Outlit Sdk MCP Server

Outlit SDK

TypeScript SDK for the Outlit events ingestion API. Track user interactions, page views, and custom events across web and server applications.

Packages

This monorepo contains these packages under the @outlit scope:

• @outlit/core - Core SDK functionality and base client
• @outlit/browser - Browser-specific SDK with automatic page view tracking
• @outlit/node - Node.js SDK for server-side event tracking
• @outlit/cli - CLI for Outlit customer intelligence
• @outlit/tools - Customer intelligence tool contracts and client helpers
• @outlit/pi - Pi package for Outlit customer intelligence tools

Installation

Choose the package that matches your environment:

# For browser applications
npm install @outlit/browser

# For Node.js applications
npm install @outlit/node

# For custom implementations
npm install @outlit/core

Quick Start

Browser

import { Outlit } from '@outlit/browser'

const outlit = new Outlit({
  publicKey: 'pk_xxx',
  trackPageviews: true,
  trackForms: true,
})

// Identify a user
outlit.user.identify({
  email: 'user@example.com',
  traits: { name: 'John Doe' },
  customerId: 'cust_123', // Your app's account/workspace/customer ID
  customerTraits: { plan: 'pro' },
})

// Track events
outlit.track('button_clicked', {
  button_id: 'signup',
  page: '/homepage',
})

// Mark billing status on a customer
outlit.customer.trialing({
  customerId: 'cust_123', // Your app's account/workspace/customer ID
  properties: { plan: 'pro' },
})

Using the singleton API

import { init, track, user, customer } from '@outlit/browser'

// Initialize once at app startup
init({ publicKey: 'pk_xxx' })

// Then use anywhere
track('page_viewed', { page: '/home' })
user().identify({
  email: 'user@example.com',
  customerId: 'cust_123', // Your app's account/workspace/customer ID
})
customer().paid({
  customerId: 'cust_123', // Your app's account/workspace/customer ID
  properties: { plan: 'pro' },
})

Using with React

import { OutlitProvider, useOutlit } from '@outlit/browser/react'

// Wrap your app
function App() {
  return (
    <OutlitProvider publicKey="pk_xxx">
      <MyComponent />
    </OutlitProvider>
  )
}

// Use in components
function MyComponent() {
  const { track, user } = useOutlit()
  
  return (
    <button onClick={() => user.activate({ milestone: 'onboarding' })}>
      Click me
    </button>
  )
}

Node.js

import { Outlit } from '@outlit/node'

const outlit = new Outlit({
  publicKey: 'pk_xxx',
})

// Track server-side events (requires identity)
outlit.track({
  customerId: 'cust_123', // Your app's account/workspace/customer ID
  eventName: 'api_request',
  properties: {
    endpoint: '/api/users',
    method: 'GET',
    status: 200,
  },
})
// `customerId`-only track events are valid immediately.
// When you later call identify() with the same customerId and an email,
// Outlit can link that account/workspace to the customer resolved from email.

// Identify a user
outlit.user.identify({
  email: 'user@example.com',
  traits: { plan: 'pro' },
  customerId: 'cust_123', // Your app's account/workspace/customer ID
  customerTraits: { plan: 'pro' },
})

// Mark customer billing status
outlit.customer.paid({
  customerId: 'cust_123', // Your app's account/workspace/customer ID
  properties: { plan: 'pro' },
})

// Flush events before shutdown
await outlit.flush()

Features

• Modern TypeScript - Full TypeScript support with type definitions
• Tree-shakeable - Optimized bundle size with dual ESM/CJS exports
• Event Queueing - Automatic batching and flushing of events
• Multi-platform - Separate packages for browser and Node.js
• Auto-tracking - Automatic page view tracking in browser
• Middleware Support - Easy integration with Express and similar frameworks
• Persistent Identity - User and anonymous ID persistence
• High Performance - Minimal overhead and efficient batching
• Type Safe - Full TypeScript support with strict types

Examples

• Pi agents - Build customer intelligence agents in Pi with @outlit/pi

Development

This project uses a modern monorepo setup with the following tools:

• Bun - Fast all-in-one JavaScript runtime and package manager
• Turbo - Build system for monorepo orchestration
• TypeScript - Type-safe JavaScript
• tsup - Fast TypeScript bundler
• Biome - Fast linter and formatter
• Playwright - End-to-end testing
• Changesets - Version management and changelogs

Setup

# Install dependencies
bun install

# Build all packages
bun run build

# Run tests
bun run test

# Lint code
bun run lint

# Type check
bun run typecheck

# Format code
bun run format

Creating a Changeset

When making changes that should be released, create a changeset:

bunx changeset

This will prompt you to:

1. Select which packages are affected
2. Choose the version bump type (patch, minor, major)
3. Write a description of the change

The changeset file will be committed with your PR and used to generate changelogs on release.

CI/CD

Workflows

• CI (ci.yml) - Runs on PRs: lint, typecheck, build, test
• Release (release.yml) - Runs on main: publish canary to npm + CDN, create version PR or publish stable releases

Required Secrets

For maintainers setting up the repository:

Creating NPM_TOKEN

1. Go to npmjs.com and sign in
2. Navigate to Access Tokens → Generate New Token → Granular Access Token
3. Set permissions: Read and write for @outlit packages
4. Copy the token and add as NPM_TOKEN secret in GitHub

Creating GCP_CREDENTIALS

1. Go to Google Cloud Console
2. Navigate to IAM & Admin → Service Accounts
3. Create a new service account (e.g., github-actions-deployer)
4. Grant "Storage Object Admin" role on the cdn.outlit.ai bucket
5. Create a JSON key for the service account
6. Copy the entire JSON content and add as GCP_CREDENTIALS secret in GitHub

CDN Deployment

The browser SDK IIFE bundle is deployed to Google Cloud Storage:

npm tags:

Manual deployment (requires gcloud CLI):

cd packages/browser && bun run deploy:canary   # Deploy to canary
cd packages/browser && bun run deploy:stable   # Deploy to stable (requires confirmation)
cd packages/browser && bun run deploy:version  # Deploy versioned release
