mcp-marketplace

The application demonstrates high security awareness, utilizing bcryptjs for password hashing, JWT for authentication, and retrieving all sensitive credentials from environment variables. The middleware applies comprehensive security headers (CSP, XSS, Frame Options, Referrer Policy, Permissions Policy, CORS) and implements rate limiting per IP and endpoint. The core MCP message router currently returns mock responses, which inherently limits direct execution risks. Future plans for hosted MCPs detail robust sandboxing, resource limits, and container isolation, indicating a strong commitment to security for dynamic execution. Minor deduction for the current design choice of allowing unauthenticated access for 'public servers' in the MCP gateway, although it's within expected design parameters for an open marketplace and not a direct vulnerability in the current mock implementation.
