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 any MCP-compatible client.

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.
