MCP Server Marketplace

Model Context Protocol servers extend your AI coding agent with real capabilities — database access, API integrations, browser automation, and more. Every MCP server on RuleSell is security-scanned against OWASP Top 10, tested for graceful shutdown, and scored for quality.

Recent research found 36.7% of public MCP servers have SSRF vulnerabilities. That's why we scan every upload.
