Point Cursor at the hosted MCP endpoint or run the open-source package locally — either way, marketplace search lands in your editor's AI.
Cursor supports MCP servers in its settings (Cursor Settings → MCP). You can add Secondhand MCP as a remote server (hosted, OAuth) or as a local stdio server via npx. Handy for price research without leaving your editor.
Takes about two minutes, once
Go to Cursor Settings → MCP → Add new MCP server (or edit ~/.cursor/mcp.json directly).
Add a remote server with URL https://secondhandmcp.com/mcp — Cursor will run the OAuth sign-in flow in your browser. Free tier included.

}Requires Node.js; add eBay API keys via an env block if you want eBay search.In Cursor's AI chat, ask something like "Find used 27-inch 4K monitors under $250 and summarize the best three."
Remote is simpler (no Node/Chrome needed, OAuth sign-in, free tier). Local is fully free and runs on your machine; Depop/Poshmark need Chrome installed.
Yes — Cursor handles remote MCP OAuth in the browser. Sign in once with email or Google and the connection persists.
Mostly convenience: price-checking parts and equipment, researching resale values, or scripting against structured listing data while you work.
