## 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 Files com.
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 Files com 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 Files com
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 Files com to Atomic Agent

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

The Files.com MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Files.com account. It provides structured and secure access to your cloud storage and file management resources, so your agent can perform actions like listing folders, managing permissions, generating upload keys, and handling file shares on your behalf.
- Folder navigation and organization: Ask your agent to list and explore folders within your Files.com account, making it easy to locate and organize files.
- Permission management: Allow the agent to retrieve, review, and delete access permissions for files or folders, keeping your data secure and access controlled.
- Secure file uploading: Have your agent generate S3 upload keys so you can temporarily host files for easy import, sharing, or collaboration across teams.
- Group and share link management: Let your agent list user groups or delete share links to efficiently manage who has access to important documents and shared resources.
- API key lifecycle control: Instruct your agent to revoke API keys when needed, ensuring only authorized integrations remain active for your account.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `FILES_COM_DELETE_API_KEY` | Delete API Key | Tool to delete an API key. Use when you need to revoke an API key after confirming its identifier. |
| `FILES_COM_DELETE_PERMISSION` | Delete Permission | Removes a permission grant that allows a user or group to access a specific file or folder path on Files.com. A permission ID can be obtained from the LIST_PERMISSIONS action. Use this tool when you need to revoke access that was previously granted to a user or group for a specific resource. Note: Requires administrative permissions on the Files.com site. |
| `FILES_COM_DELETE_SHARE` | Delete Share | Delete a specified share link (bundle) on Files.com. This operation is idempotent - it succeeds even if the share link has already been deleted or doesn't exist. Use this to revoke public access to shared files/folders when you have the share ID. |
| `FILES_COM_GET_S3_KEY_FOR_UPLOAD` | Get S3 Key for Upload | Tool to generate a temporary key for file uploads by uploading the file to Files.com. Useful when you need to host a local file temporarily before importing or sharing. |
| `FILES_COM_LIST_FOLDERS` | List Folders | Lists folders in Files.com with optional filtering, sorting, and pagination. Returns a paginated list of folders with metadata. Useful for browsing folder structure, finding specific folders by name, or retrieving folders under a specific parent. |
| `FILES_COM_LIST_GROUPS` | List Groups | Retrieves a paginated list of all groups from Files.com. Groups are used to organize users and manage permissions collectively. Use this action to discover available groups, check group membership, or before performing group-based permission operations. Returns group details including IDs, names, member lists, and access permissions (FTP, SFTP, WebDAV, REST API). |
| `FILES_COM_LIST_PERMISSIONS` | List Permissions | Retrieve permissions for a specified path on Files.com. Use when you need to inspect who has access and what level for a given file or folder path. |

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

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

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

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