Auth0 MCP Server

** This is a POC that isn't fully implemented and should not be used for production workloads or any tenant you do not want an LLM to have access to.

A ModelContextProtocol (MCP) server implementation for Auth0 that enables Language Models to interact with Auth0 resources securely.

Overview

The Auth0 MCP Server acts as a bridge between Language Models (LLMs) and Auth0's Management API. It implements the ModelContextProtocol specification to provide a secure, structured way for LLMs to create, read, update, delete, and search Auth0 resources.

This server enables AI assistants to help manage your Auth0 tenant by providing natural language interfaces to Auth0 operations, enhancing productivity and simplifying resource management.

Features

• Auth0 Resource Management: Interact with clients, users, forms, and other Auth0 resources
• Secure Access Control: Enforces proper authentication and authorization
• ModelContextProtocol Compliant: Compatible with LLMs that support the MCP specification
• Comprehensive Operations: Create, read, update, delete, and search functionality for resources
• Stateless Design: No server-side session storage required
• Detailed Logging: Comprehensive activity tracking for security monitoring
• Customizable Permissions: Fine-grained access control per resource type

Installation

# Clone the repository
git clone https://github.com/yourusername/a0-mcp.git
cd a0-mcp

# Install dependencies
npm install

Configuration with Claude Desktop

This project can be used with Claude Deskop. To configure Claude Desktop you must edit the claude_desktop_config.json file. You can find this file in Claude Desktop under the file menu Claud >> Settings. A new window will open up. Select the navigation item called Developer. at the bottom hit the Edit Config button. A file explorer window will open up where you can find the claude_desktop_config.json to open in a text editor.

  "mcpServers": {
    "auth0": {
      "command": "node",
      "args": [
        "/path/to/repo/a0-mcp/dist/index.js"
      ],
      "env": {
        "AUTH0_DOMAIN": "<auth0-domain>",
        "AUTH0_CLIENT_ID": "<client-id>",
        "AUTH0_CLIENT_SECRET": "<client-secrete>"
    }
  }
}

It is recommended that you create a M2M Client in Auth0 Tenant. Using the Client ID and Client Secret the MCP Server will do the necessary authentication for the LLM to interact with your auth0 tenant. You can control the scopes inside your M2M Client to restrict what access you want to give the LLM via the MCP Server.

Usage

Building the MCP Server

# Go to the root directory of the a0-mcp repository
cd 

# Builds the MCP Server in the ./dist directory
npm run build

Once the MCP Server is build you can import this into Claude Desktop. All the necessary files are built and published to the dist directory in the root director of the local a0-mcp repository.

Available Operations

The MCP server supports the following operations for Auth0 resources:

• Create: Add new resources to your Auth0 tenant
• Read: Retrieve information about existing resources
• Update: Modify properties of existing resources
• Delete: Remove resources from your Auth0 tenant
• Search: Find resources matching specific criteria

API Reference

Clients

Operation	Description	Required Parameters
listClients	Retrieve all clients	None
getClient	Get a specific client	client_id
createClient	Create a new client	name, app_type
deleteClient	Delete a client	client_id
searchClients	Search for clients	query

Users

Operation	Description	Required Parameters
listUsers	Retrieve all users	None
getUser	Get a specific user	user_id
getUserByEmail	Get a specific user by email	user_email
createUser	Create a new user	email, password

Forms

This is a work in progress and not fully implemented.....

Operation	Description	Required Parameters
listForms	Retrieve all forms	None
getForm	Get a specific form	form_id
createForm	Create a new form	name, fields
updateForm	Update form properties	form_id, properties to update
deleteForm	Delete a form	form_id

Authentication

The server supports the following authentication methods:

1. OAuth 2.0 Client Credentials: For server-to-server communication
2. Bearer Token: For authenticated API calls
3. API Key: For simplified access (less secure, use with caution)

Example authentication with Bearer token:

curl -X POST https://your-server.com/mcp/clients/list \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Content-Type: application/json"

Security

The Auth0 MCP Server implements several security measures:

• Rate Limiting: Prevents abuse and DoS attacks
• Input Validation: Sanitizes all incoming data
• Scoped Access: Enforces least privilege principle
• Audit Logging: Records all operations for review
• Transport Security: Requires HTTPS for all communications

Examples

Here's an example of how an LLM might interact with the MCP server...
