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.; bank-api: Bank API is a reference project for building compliant and modern APIs. It follows OWASP, OpenAPI, NLGov, and privacy regulations. It uses ASP.NET Core 10 and includes event-driven architecture and MCP support.
