AI Chat

The docs layout includes an Ask AI button (cmd/ctrl + I) which allows you to ask questions about the documentation.

LLMs.txt

Better Auth publishes an LLMs-friendly index of the documentation. Point your assistant at it, or paste the URL into tools that ingest project context.

• Index: https://www.better-auth.com/llms.txt

The index links to per-page Markdown under /llms.txt/docs/... so tools can fetch only the sections they need.

MCP Server

Better Auth hosts a remote MCP server that exposes documentation search, examples, and setup help to any MCP-capable client (Cursor, Claude Code, Open Code, and others).

Endpoint: https://mcp.better-auth.com/mcp

Using the CLI

Run the Better Auth CLI and pick your client:

npx auth@latest mcp

With no flags, the command lists supported targets. You can pass a target directly:

CursorClaude CodeOpen CodeManual

npx auth@latest mcp --cursor

This opens Cursor with a deeplink so the server is added to your MCP configuration.

You can also use the one-click control on this site:

npx auth@latest mcp --claude-code

This runs claude mcp add with the Better Auth URL. If that fails, the CLI prints the exact command to run yourself.

npx auth@latest mcp --open-code

This merges a better-auth entry into opencode.json in the current directory (remote transport, URL above).

npx auth@latest mcp --manual

Writes or merges mcp.json in the current working directory with:

{
  "better-auth": {
    "url": "https://mcp.better-auth.com/mcp"
  }
}

For Cursor, you can add the same better-auth entry to MCP config—commonly ~/.cursor/mcp.json (user) or .cursor/mcp.json (project)—using the shape your Cursor version expects for HTTP servers (url for remote MCP).

Restart or reload MCP in your client after changes.

Skills

Agent skills are portable instruction files (for example SKILL.md) that teach your coding agent project conventions, safe patterns, and where to look in the docs. The Better Auth skill pack lives in the better-auth/skills repository.

Install it with the skills CLI (uses npx so nothing global is required):

npx skills add better-auth/skills

Your editor or agent loads skills from its configured skills directory (often project-level). After installing, restart the agent or reload skills if your tool requires it.
