modelcontextprotocol/typescript-sdk
Official TypeScript SDK for building and interacting with Model Context Protocol (MCP) servers and clients, enabling standardized context provision for large language models.
rekog-labs/MCP-Nest
The project "rekog-labs/MCP-Nest" is a NestJS module designed to facilitate the creation of Model Context Protocol (MCP) servers. It enables developers to effortlessly expose AI tools, resources, and prompts from their NestJS applications. The module supports multiple transport types including Streamable HTTP, HTTP+SSE, and STDIO, providing flexibility in how MCP servers communicate. It features automatic discovery and registration of tools, resources, and prompts, which simplifies the development process. The module uses Zod for tool call validation, ensuring that inputs to tools are correctly validated. It also supports progress notifications, allowing tools to report their execution progress back to clients. Authentication is handled through NestJS Guards, enabling secure access to MCP endpoints. The module provides access to HTTP request information within MCP resources, which can be used for user identification and client-specific logic. The project includes detailed examples and quick start guides for both HTTP and STDIO transports, demonstrating how to define tools and resources, configure the module, and secure endpoints with authentication guards. It exposes several API endpoints for MCP operations, including SSE connections and tool execution endpoints, with support for stateful sessions in Streamable HTTP transport. The module is designed to integrate seamlessly with existing NestJS applications, leveraging dependency injection and familiar patterns. It also includes a playground directory with examples to test MCP features. Overall, this project is a comprehensive solution for building enterprise-ready MCP servers within the NestJS framework, focusing on ease of use, flexibility, and security.
