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.; swarmvault: SwarmVault turns raw files, URLs, and code into a persistent knowledge vault. Instead of losing work inside chat history, you get a markdown wiki, a knowledge graph, local search, and reviewable artifacts that stay on disk. It treats the vault itself as the product, writing durable artifacts you can inspect, diff, and keep improving.
