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 Countdown api account to Claude via Composio Connect, enabling it to list all your eBay data collections, start processing requests for a collection, get autocomplete suggestions for 'wireless earbuds', 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.

3. Connect your Countdown api account

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

For example, ask Claude to:

  • "List all your eBay data collections"
  • "Start processing requests for a collection"
  • "Get autocomplete suggestions for 'wireless earbuds'"

It will prompt you to authenticate and authorize access.

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

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

The Countdown api MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Countdown api account. It provides structured and secure access to real-time eBay marketplace data, so your agent can perform actions like searching eBay products, managing collections, retrieving seller feedback, and automating product data workflows on your behalf.

  • eBay product search and autocomplete: Instantly fetch eBay autocomplete suggestions and help agents surface relevant product search terms and ideas in real time.
  • Collection management and orchestration: Create, update, list, or delete collections to batch and organize multiple eBay data requests for streamlined marketplace analysis.
  • Automated collection processing: Start or clear queued requests within a collection, making it easy to control and automate data gathering operations from eBay.
  • Destination setup and notifications: Set up or remove destinations for results and notifications, ensuring your agent can manage where and how you receive processed eBay data.
  • Access to rich eBay metadata: Retrieve detailed collection information, product details, customer reviews, and seller feedback to power analytics and business decisions.

Troubleshooting

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

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

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

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

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

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

3. Why does the Countdown api authorization link not work?

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

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

4. Why do Countdown api actions fail after they worked before?

The Countdown api connection can expire or lose permission.

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

5. How do I switch to a different Countdown api account?

Claude can manage the Countdown api connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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