@yoreland/lark-cli-mcp

One-line npx MCP server that lets AI clients (Amazon Quick Desktop, Claude Desktop, …) operate Feishu / Lark as your own user identity — send, read, reply, and search messages.

It wraps the official lark-cli (bundled as a dependency, no separate install) and exposes 19 tools over MCP stdio — messaging, cloud docs, Wiki, Drive, and Bitable. Because every call runs with --as user, the sender/creator shown in Feishu is you, not a bot.

Quick start (for workshop attendees)

1) One-time login (in a terminal)

# Bind the shared Feishu app (scan the QR code)
npx -y @yoreland/lark-cli-mcp -- config init --new

# OAuth device-flow login as yourself
npx -y @yoreland/lark-cli-mcp auth

# Sanity check (should report logged-in)
npx -y @yoreland/lark-cli-mcp doctor

2) Add the MCP server in Amazon Quick Desktop

Go to Settings → Capabilities → MCP → + Add MCP:

In the dialog, use Paste JSON config and paste:

{
  "command": "npx",
  "args": ["-y", "@yoreland/lark-cli-mcp"]
}

Click Apply → Save. The server should show 19 tools · Connected ✅

Manual form instead of JSON? Connection type = Local, Command = npx, Arguments = -y @yoreland/lark-cli-mcp. Arguments are space-split (no spaces inside the package name, so this is safe).

3) (Recommended) Add the skill

Settings → Capabilities → Skills → Upload, then select skill/feishu-lark/SKILL.md. Toggle it Active.

The skill teaches Quick when and how to use the 19 tools (resolve chat_id/open_id first, confirm before sending, Bitable field handling, etc.) — the MCP provides the tools, the skill makes Quick use them well.

4) Try it

• "看看 XX 群最近聊了什么"

• "帮我找一下某人"

• "搜一下我的飞书文档里有没有 …"

• "列一下这个多维表格 <URL> 的记录"

Prerequisites

• Node.js v18+ (node -v)

• An MCP client (Amazon Quick Desktop / Claude Desktop / etc.)

• A Feishu/Lark account in the org running the workshop

• Network access to npm registry and Feishu OAuth

The Feishu App ID / Secret is provided centrally by the workshop host and baked into the shared lark-cli config — attendees only do the OAuth login step. (See Host setup.)

Behind the Great Firewall? Use a mirror: npm config set registry https://registry.npmmirror.com

Commands

npx -y @yoreland/lark-cli-mcp            # start MCP server (stdio) — what the client runs
npx -y @yoreland/lark-cli-mcp auth       # OAuth device-flow login (user identity)
npx -y @yoreland/lark-cli-mcp status     # show auth status
npx -y @yoreland/lark-cli-mcp logout     # clear token
npx -y @yoreland/lark-cli-mcp doctor     # environment + login self-check
npx -y @yoreland/lark-cli-mcp -- <args>  # passthrough to bundled lark-cli

The tools

Messaging (IM)

Docs / Wiki / Drive

Bitable (multi-dimensional tables)

Talk to it naturally

Host setup

The workshop host creates one Feishu custom app and configures it so attendees share the same App ID/Secret but each authorize their own account.

1. Feishu Open Platform → create an internal custom app → note App ID / App Secret.

2. Enable User token scopes matching the im, contact, search domains (message read/write, reply, chat read, user search, message search).

3. Distribute the App ID/Secret to attendees via lark-cli config (or a pre-bound config). The login step requests scopes via --domain im,contact,docs,wiki,drive,base.

auth uses OAuth Device Flow, so no redirect URL / localhost:3000 callback configuration is required.

Troubleshooting

missing required scope(s) — re-login with the needed domain:

npx -y @yoreland/lark-cli-mcp auth --domain im,contact,docs,wiki,drive,base

Client shows "No tools loaded" — run npx -y @yoreland/lark-cli-mcp doctor; confirm Node ≥18 and that auth status is OK.

Token expired — just re-run auth.

Known limitations

• No image/file attachment sending (text + markdown only)

• No interactive cards

• No group creation

• Tokens expire; re-run auth when they do
