WhatBin: Source-Backed Waste Guidance with Sanity Context MCP
Description and use
WhatBin delivers evidence‑based waste disposal guidance for Hanoi and Ho Chi Minh City, leveraging Sanity’s structured content and Context MCP to ensure answers are grounded in official rules and not hallucinated by the model.
Problem
Users in Hanoi and Ho Chi Minh City need reliable, city‑specific disposal instructions for household items, but existing guidance is fragmented and hard to access.
Outcome
WhatBin delivers evidence‑based disposal guidance, clearly indicating when rules apply, when coverage is missing, or when conflicts exist, without the AI generating unverified instructions.
Workflow
- Describe or upload an item
- Select city and confirm item
- Retrieve and display matched rule or status
- Show explanation with evidence
- Allow follow‑up questions or cross‑city comparison
Evidence
WhatBin helps people in Hanoi and Ho Chi Minh City figure out how to dispose of household items properly.
The AI should explain the guidance, not decide what the guidance is.
Published content in Sanity determines which disposal instruction applies.
The agent receives: the user's question, a limited amount of conversation history, the selected item, the relevant city, the date, the verified resolver result.
For a MATCHED result, the agent explains why the reviewed rule applies and which evidence supports it.
