LLM resources for AI

Updated: Jun 10, 2026

Meta provides LLM-optimized documentation for all Meta Horizon OS development platforms. These resources are designed to be consumed by AI assistants and large language models, enabling accurate and up-to-date responses when you use AI tools for Meta Quest development.

LLM-optimized documentation

Meta publishes developer documentation in a machine-readable format optimized for LLM consumption, providing clean text without navigation chrome, ads, or other page elements that reduce accuracy.

Platform documentation indices

Each build path has its own documentation index listing all available pages:

Unity documentation index

Unreal documentation index

Spatial SDK documentation index

Android Apps documentation index

Native documentation index

Web documentation index

Accessing LLM resources

Through the MCP server

Meta VR CLI provides tools that retrieve documentation automatically:

search_doc — Searches across Meta Horizon OS documentation for relevant pages.

fetch_meta_quest_doc — Fetches the full content of a specific documentation page by URL.

When you ask your AI assistant a question about Meta Quest development, it uses these tools to find and retrieve the relevant documentation pages.

Direct access

You can also point any LLM or AI tool at the documentation URLs directly. The base URL pattern is:

https://developers.meta.com/horizon/llmstxt/documentation/{platform}/{page-slug}.md/

Replace {platform} with your build path (unity, unreal, spatial-sdk, android-apps, native, or web) and {page-slug} with the page identifier. Start with the documentation index for your platform to discover available pages.
