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 Kraken io account to Claude via Composio Connect, enabling it to compress this product image from its URL, check your Kraken.io API quota usage, optimize image while keeping all EXIF data, 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 Kraken io 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 Kraken io account

Back in Claude, ask it to connect to Kraken io or give it any Kraken io-related task.

For example, ask Claude to:

  • "Compress this product image from its URL"
  • "Check your Kraken.io API quota usage"
  • "Optimize image while keeping all EXIF data"

It will prompt you to authenticate and authorize access.

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

What is the Kraken io Claude Connector, and what's possible with it?

The Kraken io MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Kraken io account. It provides structured and secure access to your image optimization tools, so your agent can automatically compress images, resize or convert files, monitor account usage, and test optimizations without consuming real credits.

  • Real-time image optimization by URL: Instantly compress, resize, or convert images hosted on public URLs—perfect for streamlining website performance or social media workflows.
  • Quota and account status monitoring: Let your agent check your Kraken.io plan limits, remaining quota, and current account status before processing images, so you never hit a surprise limit.
  • Metadata preservation during compression: Instruct your agent to optimize images while keeping essential EXIF and metadata intact, making sure important information stays with your files.
  • Sandbox image upload and testing: Safely upload and optimize images in sandbox mode, allowing you to test settings and workflows without using up your actual credits.

Troubleshooting

1. Why does Claude not use the Composio connector for Kraken io?

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

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

2. Why does Claude show an MCP server error before Kraken io connects?

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

  • 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 Kraken io.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Kraken io authorization link not work?

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

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

4. Why do Kraken io actions fail after they worked before?

The Kraken io connection can expire or lose permission.

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

5. How do I switch to a different Kraken io account?

Claude can manage the Kraken io connection for you.

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

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

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

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Kraken io 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 Kraken io.

FAQ

Frequently asked questions

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

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