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.; opencode-studio: OpenCode Studio is a local GUI for managing OpenCode configurations. It provides an intuitive interface for toggling MCP servers, editing skills, managing plugins, and handling authentication without editing JSON files directly. The tool also supports profiles, bulk imports, usage dashboards, and GitHub sync.
