Market0x MCP MCP server

Market0x provides a non-custodial Model Context Protocol server that enables autonomous agents to interact with its marketplace for vote-escrow NFTs and .base.eth names. Agents can read live listings, prepare purchases, bids, and listings, and manage notifications, with all transactions settling on-chain via Seaport without the server holding user keys.

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

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 market0x-mcp https://www.market0x.com/api/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 market0x-mcp --url https://www.market0x.com/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable market0x-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "market0x-mcp": {
      "url": "https://www.market0x.com/api/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.
Cline configuration
{
  "mcpServers": {
    "market0x-mcp": {
      "type": "streamableHttp",
      "url": "https://www.market0x.com/api/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start market0x-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "market0x-mcp": {
      "type": "http",
      "url": "https://www.market0x.com/api/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http market0x-mcp https://www.market0x.com/api/mcp

Claude Desktop

    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

  "mcpServers": {
    "market0x-mcp": {
      "serverUrl": "https://www.market0x.com/api/mcp"
