Lark

Cursor plugin that connects agents to Lark (Lark Suite, the international product) through Lark's official remote Model Context Protocol server.

Search, create, fetch, and update Lark Docs, work with doc comments and files, and read Lark IM groups and messages in the signed-in Lark account.

Install

1. Open Cursor Settings → Plugins.
2. Search for Lark.
3. Click Install, then complete the Lark sign-in prompt.

Or run /add-plugin lark in chat.

Accounts on China-region Feishu should install the separate Feishu plugin instead. This plugin talks only to mcp.larksuite.com.

Lark Base (Bitable) is the separate Lark Base plugin.

Auth is MCP OAuth (Bearer). Cursor discovers the authorization server when the plugin connects and prompts for Lark login. Lark supports Dynamic Client Registration, so there is no API token, client ID, client secret, or custom header to configure.

Before you connect

You need a Lark Suite account. Unauthenticated requests to the server are rejected until that login completes.

What agents can do

Category	Capabilities
Docs	Search, create, fetch, and update docs; doc comments; list docs
IM	Search groups, list group members, get and search messages, read a thread, and check read status
People and files	Look up the signed-in user, search users, and fetch files

Advertised tools include fetch-file-v2, get-user, search-user, list-docs-v2, search-groups, get-group-members, get-thread-messages, and get-read-status, plus doc search/create/fetch/update, doc comments, and message get/search. The offline_access scope is advertised so the connection can refresh. The hosted runtime is the source of truth for tool names and schemas.

Notes

• Tool calls run as the Lark user who authorizes the connection and cannot exceed that user's permissions.
• This plugin points only at Lark's official hosted endpoint. It does not wrap the local @larksuiteoapi/lark-mcp stdio server, and it does not take an app id, app secret, user access token, or X-Lark-MCP-* header.
• Lark hosts the server itself. OAuth metadata is discovered at connect time (protected resource https://mcp.larksuite.com/.well-known/oauth-protected-resource/mcp, authorization server https://accounts.larksuite.com/mcp, dynamic client registration https://open.larksuite.com/open-apis/app/v1/dcr).
• China-region Feishu is a separate plugin (feishu) pointing at https://mcp.feishu.cn/mcp.
• Revoke access at any time from your Lark account.
