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.; lsbot: lsbot is a lean and secure AI bot with end-to-end encryption by default, zero-dependency single binary, local-first data storage, and cloud relay for easy integration with WeChat Work, Feishu, DingTalk, etc.
