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.; teslamate-mcp: This server provides tools, prompts, and resources to query your TeslaMate database via MCP protocol. It supports both stdio and HTTP transports, with 20 tools for battery, charging, driving, efficiency, and locations.
