Add second-hand search to any agent

OpenClaw, Hermes, Manus, and anything else that can add an MCP server share this recipe. Nexthand is generic — not tied to Claude or ChatGPT. You add a server named nexthand, paste the MCP URL, reload the agent, then ask for used listings that can ship to you. If your config JSON looks different, keep that name and URL; only the wrapping object changes.

What you get

  • Your agent searches second-hand marketplaces, including ship-to-you filtering
  • Follow-ups in the same chat
  • Market watch: the same search, later
  • When you want an item, you open it on the marketplace it came from

What you need

An agent that can add an MCP server.

MCP is that plug. This page is the generic config, not a branded installer.

Add Nexthand

  1. Open your agent’s MCP settings or config file.
  2. Add a server named nexthand.
  3. Use your Nexthand MCP URL (replace the placeholder):
    {
      "mcpServers": {
        "nexthand": {
          "url": "YOUR_NEXTHAND_MCP_URL"
        }
      }
    }
  4. Reload the agent so it picks up the new server.

Verify

Ask the agent to search for something that can ship to you, for example: “Find me a used Canon EOS R6 under €1,200 that ships to Barcelona.”
