Understanding Our MCP Quality Standards

Understanding Our MCP Quality Standards

Not all MCP servers are created equal. At MCP Directory, we believe in quality over quantity. Here’s how we ensure every server in our directory meets the highest standards.

Our Quality Criteria

1. GitHub Stars (10+ Minimum)

We require a minimum of 10 GitHub stars, but most of our featured servers have significantly more:

  • Major Platforms: 100-1000+ stars (Redis, Kubernetes, Elasticsearch)
  • Popular Tools: 50-200 stars (Sentry, Raygun, Firebase)
  • Emerging Projects: 10-50 stars (with strong potential)

2. Active Maintenance

Projects must show signs of active development:

  • Recent commits within the last 6 months
  • Responsive maintainers to issues and PRs
  • Regular updates and version releases
  • Clear roadmap for future development

3. Proper Documentation

Every server must have comprehensive documentation:

  • Clear README with setup instructions
  • Installation guides (npm, pip, etc.)
  • Configuration examples
  • Usage demonstrations
  • API documentation where applicable

4. Working Examples

We verify that servers include:

  • Demo implementations
  • Code samples
  • Integration tutorials
  • Real-world use cases

5. Community Engagement

Signs of a healthy community:

  • Active GitHub discussions
  • Issue resolution
  • Community contributions
  • User testimonials

Priority System

Tier 1: Official Company Servers

Highest Priority - Servers maintained by established companies:

  • AWS, Google, Microsoft cloud services
  • GitHub, GitLab development platforms
  • Slack, Discord communication tools
  • MongoDB, Redis database providers

Tier 2: High-Quality Community Projects

Medium Priority - Well-maintained community projects:

  • 50+ GitHub stars
  • Multiple contributors
  • Regular updates
  • Strong documentation

Tier 3: Emerging Quality Projects

Lower Priority - Promising new projects:

  • 10-50 GitHub stars
  • Single maintainer (but responsive)
  • Recent creation but active development
  • Unique functionality or niche use case

What We Don’t Include

We specifically exclude servers that:

  • Have fewer than 10 GitHub stars
  • Show no activity for 6+ months
  • Lack proper documentation
  • Have unresolved critical issues
  • Are abandoned or deprecated
  • Have security concerns

Verification Process

Our curation process includes:

  1. Automated Checks: Star count, commit history, package status
  2. Manual Review: Documentation quality, code structure
  3. Testing: Installation and basic functionality
  4. Community Research: User feedback, known issues
  5. Ongoing Monitoring: Regular re-evaluation of included servers

The Result

By maintaining these standards, we’ve built a directory of 165+ premium MCP servers with:

  • 250,000+ combined GitHub stars
  • 100% working GitHub links
  • Comprehensive metadata for each server
  • 16 organized categories
  • Multiple programming languages represented

Looking Ahead

Our goal is to reach 500 high-quality servers while never compromising on these standards. Quality curation takes time, but it ensures developers can trust every server in our directory.


Have a high-quality MCP server that meets these criteria? We’d love to hear about it!
