How to integrate Feathery MCP with Atomic Agent

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 Feathery.

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

How Atomic Agent connects to Feathery

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 Feathery 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 Feathery. It searches Composio for the right tool.
4. On first use, open the sign-in link returned in the chat. Connect your Feathery 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.

The Feathery MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Feathery account. It provides structured and secure access to your forms and workflow data, so your agent can perform actions like creating hidden fields, retrieving form schemas, listing documents, and managing account settings on your behalf.

• Form discovery and management: Let your agent list all existing forms, retrieve specific form schemas, or permanently remove forms as needed.
• Document automation and signing: Automatically fill or sign document templates and track generated document envelopes for streamlined data processing.
• Hidden field configuration: Create new hidden fields or list all hidden fields within your forms for advanced workflow logic and data capture.
• Account and team management: Fetch detailed account info, update user roles and permissions, and manage your Feathery team's access seamlessly.
• Integration troubleshooting: List recent API connector errors tied to specific forms, making it easier to debug and maintain your integrations.

Use Feathery from Atomic Agent

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