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 Higgsfield.

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

How Atomic Agent connects to Higgsfield

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

The Higgsfield MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Higgsfield account. It provides structured and secure access to Higgsfield image and video generation, so your agent can create images, produce videos, train character references, estimate costs, and track creative work on your behalf.

  • AI image creation: Have your agent generate images from text prompts with Soul Standard or Soul V2, choose available styles, or create images based on public reference images.
  • Text and image video generation: Direct your agent to produce Seedance 2.0 videos from written prompts or animate a publicly accessible starting image with DOP Lite.
  • Reusable character references: Let the agent train a Soul ID character reference from one or more public images and check when it is ready to use.
  • Cost planning and style selection: Instruct your agent to estimate the credit and USD cost of a Soul V2 Standard image before generation and review the styles available to your account.
  • Generation tracking and cancellation: Have your agent monitor image or video generation, collect completed media links, and cancel work that is still waiting in the queue.

Use Higgsfield from Atomic Agent

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

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

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