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.; simplenote-mcp-server: Simplenote MCP Server is a lightweight server that integrates Simplenote with Claude Desktop using the MCP Python SDK. It allows Claude Desktop to interact with Simplenote notes as a memory backend or content source. The server supports full note management, advanced search, high-performance caching, and secure authentication.
