Feishu/Lark MCP server for AI agents

The Feishu/Lark OpenAPI MCP server allows you to quickly connect AI agents to the Feishu/Lark platform, enabling them to access and manipulate data through Feishu/Lark APIs. This tool encapsulates various Feishu/Lark features including messaging, document operations, calendar management, and more.

Prerequisites

Creating a Feishu/Lark Application

Before using lark-mcp, you'll need to:

Visit the Feishu Open Platform or Lark Open Platform and log in
Click "Console" to create a new application
Obtain the App ID and App Secret for authentication
Add the necessary permissions for your application
Set up OAuth 2.0 redirect URLs if you need user access tokens

Installing Node.js

On macOS

# Using Homebrew
brew install node

# Verify installation
node -v
npm -v

On Windows

Download and install from Node.js website or use nvm-windows:

# After installing nvm-windows
nvm install latest
nvm use <version_number>

Installation

Install the lark-mcp tool globally:

npm install -g @larksuiteoapi/lark-mcp

Basic Usage

Integration with AI Tools (Trae/Cursor/Claude)

Add this to your AI tool configuration file:

{
  "mcpServers": {
    "lark-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@larksuiteoapi/lark-mcp",
        "mcp",
        "-a",
        "<your_app_id>",
        "-s",
        "<your_app_secret>"
      ]
    }
  }
}

To use with user identity:

{
  "mcpServers": {
    "lark-mcp": {
     "command": "npx",
      "args": [
        "-y",
        "@larksuiteoapi/lark-mcp",
        "mcp",
        "-a",
        "<your_app_id>",
        "-s",
        "<your_app_secret>",
        "-u",
        "<your_user_token>"
      ]
    }
  }
}

Custom API Configuration

Enable specific APIs or presets using the -t parameter:

lark-mcp mcp -a <your_app_id> -s <your_app_secret> -t im.v1.message.create,im.v1.message.list,preset.calendar.default

Available Presets

preset.light - Lightweight common tools with reduced token usage
preset.default - Default comprehensive tool set
preset.im.default - Messaging and chat tools
preset.base.default - Bitable database tools
preset.base.batch - Batch operations for Bitable
preset.doc.default - Document management tools

Examples

Basic Usage with App Authentication

lark-mcp mcp -a cli_xxxx -s yyyyy

Using User Identity

lark-mcp mcp -a cli_xxxx -s yyyyy -u u-zzzz

Using International Lark Domain

lark-mcp mcp -a <your_app_id> -s <your_app_secret> -d https://open.larksuite.com

Enabling Only Specific APIs

lark-mcp mcp -a cli_xxxx -s yyyyy -t im.v1.chat.create,im.v1.message.create

Using SSE Mode

lark-mcp mcp -a cli_xxxx -s yyyyy -m sse --host 0.0.0.0 -p 3000

Using Configuration File

Create a JSON configuration file (config.json):

{
  "appId": "cli_xxxx",
  "appSecret": "xxxx",
  "domain": "https://open.feishu.cn",
  "tools": ["im.v1.message.create","im.v1.chat.create"],
  "toolNameCase": "snake",
  "language": "en",
  "userAccessToken": "",
  "tokenMode": "auto",
  "mode": "stdio",
  "host": "localhost",
  "port": "3000"
}

Then use it:

lark-mcp mcp --config ./config.json

Transport Modes

stdio mode (Default)

lark-mcp mcp -a <your_app_id> -s <your_app_secret> -m stdio

SSE mode

lark-mcp mcp -a <your_app_id> -s <your_app_secret> -m sse -p 3000

Access the SSE endpoint at http://<host>:<port>/sse.

Troubleshooting

Connection issues: Verify network, APP_ID, and APP_SECRET are correct
Token errors: User access tokens expire after 2 hours and need refreshing
Permission errors: Check if your app has the necessary API permissions
Token limit exceeded: Use -t to reduce enabled APIs or use a larger token model

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
