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 CrewAI.

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 CrewAI account. See the Atomic Agent documentation for installation instructions.

How Atomic Agent connects to CrewAI

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 CrewAI to Atomic Agent

  1. Sign up or sign in to the Composio dashboard. Copy your API key.
  2. 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.
  3. Ask Atomic Agent to do something in CrewAI. It searches Composio for the right tool.
  4. On first use, open the sign-in link returned in the chat. Connect your CrewAI 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 CrewAI MCP server, and what's possible with it?

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

Use CrewAI from Atomic Agent

With your account connected, ask Atomic Agent to work with CrewAI in natural language. You can connect more apps through the same Composio integration as you need them.

Visit the Atomic Agent website or inspect the Atomic Agent source code.

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 for the current limits that apply to your connection.

TOOLS

Supported Tools

Every CrewAI action and event your agent gets out of the box.

Get Deployment Logs

Return deployment lifecycle logs for a CrewAI deployment UUID to diagnose build or runtime deployment failures.

Get Deployment Status

Return the current AMP deployment status for one crew UUID from the SaaS control plane.

Get Execution Status

Return the current state, progress, result, or error for a deployed-crew execution started with a kickoff ID.

Get Required Inputs

Return the input names required by the connected deployed CrewAI automation before starting an execution.

List Crew Deployments

List CrewAI crew deployments visible to the selected SaaS organization and return their identifiers for status, logs, or redeployment.

Redeploy Crew

Trigger a new deployment of an existing CrewAI automation by UUID; this irreversibly changes the live deployment and may replace its runtime URL or token.

Resume Crew Execution

Approve or retry a human-in-the-loop task and resume its paused CrewAI execution.

Start Crew Execution

Start one execution of the connected deployed CrewAI automation and return its kickoff ID for status checks.

FAQ

Frequently asked questions

With a standalone CrewAI MCP server, the agents and LLMs can only access a fixed set of CrewAI tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from CrewAI and many other apps based on the task at hand, all through a single MCP endpoint.

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 CrewAI tools.

Yes, absolutely. You can configure which CrewAI 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.

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 CrewAI data and credentials are handled as safely as possible.
