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.; teams-mcp: Teams MCP is a Model Context Protocol server that integrates with Microsoft Graph APIs to enable AI assistants to interact with Microsoft Teams, users, chats, channels, and files. It provides tools for authentication, user management, team and channel operations, messaging, file uploads, search, and media handling. The server supports OAuth 2.0 device code flow, read-only mode, and rich markdown formatting.
