## What it does

This MCP server searches Facebook Marketplace, eBay, Depop, and Poshmark. Filter listings by price, category, condition, size, or color, then request more information about a result using its listing ID. Facebook searches can also use a city and radius.

eBay searches need API credentials. Depop and Poshmark rely on Chrome or Chromium; if neither browser is available, those two sources are skipped while the others can still run. That matters if either marketplace is central to your search. Use the `MARKETPLACES` environment variable to choose which sources are active.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `EBAY_CLIENT_ID`, `EBAY_CLIENT_SECRET`, `EBAY_MARKETPLACE_ID` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
