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.; onlyboxes: Onlyboxes is a self-hosted code execution sandbox platform for individuals and small teams. It uses a control-plane and execution-plane architecture, supports horizontal scaling and multi-language heterogeneous runtimes. It provides REST APIs and MCP tools for executing Python code and stateful terminal sessions.
