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 🙏

mcp-healthcheck

Trust-score scanner for MCP servers. Lighthouse for the Model Context Protocol.

Evaluate MCP servers on liveness, schema validity, security, freshness, tool quality, and documentation to output an objective, multi-dimensional trust score.

Features

  • Scoring Engine: Calculates a 0-100 overall score based on 7 heavily-weighted categories.
  • Deep Validation: Tests SSRF vulnerabilities, TLS configurations, and validates tool JSON schemas.
  • Reporting: Exports detailed findings in JSON, HTML (with charts), and Markdown.
  • Shields.io Badges: Instantly generates trust badges for your README.
  • Continuous Monitoring: Run in background mode to record stability over time using SQLite.

Installation

npm install -g @siddharthasingh/mcp-healthcheck

Quick Start

Scan an MCP server via Stdio:

mcp-healthcheck scan "npx -y @modelcontextprotocol/server-postgres"

Scan an MCP server over HTTP/SSE:

mcp-healthcheck scan https://example.com/mcp

Generate a visually rich HTML report:

mcp-healthcheck report --format html > report.html

Get a Markdown badge for your README:

mcp-healthcheck badge <server-id>

Scoring Categories

The trust score is a weighted sum of the following:

  1. Liveness (20%): Handshake time, connection success, response latency (P50/P95).
  2. Schema Validity (15%): Adherence to the official JSON Schema spec.
  3. Security (25%): TLS verification, SSRF protections, Secrets leakage.
  4. Freshness (10%): Repository activity and commit recency.
  5. Tool Quality (15%): Descriptions, example usages, error handling.
  6. Docs (10%): Presence of .well-known/mcp.json and install instructions.
  7. Behavior (5%): Rate limits, idempotency.
