How to integrate Test app MCP with Atomic Agent

Connect Atomic Agent to Test app MCP. Run action one with sample input, execute action two for test workflow, and more using natural language, with authentication handled for you.

Test app is a developer utility designed for testing messaging and workflow automations. It makes it easy to simulate, monitor, and debug complex agent-driven flows.

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 Test app.

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 Test app account. See the Atomic Agent documentation for installation instructions.

How Atomic Agent connects to Test app

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

The Test app MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Test app account. It provides structured and secure access to your Test app tools, so your agent can perform actions like running automated tasks, triggering custom actions, and combining multiple app features on your behalf.

  • Execute Action One instantly: Direct your agent to perform the "Action one" operation, automating key Test app workflows without manual intervention.
  • Trigger Action Two seamlessly: Instruct your agent to initiate "Action two" whenever you need, making it easy to manage repetitive or complex processes.
  • Combine multiple Test app operations: Let your agent chain together both "Action one" and "Action two" for multi-step automation, all in a single request.
  • Streamline repetitive tasks: Offload routine actions to your agent, boosting efficiency and reducing manual errors within Test app.

Use Test app from Atomic Agent

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

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