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 (any stack)

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

Lovable

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

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): 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 B: 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).

​
Option C: MCP server integration

For advanced integrations, connect directly to our Model Context Protocol (MCP) server: 
https://docs.cello.so/mcp
Use MCP when you want repeatable, structured access to Cello docs without pasting large context into every chat.
Add the Cello MCP server in your AI tool: Claude Code 
claude mcp add --transport http Cello https://docs.cello.so/mcp
Cursor One-click install (opens Cursor and adds the MCP server): Add Cello MCP to Cursor
The link works when Cursor is installed; click it from a browser or app that supports the cursor:// protocol. If it doesn’t open Cursor, use the manual config below.
Manual config: Edit ~/.cursor/config/mcp.json (macOS/Linux) or %USERPROFILE%\.cursor\config\mcp.json (Windows). Add Cello to mcpServers: 
{
  "mcpServers": {
    "Cello": {
      "url": "https://docs.cello.so/mcp"
    }
  }
}
Or use Cursor Settings → Tools & Integrations → MCP Servers → Add Server, then add the URL above. VS Code (with Copilot) Create or edit .vscode/mcp.json in your workspace (or use MCP: Add Server from the Command Palette and choose Workspace or Global). Add: 
{
  "servers": {
    "Cello": {
      "type": "http",
      "url": "https://docs.cello.so/mcp"
    }
  }
}
This provides structured access to Cello documentation for MCP-compatible AI applications.

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
