AuthAction is a flexible auth platform for both frontend and M2M apps. It supports OAuth2, social logins, passkeys, and includes user, role, and org management. Scalable up to 1M MAUs for free, it’s ideal for startups and enterprises alike.
The Model Context Protocol (MCP) lets AI agents interact with external tools and data sources, but what happens when you need to secure these interactions? Here’s how to add robust authentication to your MCP servers using AuthAction.
The Problem
MCP servers often need to:
- Authenticate AI agents dynamically
- Control access to specific resources
- Handle multiple clients without manual setup
- Audit all interactions
Traditional auth flows weren’t designed for AI agents that need flexible, dynamic access.
AuthAction’s MCP Solution
AuthAction provides a security layer specifically for MCP servers with:
- Dynamic Client Registration: Clients can register themselves automatically
- Fine-grained Access Control: Control what resources each agent can access
- Session Management: Secure token handling with auto-refresh
- Real-time Monitoring: Track all agent interactions
Quick Setup
1. Enable Dynamic Registration
In your AuthAction dashboard:
Settings > Advanced > Enable Dynamic Client Registration
2. Configure API Access
For your MCP API Resource server:
Applications > APIs > [Your MCP Server] > Dynamic Clients > Enable Dynamic Client Access
Security Considerations
- Production: Use dynamic registration cautiously in production
- Connections: Limit which auth connections are available
Example Implementation
Check out the mcp-server-auth-example repository for a complete working implementation.
Why This Matters
As AI agents become more sophisticated, they need secure access to sensitive resources. AuthAction’s MCP authorization provides:
- Zero-config onboarding for new clients
- Enterprise-grade security for production deployments
- Developer-friendly integration with existing MCP servers
- Comprehensive auditing for compliance
Getting Started
- Sign up for AuthAction
- Enable dynamic client registration
- Configure your MCP API Resource server
- Integrate the SDK
- Deploy securely
The combination of dynamic registration and fine-grained access control makes it easy to secure MCP servers without sacrificing flexibility.
