@vibelogin/mcp

Add authentication to your app without leaving your IDE. MCP server for Cursor, Claude Code, Windsurf, and Cline.

Just say "add authentication to my app" — the agent creates your project, configures auth methods, wires up Google OAuth, and scaffolds a working sign-in flow into your codebase. All from your editor's chat.

---

Install

No global install needed. Wire it into your MCP client config once and it runs on demand via bunx.

---

Client configuration

One snippet works in every client. Paste this into your MCP settings and you're done.

{
  "mcpServers": {
    "vibelogin": {
      "command": "bunx",
      "args": ["@vibelogin/mcp"]
    }
  }
}

The first tool call opens a browser for one-click consent. After that, tokens are cached under ~/.vibelogin/credentials.json — you won't be asked to log in again for 30 days.

Claude Desktop / Claude Code

~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

{
  "mcpServers": {
    "vibelogin": {
      "command": "bunx",
      "args": ["@vibelogin/mcp"]
    }
  }
}

Cursor

~/.cursor/mcp.json (or per-project .cursor/mcp.json):

{
  "mcpServers": {
    "vibelogin": {
      "command": "bunx",
      "args": ["@vibelogin/mcp"]
    }
  }
}

Windsurf / Cline / Zed

Same shape — every MCP client accepts a command + args block. The one-liner above works in all of them.

That's it — no environment variables needed. Defaults point to production automatically.

---

Authentication

On first use, a browser window opens for one-click consent. After that, you're authenticated for 30 days — no further prompts.

---

Tools

The agent picks the right tools automatically based on your conversation. Just say what you need.

create_project

Creates a new VibeLogin project in your org. Returns the project's id, slug, oauthSlug, environment, publishable key, and secret key (shown once).

Param	Type	Required	Description
name	string	yes	Human-readable project name.
slug	string	no	URL-safe slug; auto-generated from name if omitted.
environment	enum	no	production | development | staging (default production).

list_projects

Lists every project in your org. Use this when the agent needs to discover what already exists before creating something new.

No parameters.

get_project

Look up a single project by id, slug, or oauthSlug.

Param	Type	Required	Description
idOrSlug	string	yes	Project id, slug, or oauthSlug.

configure_auth

Toggle auth methods, set redirect URLs, and/or wire up Google OAuth. Field-level updates — anything you don't set is left untouched.

Param	Type	Required	Description
projectId	string	yes	The project's id.
methods.emailPassword	boolean	no	Enable email + password sign-in.
methods.magicLink	boolean	no	Enable magic link emails.
methods.emailOtp	boolean	no	Enable 6-digit email OTP codes.
methods.passwordReset	boolean	no	Enable password reset emails.
methods.emailVerification	boolean	no	Require email verification on signup.
google.clientId	string	with google	Google OAuth client ID (from Google Cloud Console).
google.clientSecret	string	with google	Google OAuth client secret.
google.enabled	boolean	no	Default true.
redirectUrls	string[]	no	Overwrites the project's allowed redirect URL list.

If you call this without google, the response includes the exact Google Cloud Console URL + redirect URI you need to set up the credentials.

add_auth_to_project

Scaffold a working sign-in flow into your codebase. Detects the framework from package.json and writes non-destructive files (existing files are skipped, never clobbered).
