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.; turbomcp: TurboMCP is a production-ready Rust SDK for the Model Context Protocol (MCP) with zero-boilerplate macros, modular transport architecture, and WASM support. It features compile-time schema generation, feature-gated transports, and a no_std core for edge and WASM deployment. The 25-crate workspace supports multiple transports including STDIO, HTTP, WebSocket, TCP, and Unix sockets, along with OAuth 2.1 and DPoP security.
