onetool-mcp: OneTool MCP is a single MCP server that bundles 100+ tools — Brave search, Google, Context7, AWS, Playwright, Chrome DevTools, Excel, database operations, and more. Instead of registering each tool individually and burning context on their definitions, agents write short Python code to call any tool on demand. Anthropic engineering research backs this approach: code execution reduces token usage by over 98%, cutting costs dramatically when agents need many external tools.; mcp-engine-public: MCP Engine is an MCP server that enables AI assistants like Claude, Copilot, and ChatGPT to programmatically read and modify Power BI Desktop files. It allows users to query models, create measures, manage relationships, and optimize performance through natural language. The server runs locally with zero telemetry.
