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 Kaleido account to Claude via Composio Connect, enabling it to list all API keys for your organization, create a new API key for our consortium, show all event streams configured in this environment, 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.

Add to Claude

Add manually

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

3. Connect your Kaleido account

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

For example, ask Claude to:

  • "List all API keys for your organization"
  • "Create a new API key for our consortium"
  • "Show all event streams configured in this environment"

It will prompt you to authenticate and authorize access.

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

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

The Kaleido MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Kaleido account. It provides structured and secure access to your blockchain environment, so your agent can perform actions like managing organizations, handling API keys, retrieving memberships, and monitoring event streams on your behalf.

  • Organization and consortium management: Let your agent list, retrieve, and manage organizations and consortia that you have access to—making it easy to keep your blockchain networks organized.
  • API key lifecycle control: Effortlessly create, retrieve, and delete API keys for your organization, so you can handle credential management without manual steps.
  • Membership and access insights: Quickly fetch details about user memberships and organizational access, helping you stay on top of roles and permissions in your blockchain environment.
  • Event stream monitoring: Retrieve and review all event streams configured in your environment, making it simple to keep tabs on real-time blockchain activity.
  • App2App and credential retrieval: Ask your agent to list App2App runtimes and fetch application credentials for specific environments, streamlining application integration and deployment.

Troubleshooting

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

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

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

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

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

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

3. Why does the Kaleido authorization link not work?

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

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

4. Why do Kaleido actions fail after they worked before?

The Kaleido connection can expire or lose permission.

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

5. How do I switch to a different Kaleido account?

Claude can manage the Kaleido connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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