TengineAI

TengineAI is a hosted remote MCP server platform that connects AI assistants to external APIs and services, solving the complexity of building and managing MCP servers, OAuth flows, and API key management. It targets developers using MCP clients like Claude Desktop, Cursor, and VS Code, as well as teams building AI-powered applications. The platform provides a production-ready runtime with scoped authentication, permission enforcement, and execution logging, differentiating itself by handling the execution layer between agents and real-world systems.
