- Node.js (
npm/npx) - Go
v1.23+ and Python 3 (only required for building from source)
Quick Start (Human Users)
Note for AI assistants: If you are an AI Agent helping the user with installation, jump directly to Quick Start (AI Agent), which contains all the steps you need to complete.
Install
Choose one of the following methods:
Option 1 — From npm (recommended):
npx @larksuite/cli@latest installOption 2 — From source:
Requires Go v1.23+ and Python 3.
git clone https://github.com/larksuite/cli.git

The following steps are for AI Agents. Some steps require the user to complete actions in a browser.
Step 1 — Install
npx @larksuite/cli@latest installStep 2 — Configure app credentials
Run this command in the background. It will output an authorization URL — extract it and send it to the user. The command exits automatically after the user completes the setup in the browser.

lark-cli im +messages-send --as bot --chat-id "oc_xxx" --text "Hello"Three-Layer Command System
The CLI provides three levels of granularity, covering everything from quick operations to fully custom API calls:
1. Shortcuts
Prefixed with +, designed to be friendly for both humans and AI, with smart defaults, table output, and dry-run previews.
lark-cli calendar +agenda
lark-cli im +messages-send --chat-id "oc_xxx" --text "Hello"
lark-cli docs +create --doc-format markdown --content $'<title>Weekly Report</title>\n# Progress\n- Completed feature X'Run lark-cli <service> --help to see all shortcut commands.
2. API Commands
Auto-generated from Lark OAPI metadata, curated through evaluation and quality gates — 100+ commands mapped 1:1 to platform endpoints.
lark-cli calendar calendars list
lark-cli calendar events instance_view --params '{"calendar_id":"primary","start_time":"1700000000","end_time":"1700086400"}'3. Raw API Calls
Call any Lark Open Platform endpoint directly, covering 2500+ APIs.
lark-cli api GET /open-apis/calendar/v4/calendars
lark-cli api POST /open-apis/im/v1/messages --params '{"receive_id_type":"chat_id"}' --data '{"receive_id":"oc_xxx","msg_type":"text","content":"{\"text\":\"Hello\"}"}'Advanced Usage
Output Formats
--format json # Full JSON response (default)
--format pretty # Human-friendly formatted output
--format table # Readable table
--format ndjson # Newline-delimited JSON (for piping)
--format csv # Comma-separated valuesJSON Output Contract
With --format json (the default), success and error envelopes are distinct.
Success goes to stdout, exit code 0:
{ "ok": true, "identity": "user", "data": { "guid": "..." }, "meta": { "count": 1 } }Errors go to stderr, non-zero exit code:
{ "ok": false, "identity": "user", "error": { "type": "api", "subtype": "...", "code": 99991679, "message": "...", "hint": "..." } }To check whether a command succeeded, test ok == true (or the exit code) — not code == 0. Unlike raw OpenAPI responses ({"code": 0, "msg": "ok", ...}), the success envelope carries no code or msg field; code appears only inside error as the upstream OpenAPI code. See errs/ERROR_CONTRACT.md for the full error taxonomy.
Pagination
--page-all # Auto-paginate through all pages
--page-limit 5 # Max 5 pages
--page-delay 500 # 500ms between page requestsDry Run
For commands that may have side effects, preview the request with --dry-run first:
lark-cli im +messages-send --chat-id oc_xxx --text "hello" --dry-runSchema Introspection
Use schema to inspect any API method's parameters, request body, response structure, supported identities, and scopes:
lark-cli schema
lark-cli schema calendar.events.instance_view
lark-cli schema im.messages.deleteSecurity & Risk Warnings (Read Before Use)
This tool can be invoked by AI Agents to automate operations on the Lark/Feishu Open Platform, and carries inherent risks such as model hallucinations, unpredictable execution, and prompt injection. After you authorize Lark/Feishu permissions, the AI Agent will act under your user identity within the authorized scope, which may lead to high-risk consequences such as leakage of sensitive data or unauthorized operations. Please use with caution.
To reduce these risks, the tool enables default security protections at multiple layers. However, these risks still exist. We strongly recommend that you do not proactively modify any default security settings; once relevant restrictions are relaxed, the risks will increase significantly, and you will bear the consequences.
We recommend using the Lark/Feishu bot integrated with this tool as a private conversational assistant. Do not add it to group chats or allow other users to interact with it, to avoid abuse of permissions or data leakage.
To reduce the security risks associated with access token theft, the CLI sends a minimal set of risk-control signals with OpenAPI requests made to exact official Feishu/Lark HTTPS domains. These signals are used to help identify anomalous API activity. This protection is enabled by default. The information sent is limited to:
- Operating system type: macOS, Windows, or Linux
- Device hardware model: for example, Mac17,9
To disable this protection for the current workspace, run:
lark-cli config risk-control offTo enable this protection for the current workspace, run:
lark-cli config risk-control onTo restore the default policy for the current workspace, run:
lark-cli config risk-control defaultPlease fully understand all usage risks. By using this tool, you are deemed to voluntarily assume all related responsibilities.
