Essentials

Overview

Essentials is an MCP server that bundles core utilities for AI assistants: HTTP requests, web search, file downloads, Wolfram|Alpha queries, shell execution, JavaScript evaluation, file I/O, and memory management. Install it locally via dnx FieldCure.Mcp.Essentials --yes to expose all these tools to Claude, Cursor, VS Code, and other MCP clients.

The server runs on your machine as the NuGet package FieldCure.Mcp.Essentials, communicating over stdio. It requires an API key for authentication. Version v2.6.1 is published under the MIT license with full source code available at fieldcure/fieldcure-mcp-essentials on GitHub.

Essentials appears in the Memory category on mcp.site and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP-compatible tools. If you maintain this server, claim your listing to earn a Verified badge and keep information up to date.
