Open WebUI

Name: Open WebUI MCP Server
Author: open-webui

Self-hosted ChatGPT-like UI with MCP support — point it at Ollama or any provider and consume MCP tools through a real web app.

Open WebUI is the most-used self-hosted chat UI. It supports MCP servers as tools, so you can run Claude-style workflows on your hardware. Useful when you need a multi-user UI in front of MCP that isn't Claude Desktop.

安装

选择你的客户端

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "open-webui-mcp": {
      "command": "docker",
      "args": [
        "run",
        "-p",
        "3000:8080",
        "ghcr.io/open-webui/open-webui:main"
      ]
    }
  }
}

打开 Claude Desktop → Settings → Developer → Edit Config。保存后重启应用。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "open-webui-mcp": {
      "command": "docker",
      "args": [
        "run",
        "-p",
        "3000:8080",
        "ghcr.io/open-webui/open-webui:main"
      ]
    }
  }
}

Cursor 使用与 Claude Desktop 相同的 mcpServers 格式。项目级配置优先于全局。

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "open-webui-mcp": {
      "command": "docker",
      "args": [
        "run",
        "-p",
        "3000:8080",
        "ghcr.io/open-webui/open-webui:main"
      ]
    }
  }
}

点击 Cline 侧栏中的 MCP Servers 图标，然后选 "Edit Configuration"。

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "open-webui-mcp": {
      "command": "docker",
      "args": [
        "run",
        "-p",
        "3000:8080",
        "ghcr.io/open-webui/open-webui:main"
      ]
    }
  }
}

格式与 Claude Desktop 相同。重启 Windsurf 生效。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "open-webui-mcp",
      "command": "docker",
      "args": [
        "run",
        "-p",
        "3000:8080",
        "ghcr.io/open-webui/open-webui:main"
      ]
    }
  ]
}

Continue 使用服务器对象数组，而非映射。

~/.config/zed/settings.json

{
  "context_servers": {
    "open-webui-mcp": {
      "command": {
        "path": "docker",
        "args": [
          "run",
          "-p",
          "3000:8080",
          "ghcr.io/open-webui/open-webui:main"
        ]
      }
    }
  }
}

加入 context_servers。Zed 保存后热重载。

claude mcp add open-webui-mcp -- docker run -p 3000:8080 ghcr.io/open-webui/open-webui:main

一行命令搞定。用 claude mcp list 验证，claude mcp remove 卸载。
