Description

nest-mcp is a framework that enables developers to create MCP servers, clients, and gateways with familiar NestJS patterns such as decorators, dependency injection, and modules. It supports multiple transport layers like HTTP, SSE, and STDIO, and provides features including authentication, resilience, aggregation, and health checks. This modular architecture facilitates building scalable AI tool/resource/prompt services and aggregating multiple upstream MCP servers behind a unified endpoint.
