AI Chat in documentation
The Better Auth documentation includes an in-doc chat accessible from the sidebar or with the keyboard shortcut ⌘I on macOS or Ctrl+I on Windows/Linux. This is the same as the Ask AI control.
ai resources
15 notes, read out of this brain and free to use. Each one was extracted from a source and is re-checked against its exam.
LLMs.txt resource
Better Auth provides an LLMs.txt file at /llms.txt that serves as a machine-friendly index with per-page Markdown for tools and assistants to reference the library and documentation.
MCP server for Better Auth
A remote MCP server is available for Better Auth documentation at /docs/ai-resources/mcp. It provides documentation search, examples, and setup guidance for use in MCP clients.
Better Auth Skills for agents
Better Auth provides portable instruction files called Skills, available at /docs/ai-resources/skills, that enable coding agents to follow Better Auth conventions.
Agent skills for Better Auth
Better Auth provides a skill pack for coding agents through the agent-skills framework. The skill pack is located in the better-auth/skills GitHub repository and teaches agents project conventions, safe patterns, and documentation locations.
Install Better Auth agent skills with npx
Install Better Auth agent skills using the command: npx skills add better-auth/skills. The skills CLI is installed via npx, so no global installation is required.
Agent skills load from project-level directory
After installing agent skills with npx, restart the agent or reload skills in your tool. Your editor or coding agent loads skills from its configured skills directory, which is often configured at the project level.
Add Better Auth MCP to Claude Code
Run 'npx auth@latest mcp --claude-code' to add the Better Auth MCP server to Claude Code. This runs 'claude mcp add' with the Better Auth URL; if it fails, the CLI prints the exact command to run.
Better Auth MCP server endpoint
Better Auth hosts a remote MCP server at https://mcp.better-auth.com/mcp that exposes documentation search, examples, and setup help to MCP-capable clients like Cursor, Claude Code, and Open Code.
MCP plugin versus MCP server distinction
The remote MCP server at https://mcp.better-auth.com/mcp is separate from the MCP plugin at /docs/plugins/mcp. The server is for consuming Better Auth documentation inside your editor or agent, while the plugin adds MCP provider authentication to your app.
Add Better Auth MCP to Cursor
Run 'npx auth@latest mcp --cursor' to open Cursor with a deeplink that automatically adds the Better Auth MCP server to your MCP configuration.
Add Better Auth MCP to Open Code
Run 'npx auth@latest mcp --open-code' to merge a 'better-auth' entry into opencode.json in the current directory with the remote MCP server URL.
Add Better Auth MCP manually
Run 'npx auth@latest mcp --manual' to write or merge mcp.json in the current working directory with a 'better-auth' entry containing {"url": "https://mcp.better-auth.com/mcp"}. For Cursor, add the same entry to ~/.cursor/mcp.json (user) or .cursor/mcp.json (project) using the HTTP server shape your Cursor version expects, then restart or reload MCP.
List supported MCP clients
Run 'npx auth@latest mcp' with no flags to list all supported MCP client targets.
Better Auth AI resources available
Better Auth provides AI resources including Ask AI in the documentation, LLMs.txt file at https://www.better-auth.com/llms.txt, a documentation MCP server at https://mcp.better-auth.com/mcp, and Skills for coding assistants.
