MCP Marketplace Built with Claude Code Features Security Scanning and Monetization

mcp-marketplace.io is a curated marketplace for discovering and installing MCP (Model Context Protocol) servers, built almost entirely with Claude Code. The developer reports that Claude Code wrote roughly 95% of the codebase, with the developer steering architecture and testing while Claude built components from the security scanning pipeline to payment integrations.

Key Features

• Browse 2,200+ MCP servers pulled automatically from the official registry at modelcontextprotocol.io. Users can search by category and sort by stars or security score.
• Security scanning for every server through multiple layers before listing. Full reports and findings are visible on every page, with hundreds of servers rejected for failing scans.
• One-click install for 7 clients: Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Codex, and ChatGPT. Users pick their app and get the configuration.
• Creator monetization with one-time or subscription pricing, direct payouts to creators, and license key management. This is described as the first marketplace to support actual commerce for MCP.
• Reputation system with uptime tracking, review scores, security history, update frequency, all rolled into a grade per creator.

Differentiation from Other Directories

The developer states that other MCP "marketplaces" are just lists of GitHub links that stop at discovery, while this implementation adds payments, security scanning, license keys, creator payouts, and install configs that work across clients. The official registry is described as a metadata layer, while this marketplace is the product layer on top.

The service is free to browse and install, with paid tiers existing only for creators who want to sell their servers.
