> **⚠️ Beta Version Notice**: This tool is currently in Beta stage. Features and APIs may change, so please stay updated with version releases.
This is the Feishu/Lark official OpenAPI MCP (Model Context Protocol) tool designed to help users quickly connect to the Feishu/Lark platform and enable efficient collaboration between AI Agents and Feishu/Lark. The tool encapsulates Feishu/Lark Open Platform API interfaces as MCP tools, allowing AI assistants to directly call these interfaces and implement various automation scenarios such as document processing, conversation management, calendar scheduling, and more.
## Preparation
### Creating a Feishu/Lark Application
Before using the lark-mcp tool, you need to create a Feishu/Lark application:
1. Visit the [Feishu Open Platform](https://open.feishu.cn/) or [Lark Open Platform](https://open.larksuite.com/) and log in
2. Click "Console" and create a new application
3. Obtain the App ID and App Secret, which will be used for API authentication
4. Add the necessary permissions for your application based on your usage scenario
5. If you need to call APIs as a user, set the OAuth 2.0 redirect URL to http://localhost:3000/callback
For detailed application creation and configuration guidelines, please refer to the [Feishu Open Platform Documentation - Creating an Application](https://open.feishu.cn/document/home/introduction-to-custom-app-development/self-built-application-development-process#a0a7f6b0).
### Installing Node.js
Before using the lark-mcp tool, you need to install the Node.js environment.
**Using the Official Installer (Recommended)**:
1. Visit the [Node.js website](https://nodejs.org/)
2. Download and install the LTS version
3. After installation, verify in the terminal:
```bash
node -v
npm -v
```
## Quick Start
### Using with Trae/Cursor/Claude
To integrate Feishu/Lark functionality in AI tools like Trae, Cursor or Claude, install using the button below.
[](https://cursor.com/install-mcp?name=lark-mcp&config=eyJjb21tYW5kIjoibnB4IiwiYXJncyI6WyIteSIsIkBsYXJrc3VpdGVvYXBpL2xhcmstbWNwIiwibWNwIiwiLWEiLCJ5b3VyX2FwcF9pZCIsIi1zIiwieW91cl9hcHBfc2VjcmV0Il19)
[](trae-cn://trae.ai-ide/mcp-import?source=lark&type=stdio&config=eyJjb21tYW5kIjoibnB4IiwiYXJncyI6WyIteSIsIkBsYXJrc3VpdGVvYXBpL2xhcmstbWNwIiwibWNwIiwiLWEiLCJ5b3VyX2FwcF9pZCIsIi1zIiwieW91cl9hcHBfc2VjcmV0Il19) [](trae://trae.ai-ide/mcp-import?source=lark&type=stdio&config=eyJjb21tYW5kIjoibnB4IiwiYXJncyI6WyIteSIsIkBsYXJrc3VpdGVvYXBpL2xhcmstbWNwIiwibWNwIiwiLWEiLCJ5b3VyX2FwcF9pZCIsIi1zIiwieW91cl9hcHBfc2VjcmV0Il19)
or add the following to your configuration file:
```json
{
"mcpServers": {
"lark-mcp": {
"command": "npx",
"args": [
"-y",
"@larksuiteoapi/lark-mcp",
"mcp",
"-a",
"<your_app_id>",
"-s",
"<your_app_secret>"
]
}
}
}
```
If you need to access APIs with **user identity**, you need to login first using the login command in the terminal. Note that you need to configure the application's redirect URL in the developer console first, default is http://localhost:3000/callback
```bash
# Login and get user access token
npx -y @larksuiteoapi/lark-mcp login -a cli_xxxx -s yyyyy
# Or optionally, login with specific OAuth scope - if not specified, all permissions will be authorized by default
npx -y @larksuiteoapi/lark-mcp login -a cli_xxxx -s yyyyy --scope offline_access docx:document
```
Then add the following to your configuration file:
```json
{
"mcpServers": {
"lark-mcp": {
"command": "npx",
"args": [
"-y",
"@larksuiteoapi/lark-mcp",
"mcp",
"-a",
"<your_app_id>",
"-s",
"<your_app_secret>",
"--oauth",
"--token-mode", "user_access_token"
]
}
}
}
```
Note: When enabling `--oauth`, it's recommended to explicitly set `--token-mode` to `user_access_token`, which means calling APIs with user access tokens, suitable for accessing user resources or scenarios requiring user authorization (such as reading personal documents, sending IM messages). If you keep the default `auto`, some APIs AI may fallback to `tenant_access_token`, which could result in insufficient permissions or inability to access user private data.
### Domain Configuration
Based on your usage scenario, lark-mcp supports configuring different domain environments:
**Feishu (China Version)**:
- Default uses `https://open.feishu.cn` domain
- Suitable for users in China
**Lark (International Version)**:
- Uses `https://open.larksuite.com` domain
- Suitable for overseas users or international version of Lark
To switch to the international version of Lark, add the `--domain` parameter in your configuration:
```json
{
"mcpServers": {
"lark-mcp": {
"command": "npx",
"args": [
"-y",
"@larksuiteoapi/lark-mcp",
"mcp",
"-a",
"<your_app_id>",
"-s",
"<your_app_secret>",
"--domain",
"https://open.larksuite.com"
]
}
}
}
```
> **💡 Tip**: Ensure your application is created in the corresponding domain environment's open platform. International version applications cannot be used with Feishu China version, and vice versa.
## Custom API Configuration
> ⚠️ **File Upload/Download**: File upload and download operations are not yet supported
> ⚠️ **Document Editing**: Direct editing of Feishu cloud documents is not supported (only importing and reading are available)
By default, the MCP service enables common APIs. To enable other tools or only specific APIs or presets, you can specify them using the `-t` parameter in the MCP Client configuration (JSON):
```json
{
"mcpServers": {
"lark-mcp": {
"command": "npx",
"args": [
"-y",
"@larksuiteoapi/lark-mcp",
"mcp",
"-a", "<your_app_id>",
"-s", "<your_app_secret>",
"-t", "im.v1.message.create,im.v1.message.list,im.v1.chat.create,preset.calendar.default"
]
}
}
}
```
For detailed information about all preset tool collections and which tools are included in each preset, please refer to the [Preset Tool Collections Reference](./docs/reference/tool-presets/presets.md).
A complete list of all supported Feishu/Lark tools can be found in [tools.md](./docs/reference/tool-presets/tools-en.md).
> **⚠️ Notice**：Non-preset APIs have not undergone compatibility testing, and the AI may not perform optimally during the process of understanding and using them.
### Development Integration
Developers can refer to the minimal example for integrating with Agent: [`lark-samples/mcp_quick_demo`](https://github.com/larksuite/lark-samples/tree/main/mcp_quick_demo).
You can also refer to the Lark bot integration example: [`lark-samples/mcp_larkbot_demo/nodejs`](https://github.com/larksuite/lark-samples/tree/main/mcp_larkbot_demo/nodejs).
This example demonstrates how to integrate MCP capabilities into Feishu/Lark bots, triggering tool calls and message sending through bot conversations, suitable for scenarios that integrate existing tools into Bot.
### Advanced Configuration
For detailed configuration options and deployment scenarios, please refer to our [Configuration Guide](./docs/usage/configuration/configuration.md).
For detailed information about all available command line parameters and their usage, please refer to the [Command Line Reference](./docs/reference/cli/cli.md).
