飞书 MCP Server

让 Claude Code 以你的身份直接操作飞书——创建文档、写入内容、发送消息、调用任意飞书 API。

原理

你说"帮我写飞书文档" → Claude → MCP Server → 飞书 API(你的身份)
                                              ↑
                               OAuth 2.0 User Access Token

不是用"机器人"身份,而是通过 OAuth 授权拿到你的用户 Token,飞书看到的所有操作都是你本人做的。

准备工作

1. 创建飞书应用

  1. 打开 飞书开放平台,进入开发者后台
  2. 创建 企业自建应用
  3. 凭证与基础信息 中记录 App IDApp Secret

2. 配置权限

进入应用的 权限管理,添加以下权限:

  • docx:document — 文档读写
  • docx:document:readonly — 文档读取
  • drive:drive — 云空间操作

3. 配置 OAuth 重定向 URL

进入 安全设置 → 重定向 URL,添加:

http://localhost:3040/callback

4. 发布应用

应用发布 中创建版本并发布(管理员审批后生效)。


安装

# 1. 克隆项目
git clone <repo-url>
cd feishu-mcp-server

# 2. 安装依赖
npm install

# 3. 配置凭证
cp .env.example .env
# 编辑 .env,填入 App ID 和 App Secret

授权

node auth.js

浏览器会自动打开飞书授权页 → 点「确认授权」→ refresh_token 自动写入 .env

配置 Claude Code

编辑 用户级 settings.json(~/.claude/settings.jsonC:\Users\<用户名>\.claude\settings.json):

{
  "mcpServers": {
    "feishu": {
      "command": "node",
      "args": ["<项目路径>/index.js"]
    }
  }
}

用户级配置让所有项目共用,不需要每个项目重复配。

重启 Claude Code 后生效。


使用

通过 Claude Code(对话)

"帮我在飞书创建一个名为「周会纪要」的文档"
"把下面这段分析写到飞书文档 xxx 末尾"
"读取飞书文档 xxx 的内容,帮我总结一下"

通过命令行(独立使用)

# 创建一个能被 Claude 读写的文档
node create-doc.js "文档标题"

可用工具

工具 说明
feishu_create_document 创建新文档
feishu_write_document_content 写入内容(支持 Markdown)
feishu_get_document 读取文档
feishu_send_message 发送消息
feishu_call_api 调用任意飞书 API

# Feishu MCP Server (English)

Let Claude Code operate Feishu/Lark **as you** — create documents, write content, send messages, call any Feishu API.

## How It Works

You: "Create a doc in Feishu" → Claude → MCP Server → Feishu API (your identity) ↑ OAuth 2.0 User Access Token


Instead of a bot identity, the server uses OAuth to obtain a **user access token**. Every action appears in Feishu as done by **you personally** — so you can see and edit everything.

## Prerequisites

### 1. Create a Feishu App

1. Go to [Feishu Open Platform](https://open.feishu.cn) → Developer Console
2. Create an **Enterprise Internal App**
3. Note the `App ID` and `App Secret` from **Credentials & Basic Info**

### 2. Configure Permissions

Navigate to **Permission Management** and add:

- `docx:document` — Read & write documents
- `docx:document:readonly` — Read documents
- `drive:drive` — Cloud drive operations

### 3. Configure OAuth Redirect URL

Go to **Security Settings** → Redirect URL, add:

http://localhost:3040/callback


### 4. Publish the App

Create a version under **App Publish** and submit for admin approval.

---

## Installation

```bash
git clone <repo-url>
cd feishu-mcp-server
npm install
cp .env.example .env
# Edit .env with your App ID and App Secret

Authorization

node auth.js

A browser window opens → authorize the app → refresh_token is saved to .env automatically.


Configure Claude Code

Edit your user-level settings.json (~/.claude/settings.json on macOS/Linux, or C:\Users\<username>\.claude\settings.json on Windows):

{
  "mcpServers": {
    "feishu": {
      "command": "node",
      "args": ["<path-to-project>/index.js"]
    }
  }
}

User-level config means it works across all projects. Restart Claude Code to load.


Usage

Via Claude Code

"Create a new doc in Feishu called 'Meeting Notes'"
"Append this analysis to Feishu doc xxx"
"Read Feishu doc xxx and summarize it"

Command Line

# Create a doc that Claude can read & write
node create-doc.js "Document Title"

Tools

Tool Description
feishu_create_document Create a new document
feishu_write_document_content Write content (supports Markdown)
feishu_get_document Read a document
feishu_send_message Send a message to a user or chat
feishu_call_api Call any Feishu API directly
