# How to Monitor Regional Resale Inventory with Copilot

Track used inventory across marketplaces and regions without manually rerunning the same search on every site. Start with `source_coverage`, `search_listings`, `listing_details`, and `watchlist_snapshot` to get the raw material. Copilot fits best when the output needs to become structured sourcing data, a workspace artifact, or a reusable monitoring file immediately.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Connect ToolRouter in Copilot: {"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}
2. State the schema and sourcing rules you want back in the workspace: set the item, acceptable condition, target regions, shipping or pickup constraints, and whether you care about classifieds, auctions, or both.
3. Run `source_coverage`, `search_listings`, `listing_details`, and `watchlist_snapshot` through `marketplace-search` and keep source, price-text, location, and listing-class fields explicit.
4. Ask Copilot to turn the result into structured JSON, CSV-ready rows, or markdown notes. Focus on source coverage, price range, listing quality, local-pickup relevance, and whether the listing looks like real inventory or search noise.
5. Drop the result into a sourcing watchlist, procurement note, or recurring inventory monitor.

## Example Prompt

```
Use marketplace-search to monitor used Sony A7 III inventory across the UK and EU. Check source coverage first, search listings with a used-only bias, preview the strongest offers, and build a compact watchlist snapshot. Return structured JSON plus markdown notes I can save into the workspace for weekly tracking.
```

## Tips

- Run source coverage first when you are entering a new region so you know which marketplaces are actually in play.
- Bias toward condition, pickup, and region filters early or the watchlist will fill with low-quality noise.
- Ask Copilot to normalize the same source and location fields every run so watchlist diffs stay easy to compare.
