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.

onetool-mcp is currently grouped under API Integration, which makes it easier to evaluate through workflow fit instead of isolated features alone. Based on the available data, it leans most heavily toward 100+ tools in one MCP server: search, AWS, Playwright, databases, Excel, and more and Cutting MCP token overhead when an agent needs 10+ external tools. The listed license is GPL-3.0, which is useful when adoption constraints matter. It also shows measurable community traction with 22 GitHub stars.
