How to connect Essentials
Essentials runs locally from a .NET package published to NuGet: FieldCure.Mcp.Essentials version 2.6.1. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs the .NET SDK; run as a .NET tool; the entry names dnx as the runtime. It reads these environment variables: ESSENTIALS_SEARCH_ENGINE, ESSENTIALS_SEARCH_API_KEY, SERPER_API_KEY, SERPAPI_API_KEY, TAVILY_API_KEY, WOLFRAM_APPID, ESSENTIALS_MEMORY_PATH, ESSENTIALS_DOWNLOAD_DIRECTORY and ESSENTIALS_SETTINGS_PATH; set them in the client's configuration for this server.
