A Swiss Army knife MCP server that bundles 20 general-purpose tools into a single .NET global tool. You get HTTP requests, Bing web search (free, no key), web page fetching with HTML-to-Markdown conversion, shell command execution, sandboxed JavaScript via Jint, file I/O with document parsing (PDF, DOCX, PPTX, XLSX), and SQLite-backed persistent memory. Optional API keys unlock Serper, Tavily, or SerpApi for category search (news, images, scholar, patents) and more reliable results. Web fetch and downloads include SSRF protection. Document parsing extracts text layers only, no OCR. Install once with dotnet tool install, configure your search engine and Wolfram|Alpha key if needed, and you're ready to script across web, file system, and computational knowledge in any MCP client.
