Connect Secondhand MCP to Cursor

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.

Setup steps

Takes about two minutes, once

  1. Open Cursor's MCP settings

    Go to Cursor Settings → MCP → Add new MCP server (or edit ~/.cursor/mcp.json directly).

  2. Option A — hosted (remote)

    Add a remote server with URL https://secondhandmcp.com/mcp — Cursor will run the OAuth sign-in flow in your browser. Free tier included.

    {
      "mcpServers": {
        "secondhand": {
          "url": "https://secondhandmcp.com/mcp"
        }
      }
    }

  3. Option B — local (npx)

    {
      "mcpServers": {
        "secondhand": {
          "command": "npx",
          "args": ["-y", "secondhand-mcp"]
        }
      }
    }
    Requires Node.js; add eBay API keys via an env block if you want eBay search.

  4. Use it in chat

    In Cursor's AI chat, ask something like "Find used 27-inch 4K monitors under $250 and summarize the best three."

Frequently asked questions

Remote or local for Cursor?

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.

Does Cursor support the OAuth flow?

Yes — Cursor handles remote MCP OAuth in the browser. Sign in once with email or Google and the connection persists.

Why would I search marketplaces from my editor?

Mostly convenience: price-checking parts and equipment, researching resale values, or scripting against structured listing data while you work.
