## 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 Common Room.
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 Common Room 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 Common Room
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 Common Room MCP to Atomic Agent

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

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

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `COMMON_ROOM_MCP_COMMONROOM_CREATE_OBJECT` | Commonroom create object | Writes a new contact, organization, segment, activity, note or tag to Common Room. Contacts and organizations are upserts, so this both creates and merges into an existing record; use commonroom_update_object instead when editing a record you have already identified. Look up the IDs and existing values it needs with commonroom_list_objects, and the writable fields for each type with commonroom_get_catalog. |
| `COMMON_ROOM_MCP_COMMONROOM_GET_CATALOG` | Commonroom get catalog | Reports which object types this workspace exposes and, for each, the fields it can be filtered by, the properties it can return, the fields it can be sorted by, and the other objects it is associated with. Call it before commonroom_list_objects, commonroom_create_object or commonroom_update_object: field names vary by workspace, so building a filter or a write from guessed names fails. |
| `COMMON_ROOM_MCP_COMMONROOM_LIST_OBJECTS` | Commonroom list objects | Reads Common Room records — contacts, organizations, activities, segments and custom objects — as a filtered, sorted, paginated list, or fetches one record by ID. Call commonroom_get_catalog first: it reports which object types exist and which fields each one can be filtered, sorted and returned by. Also use this tool to look up the values other filters expect, such as role names, Bombora topics and location IDs. Use commonroom_create_object or commonroom_update_object to write records; this tool only reads. |
| `COMMON_ROOM_MCP_COMMONROOM_SUBMIT_FEEDBACK` | Commonroom submit feedback | Records the user's verdict on results returned by a previous Common Room query. Call it after presenting data, when the user says the results were helpful, says they were wrong or incomplete, or comments on the data quality. It stores feedback only — it neither re-runs the query nor changes any record. |
| `COMMON_ROOM_MCP_COMMONROOM_UPDATE_OBJECT` | Commonroom update object | Edits an existing contact, organization, custom-object record or segment, identified by its ID. Every change is a partial update: omitted fields keep their current values and tag changes apply only to the tags listed. Use commonroom_create_object when the record may not exist yet, since that upserts contacts and organizations; use commonroom_list_objects to find the ID to pass here and commonroom_get_catalog for which fields are mutable. |

## 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

## Conclusion

### Use Common Room from Atomic Agent
With your account connected, ask Atomic Agent to work with Common Room 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 Common Room MCP?

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

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

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