onetool-mcp vs obsidian-mcp-connector

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-connector: MCP Connector lets AI applications such as Claude Desktop, Claude Code, Cursor and VS Code securely access your Obsidian vault. The plugin hosts the MCP server inside Obsidian and runs semantic search entirely on-device.
