Feishu MCP server

The MCP server provides Feishu (LarkSuite) operations to AI encoding agents such as Cursor, allowing them to read documents, send messages, review contracts, process data, and more. This integration between Feishu and Cursor enables various innovative combinations of functionality.

Creating a Custom Feishu Application

Before running the MCP server, you need to create an application in Feishu and obtain authentication tokens:

1. Create a custom application through the Feishu Open Platform
2. Grant document permissions to your application. This process can be complex, so refer to the permissions documentation and choose the appropriate solution

Setting Up and Running the Server

Installation

1. Copy the example environment file to create your configuration:

   cp .env.example .env
   

2. Modify the .env file with your Feishu application credentials:

   • Set FEISHU_APP_ID to your Feishu custom application's app_id
   • Set FEISHU_APP_SECRET to your Feishu custom application's app_secret

3. Install dependencies and start the server:

   yarn install
   yarn start
   

Integration with Cursor

1. Add the MCP server to Cursor
2. In Agent mode, input Feishu document links to have AI assist with reading and organizing content

Available Tools

get_feishu_doc

This tool retrieves Feishu document information in plain text format. Use it when you need to access content from Feishu documents through your AI agent.

Example usage in Cursor:

• Paste a Feishu document link
• Ask the AI to read, summarize, or analyze the document content

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "feishu" '{"command":"yarn","args":["start"]}'

See the official Claude Code MCP documentation for more details.

For 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 > Tools & Integrations and click "New MCP Server".

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

{
    "mcpServers": {
        "feishu": {
            "command": "yarn",
            "args": [
                "start"
            ]
        }
    }
}

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 explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "feishu": {
            "command": "yarn",
            "args": [
                "start"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
