# LLMs

Mercur documentation is optimized for Large Language Models using the [llms.txt standard](https://llmstxt.org). This gives AI tools a structured map of all documentation — so they can answer technical questions accurately instead of guessing.

Think of it like a sitemap, but for AI: a machine-readable file that describes what documentation exists, how it's organized, and where to find specific topics.

<Note>
  This page is for **chat assistants and hosted tools** (Claude, ChatGPT). If you're using a coding agent *inside* a Mercur project, prefer the version-matched docs bundled in `node_modules/@mercurjs/docs/` — see [Building with AI](/rc/resources/ai/overview).

## Available files

### llms.txt

A structured index of all Mercur documentation pages with descriptions and links.

```
https://docs.mercurjs.com/llms.txt
```

Use this when your AI tool supports llms.txt natively or when you want to give it an overview of what's available without sending the full content.

### llms-full.txt

The entire Mercur documentation compiled into a single plain-text file.

```
https://docs.mercurjs.com/llms-full.txt
```

Use this when you want to give an LLM the complete context in one shot — ideal for complex questions that span multiple topics.

## How to use

<Tabs>
  <Tab title="Claude Projects">
    1. Open [Claude](https://claude.ai) and create a new Project
    2. In project knowledge, add a URL: `https://docs.mercurjs.com/llms-full.txt`
    3. Claude now has full Mercur documentation context in every conversation within that project
  </Tab>

  <Tab title="ChatGPT">
    1. Download `https://docs.mercurjs.com/llms-full.txt`
    2. Upload it as a file in your conversation or attach it to a Custom GPT's knowledge base
  </Tab>

  <Tab title="AI IDE (paste)">
    For any AI coding tool that accepts context:

    1. Fetch the file: `curl -o mercur-docs.txt https://docs.mercurjs.com/llms-full.txt`
    2. Attach it to your conversation or project context
  </Tab>

## When to use llms.txt vs MCP

| Approach                               | Best for                                                           |
| -------------------------------------- | ------------------------------------------------------------------ |
| **llms.txt / llms-full.txt**           | One-time context loading, tools without MCP support, offline use   |
| **[MCP Server](/rc/resources/ai/mcp)** | Live search, always up-to-date results, integrated AI environments |

For the best experience, use the [MCP server](/rc/resources/ai/mcp) if your tool supports it. Fall back to llms.txt when MCP isn't available.
