What this is

When your coding agent needs to integrate Morph, it needs to know the API format, tool definitions, and best practices. The llms.txt file contains all of this in a single document (~5k tokens) that fits in any model’s context window. For the full unabridged docs (every page), see llms-full.txt.

​
How to use it

​
Option 1: Add to your project config

Paste the contents of llms.txt into your project’s agent configuration:
  • Claude Code: Add to your project’s CLAUDE.md
  • Cursor: Add to .cursorrules or Settings → Rules for AI
  • Codex: Add to AGENTS.md
  • Custom agent: Include in your system prompt

​
Option 2: Fetch at runtime

const morphDocs = await fetch('https://docs.morphllm.com/llms.txt').then(r => r.text());
// Include in your agent's system prompt or tool context

​
What’s included

The llms.txt file covers every Morph product with working code examples:
  • Fast Apply: The <instruction>/<code>/<update> format, models, TypeScript/Python/cURL examples
