What its tools let an agent do: 5 read

Install Secondhand in Claude Code, Cursor or VS Code

Runs npx -y secondhand-mcp on your machine. Read the scan report first; the gateway never runs local packages.

Secondhand MCP

A Model Context Protocol (MCP) server that lets AI assistants search secondhand marketplaces. Search Facebook Marketplace, eBay, Depop, and Poshmark for used and secondhand items — filter by price, category, condition, size, and color, then get full listing details with photos, descriptions, and seller info.

Works with Claude Desktop, Claude Code, Cursor, and other clients that run MCP servers locally.

[!TIP]

Using ChatGPT? This one won't work there.

It runs on your computer, so it only works where your computer is — Claude Desktop, Claude Code, Cursor. Secondhand MCP Cloud is the same search, always on, so whichever assistant you actually use can reach it. Free tier, no card.

Supported Marketplaces

Setup

Claude Desktop

Add to ~/Library/Application Support/Claude/claudedesktopconfig.json:

{
  "mcpServers": {
    "secondhand": {
      "command": "npx",
      "args": ["-y", "secondhand-mcp"],
      "env": {
        "EBAY_CLIENT_ID": "your-ebay-client-id",
        "EBAY_CLIENT_SECRET": "your-ebay-client-secret",
        "EBAY_MARKETPLACE_ID": "EBAY_US"
      }
    }
  }
}

Claude Code

Add to ~/.claude/.mcp.json:

{
  "mcpServers": {
    "secondhand": {
      "command": "npx",
      "args": ["-y", "secondhand-mcp"],
      "env": {
        "EBAY_CLIENT_ID": "your-ebay-client-id",
        "EBAY_CLIENT_SECRET": "your-ebay-client-secret",
        "EBAY_MARKETPLACE_ID": "EBAY_US"
      }
    }
  }
}

eBay, Depop, and Poshmark are all optional — if eBay API keys are missing or Chrome isn't installed, those marketplaces are automatically disabled and the rest still work.

Depop & Poshmark / Chrome Requirement

Depop and Poshmark require a headless browser. If Google Chrome or Chromium is installed on your system, both are automatically enabled — no config needed. If Chrome isn't found, they are silently skipped.

On macOS, the first time you search Depop or Poshmark, you may see a system prompt asking to allow Node.js to control Chrome. This is expected — puppeteer needs to launch Chrome in headless mode. Allow it once and it won't ask again.

The browser runs invisibly in the background and only launches when you actually search Depop or Poshmark.

Configuration

Choosing Marketplaces

By default all marketplaces are enabled. To limit which are active, set the MARKETPLACES env var (comma-separated):

{
  "env": {
    "MARKETPLACES": "facebook,ebay"
  }
}

Valid values: facebook, ebay, depop, poshmark

eBay API Keys

eBay uses the official Browse API. You need a free eBay developer account:

  1. Create an account at developer.ebay.com
  2. Create an application to get a Client ID and Client Secret
  3. Add them to your MCP config as EBAYCLIENTID and EBAYCLIENTSECRET
