onetool-mcp vs obsidian-sync-mcp
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-sync-mcp: Obsidian Sync MCP gives AI agents read/write access to your Obsidian vault via the Model Context Protocol. It supports filesystem mode (directly reading vault files) and CouchDB mode (via Self-hosted LiveSync). You can run it locally or deploy to the cloud for 24/7 availability.
