Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Test app account to Claude via Composio Connect, enabling it to run action one with sample input, execute action two for test workflow, trigger action one for current user, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

Connecting Test app to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash

https://connect.composio.dev/mcp

Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Test app account

Back in Claude, ask it to connect to Test app or give it any Test app-related task.

For example, ask Claude to:

"Run action one with sample input"
"Execute action two for test workflow"
"Trigger action one for current user"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Test app account is ready to use.

What is the Test app Claude Connector, 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.

Troubleshooting

1. Why does Claude not use the Composio connector for Test app?

The connector can show as connected, but Claude must use it in each Test app conversation.

Click + at the lower left of the chat, or type /.
Hover Connectors.
Turn on Composio.
Ask Claude to connect to Test app again.

2. Why does Claude show an MCP server error before Test app connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Test app.

Check that the connector URL is https://connect.composio.dev/mcp.
Connectors run from Anthropic's cloud, so your device network is usually not the problem.
Add the connector again from Customize > Connectors, then ask Claude to connect Test app.
If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Test app authorization link not work?

The Composio connector is one server. Your Test app account connects separately when Claude asks for it.

If the browser does not open, or the link expires, ask Claude to retry the Test app connection.
Composio creates a fresh Test app authorization link.
Open that link in your browser and finish the Test app sign-in.

4. Why do Test app actions fail after they worked before?

The Test app connection can expire or lose permission.

Ask Claude to inspect the Test app connection.
If the connection is unhealthy, disconnect it when Claude prompts you.
Reconnect the Test app account and retry the action.
If Claude shows a permission prompt, approve it before Claude changes data in Test app.
If the action still fails with a permission error, check that the connected account has that permission in Test app itself.

5. How do I switch to a different Test app account?

Claude can manage the Test app connection for you.

Ask Claude to disconnect or delete the current Test app account.
Ask Claude to connect Test app again.
Open the new Composio authorization link for Test app.
Sign in with the other Test app account in the browser.
After the account connects, ask Claude to retry the Test app task.

6. Why is my Test app connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Test app connection works in Claude Web, Desktop, and Cowork.

In Claude Desktop, open Customize > Connectors.
Next to Composio, click ⋮ and click Clear cache.
If Test app tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Test app.

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. Claude Cowork 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.
