An end-to-end demo of an AI agent triaging a payments performance incident via the MongoDB Remote MCP plugin: a slow checkout status-poll query (missing index) is diagnosed with explain() and the Atlas Performance Advisor, fixed with a compound index, and verified. - seed_payments.py: seeds a realistic ~300k payments collection (no index on session_id; sized so a COLLSCAN is ~4s warm / ~30s cold, under the MCP 60s cap) - generate_load.py: trickle load to keep the Performance Advisor recommendation fresh and the cache warm - post_alert.py: posts an Atlas-styled Query Targeting alert to Slack - README.md: story, setup, run, and reset/reseed instructions
Local-first LangGraph inventory monitoring demo for a coffee roaster: - FastAPI backend with MongoDB-backed products, inventory, suppliers, POs, alerts, chat, and an agent-activity event log - Light Stocky/Shopify-style UI with MongoDB green accents: tabbed sidebar nav, red notification badge on the Inbox, accordion alert detail with chat - Agent-activity feed surfaces the monitor's thinking/plan steps and the actual MongoDB commands (find/aggregate/updateOne) it runs - Seeded catalog of 9 SKUs with shared packaging components .env is gitignored; use env.example for setup.
