What is MCP Server NestJS Module Library?

MCP Server NestJS Module Library is a modular library for building Model Context Protocol (MCP) servers using NestJS. It provides decorators, modules, and integration patterns to expose MCP resources, tools, and prompts in a scalable, maintainable way. It wraps the official @modelcontextprotocol/sdk and stays compatible with its types and specification.

How to use MCP Server NestJS Module Library?

Install the package along with peer dependencies (@nestjs-mcp/server, @modelcontextprotocol/sdk, zod). Register the MCP server globally with McpModule.forRoot or McpModule.forRootAsync in your root module, providing a name and version. Define capabilities using @Resolver, @Tool, @Resource, and @Prompt decorators. Use McpModule.forFeature in feature modules to organize large servers.

Key features of MCP Server NestJS Module Library

  • Decorators for MCP resources, tools, and prompts.
  • Global registration via McpModule.forRoot and forRootAsync.
  • Feature module registration with McpModule.forFeature.
  • Guard support at global, resolver, and method levels.
  • Session management and configurable transport options (SSE, stdio).
  • Wraps the official @modelcontextprotocol/sdk for compatibility.

Use cases of MCP Server NestJS Module Library

  • Expose database records as read‑only MCP resources.
  • Provide AI‑callable tools for external actions or computations.
  • Organize a large MCP server into separate feature modules.
  • Build a maintainable, testable MCP server within a NestJS application.

FAQ from MCP Server NestJS Module Library

What is MCP?

The Model Context Protocol (MCP) is an open protocol for connecting LLMs to external data, tools, and prompts.

What are the runtime dependencies?

You need @nestjs-mcp/server, @modelcontextprotocol/sdk, and zod installed.

How do I configure the server name and version?

Pass name and version (and optionally instructions, capabilities, logging, transports, and protocolOptions) to McpModule.forRoot.

Can I use guards with MCP capabilities?

Yes. Guards can be applied globally, at the resolver (class) level, or at the method level. MCP execution context is available via McpExecutionContext.

What transport options are available?

The library supports SSE and stdio transports. You can disable SSE by setting transports: { sse: { enabled: false } } in the module options.
