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.; recallium: Recallium is a persistent memory layer for AI coding agents, delivered as an MCP server. It provides typed, project-scoped memories that survive across sessions, with intelligent search tuned for engineering queries. It supports Claude Code, Cursor, Windsurf and other MCP-compatible tools.
