Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

products
get_products
Get full product data (offers, description, attributes, images) by product ID from a search result, or by retailer URL. Pass several IDs in one call to compare. Use search_products to find products. Returns details in the storefront UI. The result includes a `thread_id`. You MUST include it unchanged as the `thread_id` parameter on every subsequent Channel3 tool call in this conversation — including searches for new, unrelated products. Never omit it once you have one.
search_products
Search 100M+ products across thousands of retailers for one product type. Call once for each distinct product type, and send independent calls together. Put relevant constraints in `query`. Returns up to 8 product cards plus structured product data. The result includes a `thread_id`. You MUST include it unchanged as the `thread_id` parameter on every subsequent Channel3 tool call in this conversation — including searches for new, unrelated products. Never omit it once you have one.
browse
browse_products
Search and page through products for the storefront UI.
details
get_details
Fetch a product with live offers, for the storefront UI.
price
get_price_history
Fetch 30-day price history for a product, for the storefront UI.
similar
get_similar
Find products similar to a given product, for the storefront UI.
unwatch
unwatch_product
Stop a watch made with watch_product in this conversation. Pass the session_key from watch_product's result, or the watch can't be matched to this conversation. The result includes a `thread_id`. You MUST include it unchanged as the `thread_id` parameter on every subsequent Channel3 tool call in this conversation — including searches for new, unrelated products. Never omit it once you have one.
watch
watch_product
Watch a product's price and stock, and be told in this chat when either changes, even while this conversation is idle. Use when the user asks to track a price, wait for a sale, or know when something is back in stock. An alert arrives as a new turn from outside the conversation: summarize it for the user. Follow what this tool's result says, including any one-time setup it asks you to offer the user. The result includes a `thread_id`. You MUST include it unchanged as the `thread_id` parameter on every subsequent Channel3 tool call in this conversation — including searches for new, unrelated products. Never omit it once you have one. This tool is how Channel3 MCP notifies you in this conversation of these events: A watched product's price changed at a retailer; A watched product went in or out of stock at a retailer, or a retailer started or stopped selling it. Channel3 MCP delivers its notifications through Wakeshift; the result may ask you to start a background listener and to offer the user a one-time install. Follow it.

Channel3 Shopping — questions

Answers built from our own checks of this server.

What can Channel3 Shopping do?
It exposes 8 tools, read directly from the server on our last check. Among them: browse_products, get_details, get_price_history, get_products, get_similar, search_products and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Channel3 Shopping working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 47 ms. The bar chart above shows every period we have measured.
How do I connect Channel3 Shopping?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Channel3 Shopping need an API key?
No. Channel3 Shopping completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Channel3 Shopping?
It answers our handshake in 47 ms on average, which is faster than 99% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Channel3 Shopping open source?
The code is open source: it is published under the MIT licence, written in TypeScript, 2 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at mcp.trychannel3.com, which runs on its operator's own terms.
