MCP registry audit benchmark

This page benchmarks 33 mcp registry apps on the Slack Marketplace marketplace against a fixed listing-quality rubric. Each audit checks 12 categories — title clarity, description completeness, screenshot count and resolution, categorization accuracy, supported languages, integration breadth, pricing-tier disclosure, support contact availability, and more. Scores range 0–100; apps in the mcp registry space typically cluster in the 50–70 range based on the sampled top 10. AppRanks runs the rubric independently of the marketplace — we do not accept payment from developers to influence audit scores, and the same rubric is applied to every listing on the platform regardless of partnership status. The full methodology, rubric weights, and scoring formulas are documented on our methodology page. Audits are recomputed every 24 hours from the canonical Slack Marketplace listing, so the snapshot here is at most one refresh cycle behind the live data.
