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 AWS Marketplace account to Claude via Composio Connect, enabling it to find security tools with free trials, compare Kubernetes monitoring marketplace listings, shortlist data products for analytics teams, 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.

4. Connect your AWS Marketplace account

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

For example, ask Claude to:

  • "Find security tools with free trials"
  • "Compare Kubernetes monitoring marketplace listings"
  • "Shortlist data products for analytics teams"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the AWS Marketplace authorization link not work?

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

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

4. Why do AWS Marketplace actions fail after they worked before?

The AWS Marketplace connection can expire or lose permission.

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

5. How do I switch to a different AWS Marketplace account?

Claude can manage the AWS Marketplace connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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