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 Stytch.

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

How Atomic Agent connects to Stytch

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 Stytch to Atomic Agent

Sign up or sign in to the Composio dashboard. 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 Stytch. It searches Composio for the right tool.
On first use, open the sign-in link returned in the chat. Connect your Stytch 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 Stytch MCP server, and what's possible with it?

The Stytch MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Stytch account. It provides structured and secure access to your projects and workspace settings, so your agent can create projects, manage redirect URLs, configure SDK and password settings, maintain email templates, and manage project credentials on your behalf.

Project management: Have your agent create new Stytch projects or list your existing projects.
Redirect URL configuration: Direct your agent to list, create, update, or delete redirect URLs for a project.
Authentication settings: Let the agent retrieve or update Consumer and B2B SDK settings, and review or set password strength requirements.
Email template management: Instruct your agent to list, create, update, or delete custom email templates for a project.
Project credential management: Have your agent create, list, or delete public tokens, and create or delete project secrets.

Use Stytch from Atomic Agent

With your account connected, ask Atomic Agent to work with Stytch 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 Stytch MCP server, the agents and LLMs can only access a fixed set of Stytch tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Stytch 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 Stytch tools.

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