An MCP server that exposes a set of basic utility tools to AI agents.
概要
An MCP (Model Context Protocol) server that exposes a set of basic utility tools to AI agents: random value generation, arithmetic operations on numbers, comparisons for numbers, datetimes, and timespans, string manipulation, plus JWT validation and inspection. It communicates over the stdio transport and is built as a self-contained .NET application, so no .NET runtime needs to be installed on the target machine. One day I saw Opencode with Qwen3.8-27b take at least 5 minutes to determine if a JWT was expired or not. As LLMs are (in a very basic way to describe it) text generators, they can struggle with simple tasks that require calculations. So this MCP server provides basic tools to the agent that can be used to perform those tasks in a simple, correct and efficient manner instead of relying on an LLM's output and wasting tokens for somehting that might come out wrong anyways. - .

Basic Tools MCP Server
An MCP (Model Context Protocol) server that exposes a set of basic utility tools to AI agents: random value generation, arithmetic operations on numbers, comparisons for numbers, datetimes, and timespans, string manipulation, unit conversions, plus JWT validation and inspection. It communicates over the stdio transport and is built as a self-contained .NET application, so no .NET runtime needs to be installed on the target machine.
