Secondhand MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 187 installs a week from npm. Last commit 6 Oct 2026.
Search Facebook Marketplace, eBay, Depop, and Poshmark from AI — filters, photos, full listings.
Today is the operative word: we check Secondhand MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
