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": {
    "fal-mcp": {
      "command": "uvx",
      "args": [
        "fal-mcp-server"
      ]
    }
  }
}

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

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "fal-mcp": {
      "command": "uvx",
      "args": [
        "fal-mcp-server"
      ]
    }
  }
}

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": {
    "fal-mcp": {
      "command": "uvx",
      "args": [
        "fal-mcp-server"
      ]
    }
  }
}

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

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "fal-mcp": {
      "command": "uvx",
      "args": [
        "fal-mcp-server"
      ]
    }
  }
}

格式与 Claude Desktop 相同。重启 Windsurf 生效。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "fal-mcp",
      "command": "uvx",
      "args": [
        "fal-mcp-server"
      ]
    }
  ]
}

Continue 使用服务器对象数组，而非映射。

~/.config/zed/settings.json

{
  "context_servers": {
    "fal-mcp": {
      "command": {
        "path": "uvx",
        "args": [
          "fal-mcp-server"
        ]
      }
    }
  }
}

加入 context_servers。Zed 保存后热重载。

claude mcp add fal-mcp -- uvx fal-mcp-server

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

使用场景

实战用法： Fal.ai MCP

Turn a script into a narrated short with one prompt

👤 Marketers, indie creators ⏱ ~15 min intermediate

何时使用： You have a 30-second script and want a complete narrated short.

前置条件

Server/skill installed and authenticated — See repo README

步骤

Generate the scenes

Split this 30s script into 4 scenes and generate a video clip for each with Kling.✓ 已复制

→ Four video URLs
Narrate it

TTS each scene's narration with ElevenLabs Rachel voice.✓ 已复制

→ Audio URLs aligned with scenes

结果： Four video clips + matching narration audio, ready to stitch.

注意事项

Costs add up fast — Costs add up fast — set a hard budget in the prompt: 'Use the cheapest model that meets quality bar' and check the balance reported in tool output.

搭配使用： filesystem

组合

与其他 MCP 搭配，撬动十倍杠杆

fal-mcp + filesystem

Pair with filesystem for complementary capabilities

Use this server together with filesystem to complete a multi-step task.✓ 已复制
