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-India-Stack: MCP server exposing Indian financial and government APIs for AI agents. Zero authentication required and operates offline-first. It provides tools for bank branch lookup, GST validation, tax calculations, and various Indian document validations.
