Overview

Lark MCP Server is a Model Context Protocol (MCP) server implementation designed for Lark/Feishu, enabling MCP-compatible applications to interact with Lark's collaboration capabilities.

To use Lark MCP Server, clone the repository, install dependencies, and build the project. Connect it with an MCP client like Claude Desktop by configuring the necessary settings in the claude_desktop_config.json file.

  • Message Sending: Allows AI models to send direct messages to Lark users. - Calendar Management: - List events within a specific time range. - Create new calendar events with customizable details. - Add various types of attendees to events (users, groups, meeting rooms, external emails).
  1. Integrating AI assistants with Lark for enhanced communication.
  2. Automating calendar event management through AI models.
  3. Facilitating real-time messaging between AI applications and Lark users.

Add to your AI client

Use these steps to connect Lark MCP Server in Cursor, Claude, VS Code, and other MCP-compatible apps. The same JSON appears in the Use with menu above for one-click copy.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "lark-mcp-server-junyuan-qi": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-lark-mcp-server-junyuan-qi"
      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "lark-mcp-server-junyuan-qi": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-lark-mcp-server-junyuan-qi"
      ]
    }
  }
}

Claude Code

Add this to your project's .mcp.json file. Claude Code will detect it automatically.

.mcp.json (project root)

{
  "mcpServers": {
    "lark-mcp-server-junyuan-qi": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-lark-mcp-server-junyuan-qi"
      ]
    }
  }
}

VS Code (Copilot)

Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

.vscode/mcp.json

{
  "servers": {
    "lark-mcp-server-junyuan-qi": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-lark-mcp-server-junyuan-qi"
      ]
    }
  }
}

Windsurf

Add this to your Windsurf MCP config file, then restart Windsurf.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "lark-mcp-server-junyuan-qi": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-lark-mcp-server-junyuan-qi"
      ]
    }
  }
}

Cline

Open Cline settings, navigate to MCP Servers, and add this server configuration.

Cline MCP Settings (via UI)

{
  "mcpServers": {
    "lark-mcp-server-junyuan-qi": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-lark-mcp-server-junyuan-qi"
      ]
    }
  }
}
