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.; foundryvtt-mcp: An MCP server that integrates with FoundryVTT, enabling AI assistants to roll dice, query game data, and generate content via natural language. It supports live connection via Socket.IO, provides MCP resources, and includes diagnostics when the REST API module is available. Installation is simple with npx or bunx, and it works with MCP-compatible clients like Claude Desktop and VS Code.
