onetool-mcp vs toolhive-catalog
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.; toolhive-catalog: ToolHive Catalog is a registry of MCP servers and skills that provide AI assistants with specialized tools and reusable prompts. It supports both container-based and remote servers, with a structured JSON format for registration. Skills are defined as markdown files with YAML frontmatter, enabling repeatable workflows.
