## 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 eBay account to Claude via Composio Connect, enabling it to find refurbished laptops under $500, compare sold prices for vintage cameras, explore categories 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.

## What is the eBay MCP server, and what's possible with it?

The eBay MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your eBay account. It provides structured and secure access to eBay marketplace, category, deal, notification, translation, and developer analytics data, so your agent can search listings, compare item details, discover deals, classify products, and translate listing content on your behalf.
- Marketplace listing research: Have your agent search eBay by keywords, categories, product details, or images, then retrieve complete information for selected listings and product variations.
- Deals and product discovery: Let the agent find current deal events, browse discounted items, and surface best-selling products by category, marketplace, and delivery country.
- Category and listing enrichment: Direct your agent to suggest the right eBay category, identify required item details, review valid category values, and check vehicle compatibility properties for parts listings.
- Localization and charitable shopping: Instruct your agent to translate listing titles or descriptions and find eBay-supported charitable organizations by name or registration details.
- Notifications and API monitoring: Have your agent review available notification topics, retrieve public keys for validating eBay notifications, and check application usage limits and reset windows.

## Troubleshooting

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

The connector can show as connected, but Claude must use it in each eBay conversation.
- Click + at the lower left of the chat, or type /.
- Hover Connectors.
- Turn on Composio.
- Ask Claude to connect to eBay again.

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

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for eBay.
- 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 eBay.
- If it fails again, send the error and the ofid_ reference id to support@composio.dev.

### 3. Why does the eBay authorization link not work?

The Composio connector is one server. Your eBay account connects separately when Claude asks for it.
- If the browser does not open, or the link expires, ask Claude to retry the eBay connection.
- Composio creates a fresh eBay authorization link.
- Open that link in your browser and finish the eBay sign-in.

### 4. Why do eBay actions fail after they worked before?

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

### 5. How do I switch to a different eBay account?

Claude can manage the eBay connection for you.
- Ask Claude to disconnect or delete the current eBay account.
- Ask Claude to connect eBay again.
- Open the new Composio authorization link for eBay.
- Sign in with the other eBay account in the browser.
- After the account connects, ask Claude to retry the eBay task.

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

The connector belongs to your Claude account, so your eBay connection works in Claude Web, Desktop, and Cowork.
- In Claude Desktop, open Customize > Connectors.
- Next to Composio, click ⋮ and click Clear cache.
- If eBay 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 eBay.

## Creating MCP Server - Stand-alone vs Composio SDK

The eBay MCP server connects Claude Web, Desktop, and Cowork to your eBay account through Composio. Once connected, Claude can use the available eBay tools and triggers to complete tasks on your behalf.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and eBay MCP?

With a standalone eBay MCP server, the agents and LLMs can only access a fixed set of eBay tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from eBay and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Claude Cowork?

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 eBay tools.

### Can I manage the permissions and scopes for eBay while using Tool Router?

Yes, absolutely. You can configure which eBay 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.

### How safe is my data with Composio Tool Router?

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 eBay data and credentials are handled as safely as possible.
