Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

mcpaccess-auth0-express

Secure your Model Context Protocol (MCP) server in minutes — Auth0-powered Express middleware with JWT validation and role-based access control for tools, resources, and prompts.

Overview

mcpaccess-auth0-express provides a straightforward way to integrate Auth0 authentication into an Express-based MCP server. It is designed for developers who need to protect MCP endpoints (tools, resources, and prompts) without adding unnecessary complexity.

This package handles:

  • JWT verification using Auth0’s public keys.

  • Role-based access control (RBAC) for fine-grained permissions.

  • Express middleware integration with minimal configuration.

  • MCP-specific endpoint protection for tools, resources, and prompts.

When to Use

Use this package if:

You’re building an MCP server in Node.js with Express.

You want to authenticate and authorize users via Auth0.

You need to restrict access to specific MCP actions based on roles or claims.

You prefer a plug-and-play middleware over custom auth code.

Features

Plug-in Express middleware for MCP endpoint protection.

Supports Auth0 RS256 token validation.

Role and scope checks for different MCP actions.

Works alongside other Express middleware.

Minimal boilerplate — focus on your MCP server logic, not on token handling.
