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 🙏

Enterprise MCP Gateway for Legacy Systems.

What MCP Bridge Is

A secure, zero-trust perimeter that safely exposes legacy REST, SOAP, and HTTP systems to autonomous AI agents utilizing the Model Context Protocol (MCP).

Why It Exists

Autonomous coding agents cannot be blindly trusted with internal network access or raw API credentials. This bridge acts as an isolation layer, translating agent intents into strict, policy-driven legacy requests.

Security Model

  • Zero-Trust Network: Employs Node's native DNS resolution to block SSRF, DNS rebinding, and 301-redirect attacks aimed at localhost, private subnets, or cloud metadata endpoints.
  • Credential Isolation: The AI agent never receives auth tokens. The Gateway maps credentialRef pointers to a secure backend provider before appending headers.
  • Agent Escrow Integration: Mutating endpoints (POST/PUT/DELETE) automatically halt execution and trigger ExternalAuthorizationProvider interfaces for human-in-the-loop approval.
  • Strict Output Constraints: Implements a hard 2MB payload ceiling to prevent memory exhaustion on edge nodes.

Multi-Tenancy & Audit

Full RBAC and tenant isolation are enforced at the request level. All operations produce structured, secret-scrubbed audit logs including execution latency and authorization decisions.

Installation

npm install @digital-mineral/mcp-bridge
