## 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 Are.na.
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 Are.na account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.

## Also integrate Are.na with

- [ChatGPT](https://composio.dev/toolkits/arena/framework/chatgpt)
- [Claude Cowork](https://composio.dev/toolkits/arena/framework/claude-cowork)
- [Hermes](https://composio.dev/toolkits/arena/framework/hermes-agent)

## TL;DR

### How Atomic Agent connects to Are.na
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 Are.na to Atomic Agent

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

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

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `ARENA_ADD_TO_CHANNELS` | Add To Channels | Add an existing Are.na block or channel to one or more target channels without duplicating the underlying resource. |
| `ARENA_CREATE_CHANNEL` | Create Channel | Create a user-owned Are.na channel, closed by default, and return its stable numeric ID and generated slug. |
| `ARENA_DELETE_CHANNEL` | Delete Channel | Permanently delete one Are.na channel the authenticated user is allowed to destroy. This cannot be undone. |
| `ARENA_GET_BLOCK` | Get Block | Get the details of one Are.na block by ID, including its subtype, content, source, creator, and metadata. |
| `ARENA_GET_CHANNEL` | Get Channel | Get an Are.na channel by numeric ID or slug, including visibility, counts, owner, and the current user's permissions. |
| `ARENA_GET_CURRENT_USER` | Get Current User | Return the identity and account details for the authenticated Are.na user. |
| `ARENA_GET_MY_FEED` | Get My Feed | Return one page of the authenticated user's personalized Are.na activity feed, newest first. Call again with next_cursor only when another page is needed. |
| `ARENA_LIST_CHANNEL_CONTENTS` | List Channel Contents | Return one page of blocks and nested channels from an Are.na channel, with optional sorting and contributor filtering. |
| `ARENA_REMOVE_FROM_CHANNEL` | Remove From Channel | Remove one block or nested channel placement from an Are.na channel. This deletes only the connection; the underlying block or channel remains intact and may still exist in other channels. |
| `ARENA_UPDATE_CHANNEL` | Update Channel | Update selected fields of an Are.na channel the authenticated user can edit. Fields omitted from the request remain unchanged. |

## 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.

## Conclusion

### Use Are.na from Atomic Agent
With your account connected, ask Atomic Agent to work with Are.na 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 Are.na MCP?

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

### Can I manage the permissions and scopes for Are.na while using Tool Router?

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