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-google-sheets: mcp-google-sheets is a Python-based MCP server that bridges AI assistants with Google Sheets. It provides a comprehensive set of tools for spreadsheet operations, supports multiple authentication methods, and can be easily deployed with uvx. Ideal for automating data workflows and natural language interaction with spreadsheets.
