Feishu User Plugin

Please install the `feishu-user-plugin` MCP server into my current AI client (that's you).

Required prerequisites (do these first if not already done):
- **Install Node.js 18 or newer** — Node.js >= 18 is required to run the npm package via npx. (https://nodejs.org/)

Optional prerequisites:
- Set up Feishu/Lark credentials — This server supports three independent auth layers. Configure whichever credentials are needed for the tools you plan to use: LARK_COOKIE for user-identity message sending; LARK_APP_ID and LARK_APP_SECRET for official API features such as docs, sheets, wiki, drive, calendar, tasks, OKR, contacts, and realtime events; LARK_USER_ACCESS_TOKEN and LARK_USER_REFRESH_TOKEN for user OAuth features like reading P2P chats and user-owned writes. The README setup flow shows: npx feishu-user-plugin setup --app-id <APP_ID> --app-secret <APP_SECRET> and npx feishu-user-plugin oauth. Run: `npx feishu-user-plugin setup --app-id <your-app-id> --app-secret <your-app-secret>
npx feishu-user-plugin oauth` (docs/AUTH-SETUP.md)

Canonical MCP server config (stdio transport):
- command: `npx`
- args: ["feishu-user-plugin"]
- optional environment variables:
  - `LARK_COOKIE`: Feishu cookie used for the cookie + protobuf user-identity path. Enables sending messages as the user for supported tools. (example: `<your-lark-cookie>`)
  - `LARK_APP_ID`: Feishu/Lark self-built app ID for official API access. Required together with LARK_APP_SECRET for bot/API features such as docs, bitable, wiki, drive, calendar, tasks, OKR, contacts, and realtime events. (example: `<your-app-id>`)
  - `LARK_APP_SECRET`: Feishu/Lark self-built app secret for official API access. Required together with LARK_APP_ID for bot/API features. (example: `<your-app-secret>`)
  - `LARK_USER_ACCESS_TOKEN`: User OAuth access token (UAT). Used for P2P chat reading, user chat lists, and user-owned writes for some resources. (example: `<your-user-access-token>`)
  - `LARK_USER_REFRESH_TOKEN`: User OAuth refresh token paired with LARK_USER_ACCESS_TOKEN. (example: `<your-user-refresh-token>`)

Note: The README emphasizes that the three auth layers are independent: configure any one layer and the corresponding tools become available. The simplest portable MCP launch path is via npx. The package also provides setup helpers that write client-specific config, but the canonical MCP server shape is command: npx, args: ["feishu-user-plugin"].

Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.
