ForSale MCP

An MCP server that enables AI agents to negotiate prices on Shopify products. It allows agents to search for offerable items, make offers, respond to counters, and generate single-use checkout codes, effectively acting as a negotiation layer for AI shoppers.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http forsale-mcp https://mcp.forsale.xyz/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add forsale-mcp --url https://mcp.forsale.xyz/mcp

      "url": "https://mcp.forsale.xyz/mcp"
    }
  }
}

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

    "forsale-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.forsale.xyz/mcp",
