onetool-mcp vs civ6-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.; civ6-mcp: This MCP server connects MCP-compatible clients to a running Civilization VI game, providing 70+ tools for units, cities, diplomacy, and more. Agents can read game state, make decisions, and end turns through the game's rule-enforcing APIs. It serves as a benchmark for evaluating LLM strategic reasoning over multi-turn games.
