@lexq/cli

LexQ CLI

Manage policies, simulate rules, and deploy from the terminal. Built for humans and AI agents.

Install

npm install -g @lexq/cli

Or run without installing:

npx @lexq/cli

Requires Node.js 18+.

Quick Start

# 1. Authenticate
lexq auth login
# Enter your API key (create one at console.lexq.io → Management → API Keys)

# 2. Verify
lexq auth whoami

# 3. Create a policy group
lexq groups create --json '{"name":"my-policy","priority":0}'

# 4. Create a draft version
lexq versions create --group-id <GROUP_ID> --json '{"commitMessage":"v1"}'

# 5. Add a rule
lexq rules create --group-id <GROUP_ID> --version-id <VERSION_ID> --json '{
  "name": "VIP Discount",
  "priority": 0,
  "condition": {
    "type": "SINGLE",
    "field": "customer_tier",
    "operator": "EQUALS",
    "value": "VIP",
    "valueType": "STRING"
  },
  "actions": [{
    "type": "DISCOUNT",
    "parameters": {"method":"PERCENTAGE","rate":10,"refVar":"payment_amount"}
  }]
}'

# 6. Test
lexq analytics dry-run --version-id <VERSION_ID> --debug --mock \
  --json '{"facts":{"customer_tier":"VIP","payment_amount":100000}}'

# 7. Deploy
lexq deploy publish --group-id <GROUP_ID> --version-id <VERSION_ID> --memo "v1"
lexq deploy live --group-id <GROUP_ID> --version-id <VERSION_ID> --memo "Initial deploy"

AI Agent Skills

LexQ CLI ships with AI Agent Skills — structured documentation that AI coding agents can read to autonomously manage policies.

For AI Agent Developers

Skills are included in the npm package. After installing @lexq/cli, agents can read skills from:

node_modules/@lexq/cli/skills/
node_modules/@lexq/cli/AGENTS.md
node_modules/@lexq/cli/CONTEXT.md

Or reference them directly in your project by copying the skills/ directory.

Configuration

Config is stored at ~/.lexq/config.json:

{
  "apiKey": "sk_live_xxxxxxxxxxxxx",
  "baseUrl": "https://api.lexq.io/api/v1/partners",
  "format": "json"
}

Development

git clone https://github.com/sanghyunp-dev/lexq-cli.git
cd lexq-cli
pnpm install
pnpm build
pnpm start -- groups list

pnpm typecheck     # Type check
pnpm lint          # ESLint
bash tests/e2e.sh  # E2E tests (requires API key)

MCP Server Mode

Run LexQ CLI as an MCP (Model Context Protocol) server for seamless AI agent integration:

lexq serve --mcp

This starts a stdio MCP server exposing 53 tools — the full LexQ API — to any MCP-compatible client.

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers":{
    "lexq":{
      "command":"npx",
      "args":[
        "-y",
        "@lexq/cli",
        "serve",
        "--mcp"
      ]
    }
  }
}

Claude.ai (Web)

Settings → MCP Servers → Add:

• Command: npx
• Args: -y @lexq/cli serve --mcp

VS Code / Cursor

.vscode/mcp.json:

{
  "servers":{
    "lexq":{
      "command":"npx",
      "args":[
        "-y",
        "@lexq/cli",
        "serve",
