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 Black Forest Labs.

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 Black Forest Labs account. See the Atomic Agent documentation for installation instructions.

How Atomic Agent connects to Black Forest Labs

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

The Black Forest Labs MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Black Forest Labs account. It provides structured and secure access to hosted FLUX image and video tools, so your agent can generate and edit images, create and transform videos, manage fine-tunes, and check project credits on your behalf.

  • Image generation and editing: Have your agent create FLUX images from prompts, edit reference images, erase unwanted objects, expand images beyond their original canvas, deblur them, or generate images with an existing fine-tune.
  • Video creation and transformation: Direct your agent to generate videos from text or source materials, edit existing videos with a prompt, or upscale videos by a selected amount.
  • Virtual try-on experiences: Let the agent combine authorized person and garment images to create virtual try-on results.
  • Generation progress and results: Instruct your agent to check the status of image or video tasks and retrieve their completed results.
  • Fine-tune and credit management: Have your agent review available fine-tunes, inspect a specific fine-tune, and check the project's current credit balance before paid generation or editing work.

Use Black Forest Labs from Atomic Agent

With your account connected, ask Atomic Agent to work with Black Forest Labs 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.

FAQ

Frequently asked questions

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

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