onetool-mcp vs obsidian-mcp-server

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.; obsidian-mcp-server: The Obsidian MCP Server acts as a bridge, allowing applications (MCP Clients) to interact directly and safely with your Obsidian vault. It enables AI assistants and development tools to automate vault management, integrate Obsidian into AI workflows, and build custom tools by leveraging the Obsidian Local REST API plugin.
