Channel3
Shop 100M+ products across thousands of US retailers: search, compare every store's live price, and switch variants (color, size) on inline product cards in Hermes Desktop. Portable Agent Plugins v1 package (mcp.json + skills/ + desktop/).
Good to know before installing
Connects to the hosted Channel3 MCP server at mcp.trychannel3.com (no account or key; free tier rate-limited per IP); search queries (and any image URL for visual search), product ids and variant selections go to it, and the Desktop cards call it directly from the app; a server-issued thread_id links searches within a conversation; product images load from cdn.trychannel3.com; Buy buttons open buy.trychannel3.com redirect links in the browser; nothing is purchased in-app and no credentials are stored.

How to install
- Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install channel3 - Said no? Turn it on later:
hermes plugins enable channel3 - Restart Hermes so it loads the plugin.
Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
