FanZone 2026 · Engineering playbook

Every MongoDB query, agent tool, and MCP integration — with live "try it" links

Partner-track judges: This page is the source of truth for what FanZone actually does in MongoDB. Every capability below cites the real query/pipeline it runs, links to its line in the source code on GitHub, and offers a one-click "try it now" against the live deploy. There's no hand-waving.

🍃 The 7 MongoDB capabilities — each verified live on /healthz/detailed

🔧 14 custom agent FunctionTools — Gemini calls these directly

🌱 12 partner mongodb-mcp-server tools — via official MCP integration

FanZone wraps the official mongodb-mcp-server via Google ADK's McpToolset. Tool list is restricted to data-plane operations (no create-index / explain / atlas-*) to keep the agent inside Gemini's JSON-schema sanitizer.
