## 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 Documint.
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 Documint 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 Documint
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 Documint to Atomic Agent

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

The Documint MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Documint account. It provides structured and secure access to your Documint templates and documents, so your agent can list templates, fetch document details, update or delete templates, and manage your document workflows automatically.
- Template management and review: Quickly list all available templates or fetch details for a specific template to streamline document creation and organization.
- Automated template updates: Direct your agent to modify existing templates by updating settings or layouts, ensuring your documents always match your latest standards.
- Document listing and retrieval: Effortlessly list all documents in your account, making it easy to review, audit, or analyze your document library.
- Template cleanup and deletion: Have your agent permanently delete outdated or unused templates, keeping your workspace clutter-free and organized.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `DOCUMINT_CREATE_DOCUMENT` | Create Document | Tool to merge data into a template to create a document (PDF generation). Send JSON data with template variables in the request body to generate a PDF document. Returns a URL to the generated PDF (valid for 24 hours). |
| `DOCUMINT_DELETE_TEMPLATE` | Delete Template | Tool to permanently delete a single template by its ID. Use when you need to remove an outdated or unused template; ensure the template ID is correct before calling. |
| `DOCUMINT_GET_TEMPLATE` | Get Template | Tool to retrieve a single template by its ID. Use when you need to fetch details of a specific template before generating documents. |
| `DOCUMINT_LIST_DOCUMENTS` | List Documents | Retrieves documents from the authenticated user's Documint account with optional pagination. Returns a list of documents with their IDs, names, associated templates, and timestamps. Use this to view previously generated documents or to find document IDs for further operations. Supports page and limit parameters for paginated results. |
| `DOCUMINT_LIST_TEMPLATES` | List Templates | Tool to list all templates in the authenticated user's account. Use after obtaining a valid API key. |
| `DOCUMINT_UPDATE_TEMPLATE` | Update Template | Tool to update a single template by its ID. Use when you need to modify an existing template's settings or layout after fetching its current details. |

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

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

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

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