Polyxd MCP MCP server

An official MCP server by Polyxd that allows AI models to write, validate, and verify Polyxd UI documents. It renders these documents as real screens in various design-system packs and handles user interactions, enabling agents to generate and inspect UI components programmatically.

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 polyxd-mcp https://mcp.polyxd.com/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 polyxd-mcp --url https://mcp.polyxd.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable polyxd-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "polyxd-mcp": {
      "url": "https://mcp.polyxd.com/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": {
    "polyxd-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.polyxd.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start polyxd-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "polyxd-mcp": {
      "type": "http",
      "url": "https://mcp.polyxd.com/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 polyxd-mcp https://mcp.polyxd.com/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "polyxd-mcp": {
      "url": "https://mcp.polyxd.com/mcp"
    }
  }
}

Windsurf

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

Windsurf configuration

{
  "mcpServers": {
    "polyxd-mcp": {
      "serverUrl": "https://mcp.polyxd.com/mcp"
    }
