- Quickly create MCP servers in NestJS applications
- Manage multiple MCP Server instances
- Automatic SSE connection lifecycle handling
- Does not wrap native McpServer SDK methods
- Supports custom SSE and message endpoint names
Install the package alongside @modelcontextprotocol/sdk and zod. Import McpModule in your NestJS module and configure it with register, forRoot or forFeature. After registration, you can inject McpServerService to get a native McpServer instance (via getServer) and register tools with the SDK’s original API. SSE and message endpoints are automatically created.
