Api Key

Cloudsmith is a cloud-native artifact management platform for software packages, containers, and dependencies. It helps teams securely store, distribute, and govern packages across repositories and environments.

10 Tools

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 Cloudsmith account to Claude via Composio Connect, enabling it to list recent packages in production repository, delete failed package versions after review, check Cloudsmith repository quota usage, 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.

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 Cloudsmith account

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

For example, ask Claude to:

  • "List recent packages in production repository"
  • "Delete failed package versions after review"
  • "Check Cloudsmith repository quota usage"

It will prompt you to authenticate and authorize access.

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

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

The Cloudsmith MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Cloudsmith account. It provides structured and secure access so your agent can perform Cloudsmith operations on your behalf.

Troubleshooting

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

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

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

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

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

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

3. Why does the Cloudsmith authorization link not work?

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

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

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

The Cloudsmith connection can expire or lose permission.

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

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

Claude can manage the Cloudsmith connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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