MKMTool vs. Hoard

Get the honest answer out of the way first: Hoard does not support Cardmarket. If you're looking for something to replace MKMTool, this page cannot claim to be it. Hoard only reprices TCGplayer listings. If Cardmarket is where you sell, the tool worth reading about next is TCG PowerTools, which is actively maintained and built specifically for Cardmarket sellers. Hoard is only relevant to you if you also sell on TCGplayer and want that side automated — it isn't a substitute for MKMTool on Cardmarket.

Why MKMTool earned its reputation

MKMTool is free and open source under the AGPL-3.0 license. Its pricing engine (the tool calls the algorithm "TOSS") traverses the competing listings on Cardmarket to work out a price, rather than applying a flat percentage-off-market rule. That's a genuinely more sophisticated approach than most free pricing tools attempt, and it's the reason MKMTool built the reputation it has among Cardmarket sellers. Being free, open source, and technically well built is a real, specific combination — most tools in this space pick one or two of those, not all three.

An AGPL-3.0 license also means the source is available for anyone to read, audit, or modify — a level of transparency a paid, closed tool doesn't offer. For a seller deciding whether to trust a pricing algorithm with a live storefront, being able to see exactly what the algorithm does, rather than taking a vendor's word for it, is a real advantage on its own.

Why it's a risk to rely on now

MKMTool's last release was v0.8.2.2, on January 21, 2024. As of August 2026, that's over two and a half years without an update. For a tool whose whole job is matching a live, moving marketplace, that gap matters — Cardmarket's own site and API can and do change, and a tool that isn't shipping isn't tracking those changes.

It's also Windows-only, and it requires you to bring your own Cardmarket API credentials to run it — not a hosted service, but a piece of software you run yourself against your own account. None of that makes the TOSS algorithm less well designed. It does mean you're running unmaintained software against a live marketplace API, with no one patching it if something on Cardmarket's side breaks it.

Open source software doesn't stop working the day the last commit lands. The AGPL-3.0 license means anyone could, in principle, fork the project and pick up maintenance. As of this writing that hasn't happened in a way that's changed the two-and-a-half-year gap since v0.8.2.2. If you're currently relying on MKMTool and it's still matching Cardmarket's site correctly, that's worth verifying rather than assuming — a tool that hasn't been updated since January 2024 has had a lot of time for the marketplace underneath it to shift.

Where that leaves you

If Cardmarket is your primary or only marketplace, the tool to look at is TCG PowerTools — it's built for Cardmarket specifically and it's still being actively maintained, which MKMTool currently is not. Hoard has no Cardmarket integration at all, shipped or planned on a public timeline, so it isn't an alternative for that side of your business.

Hoard becomes relevant only if you also run a TCGplayer store alongside Cardmarket. In that case, Hoard's scheduled repricing can handle the TCGplayer side: floors and ceilings, watch-only preview, weekly receipts. Your Cardmarket pricing stays with MKMTool, TCG PowerTools, or whatever you move to there. The two aren't in competition; they'd be covering two different marketplaces for the same seller.

If you're a Cardmarket seller looking for MKMTool's replacement, that's TCG PowerTools, not this page. If you sell on TCGplayer too and want that side handled, the section below is for you.
