Nothing serious here today

Today is the operative word: we check MatterCatalog every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

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

matter

check_matter_certification

Checks whether a product holds a Matter certificate on the CSA (Connectivity Standards Alliance) Distributed Compliance Ledger, using MatterCatalog's published read of the ledger (the same index as its "Is it Matter certified?" lookup page). Takes a product name, brand, model, part number or CSA certificate ID. Returns the matching ledger models with certificate IDs, certification dates, software and Matter versions, CSA device type and network (Thread, Wi-Fi or Ethernet), the date of the ledger read, and the MatterCatalog product page with that page's own certification answer and store names where one exists; also MatterCatalog pages for matching products that are not on the ledger (bridged or claim-only). No prices.

find_matter_devices

Lists Matter smart home products in MatterCatalog's catalog by category, platform, network and brand, with one line of facts each: the product page's certification answer (CSA certificate and date), network and whether it needs a Thread border router, the platforms its page lists, and the stores its page links (names only, no prices). By default only products sold in the US with a verified store link and a CSA certificate for the exact model. Includes the matching MatterCatalog buying guide's picks where one exists. Each product links to its MatterCatalog page.

catalog

catalog_stats

MatterCatalog's dated figures as sentences that carry their own date: how many Matter certified product models and companies are on the CSA Distributed Compliance Ledger (MatterCatalog's read of it), how many distinct certificates, how many models were newly certified in the latest ledger week and month, and how many products MatterCatalog lists and sells in the US by certificate, network and platform, each with the MatterCatalog page that shows it. No arguments.

compare

compare

Compares two products from MatterCatalog's catalog side by side: brand, category, the product page's certification answer with certificate and date, CSA device type and Matter version, network (and whether it needs a Thread border router), the platforms each page lists, where each is sold and the stores its page links (names only, no prices), with links to both pages and to MatterCatalog's side-by-side compare page.

where

where_to_buy

Names the stores MatterCatalog's product page links for one product (store links matched to the exact model, pack and region), with the product's certification answer and network, and links that page, where the store buttons, prices with their check times and the affiliate disclosure are. Store names only: no store URLs and no prices. Takes a brand and model, a MatterCatalog product ID or a mattercatalog.com/product/ URL.

MatterCatalog — questions

Answers built from our own checks of this server.

What can MatterCatalog do?

It exposes 5 tools, read directly from the server on our last check. Among them: catalog_stats, check_matter_certification, compare, find_matter_devices, where_to_buy. 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 MatterCatalog 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 512 ms. The bar chart above shows every period we have measured.

How do I connect MatterCatalog?

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 MatterCatalog need an API key?

No. MatterCatalog completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is MatterCatalog?

It answers our handshake in 512 ms on average, which is faster than 22% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
