effortless pagination.
- Account information retrieval: Have your agent pull up-to-date details about your Sendloop account, keeping you informed about your overall setup and usage.
- Performance analytics: Quickly get summary metrics for specific subscriber lists to evaluate campaign success and optimize your email marketing strategy.

## Supported Tools

| Tool slug | Name | Description |

| `SENDLOOP_GET_OVERALL_LIST_REPORT` | Get Overall List Report | Tool to retrieve overall report for a subscriber list. Use after sending campaigns to get summary metrics. |
| `SENDLOOP_LIST_CAMPAIGNS` | List Campaigns | Tool to list campaigns. Use when you need to filter by campaign status and handle pagination for campaign retrieval. |
| `SENDLOOP_LIST_LISTS` | List SendLoop Lists | Tool to retrieve subscriber lists. Use when you need to get all mailing lists. |
| `SENDLOOP_LIST_SUBSCRIBERS` | List SendLoop Subscribers | Tool to list subscribers in a specified SendLoop list with pagination. Use when you need to retrieve subscribers for a given list ID, optionally filtering by segment and using start index for pagination. |

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

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

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

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