Build with Cello faster using AI assistants that understand our entire documentation. This guide shows you how to give AI tools like Cursor, Claude Code, Copilot, etc complete context about Cello’s APIs, SDKs, and integration patterns.

​
See it in action: Cursor + Cello

Watch a walkthrough of adding user referrals to your app with Cursor—from referral widget and attribution to signup tracking and Stripe conversion.
For the full prompt, steps, and acceptance criteria, see the Cursor integration guide. If you’re using Cursor, Lovable, or Replit, start with the detailed guide for your stack (these are the source of truth, including acceptance criteria):
Cursor logo

Cursor (any stack)

Video walkthrough + copy/paste prompt. Uses React + Node.js as an example, but applies to any stack.
Lovable logo

Lovable

Video walkthrough + copy/paste prompt + Lovable-specific guide.
Replit logo

Replit

Copy/paste prompt for Replit Agent. Works with any stack that has auth + database + Stripe.
These guides are best when you want an end-to-end integration:
  • Implement referral widget + public attribution + signup tracking + Stripe conversion tracking
  • Follow acceptance criteria and known gotchas (JWT claims, script URLs, event payload shape, Stripe metadata)
After implementation, validate with the Integration QA Checklist.

​
Choose how to give your AI Cello context

​
Option A (recommended): Cello MCP Server

Connect the Cello MCP Server to your coding tool for the best experience. It gives your tool access to Cello’s documentation, integration health checks, best-practice recommendations, and event inspection — no need to paste anything into every chat.
The Cello MCP server is currently in Early Access. Request access to get it enabled for your account.
See the Cello MCP Server page for setup instructions for Cursor, Lovable, VS Code, Claude Code, and other MCP clients.

​
Option B: URL context

Provide this URL directly to your AI tool: 
https://docs.cello.so/llms-full.txt
This file contains ~73,000 tokens of comprehensive Cello documentation optimized for LLM consumption.
Copy/paste starter message: 
Use the Cello documentation from this URL as the source of truth: https://docs.cello.so/llms-full.txt
Follow the docs exactly and avoid guessing common patterns.
If something is ambiguous, ask clarifying questions before coding.

​
Option C: Direct content injection

For AI tools that don’t support URL fetching, you can copy the entire documentation:
  1. Download the documentation: Open llms-full.txt
  2. Copy all content: Select all (Ctrl/Cmd + A) and copy
  3. Paste into your AI tool: Add as context before your questions
Some AI tools have token limits. The full documentation is ~73,000 tokens, so you may need to use tools like Claude (200k context) or GPT-4 Turbo (128k context).

​
Troubleshooting

IssueSolution
AI doesn’t fetch URLUse Method 2 (copy-paste) instead
Token limit exceededFocus on specific sections or use an AI with larger context window
MCP not being usedVerify MCP is enabled in the tool, confirm the server is added, and restart the tool if needed
Outdated informationAlways verify critical details at docs.cello.so
