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:
- Automated Checks: Star count, commit history, package status
- Manual Review: Documentation quality, code structure
- Testing: Installation and basic functionality
- Community Research: User feedback, known issues
- 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!
