SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and assets (resource) components.

What problem does it solve?

This Skill ensures secure handling of tokens in MCP servers by enforcing best practices for validation and storage, preventing common security vulnerabilities.

Core Features & Use Cases

  • Token Validation: Verifies JWT signatures, expiration, audience, issuer, and revocation status to maintain secure authentication workflows.
  • Secure Storage: Implements encrypted, memory-only, and short-lived token caching strategies to protect tokens at rest.
  • Use Case: When developing or reviewing MCP server implementations, utilize this Skill to ensure tokens are validated correctly and stored securely, reducing the risk of token-based attacks.

Quick Start

Use the secure token handling skill to evaluate a server’s JWT validation code.

FAQPage Schema
How do I validate JWT signatures and expiration in MCP servers?

To validate JWT authentication in MCP servers, enforce best practices by verifying token signatures, expiration times, audience, issuer, and revocation status to maintain secure authentication workflows and prevent token-based attacks.

What is the best way to securely store JWT tokens in memory?

The best way to securely store JWT tokens is by implementing encrypted, memory-only, and short-lived caching strategies, which protects tokens at rest and prevents unauthorized access to sensitive authentication data.

Do I need to check audience and issuer claims for JWT validation?

Yes, you need to check audience and issuer claims during JWT validation to ensure the token was issued by a trusted authority and is intended for your specific application, preventing unauthorized access through token misuse.

How does token revocation work with secure token handling?

Token revocation works by checking a token's revocation status during the validation process, ensuring that compromised or invalidated tokens are rejected before granting access to protected server resources.

Can I use in-memory caching for short-lived token storage?

Yes, you can use in-memory caching for short-lived token storage by implementing encrypted, memory-only caching strategies that keep tokens active temporarily while protecting them from exposure at rest.
