Manage your Magic collection with Claude or ChatGPT
What happens when you connect an AI assistant to your Tomebound collection, with example requests and what each one does.
Tomebound has an MCP server, a standard way for AI assistants to use outside tools. Once you connect it to Claude or ChatGPT, the assistant can read your collection and, if you allow it, make changes: add cards, import lists, build deck recipes, check prices, move cards between containers, and undo its own changes.
What connecting does
You add Tomebound in your assistant's connector or plugin settings, sign in to Tomebound, and approve the access on Tomebound's consent page. Tomebound is listed in Claude's connectors directory. In ChatGPT, you add it as a custom MCP server for now. The setup guides have the exact steps for each assistant. Menus and availability depend on your plan and workspace settings.
A connection starts with read access. Changes need write access, which the assistant has to request and you have to approve. If you don't have a Tomebound account yet, you can sign up during the connection flow. You can revoke a connection at any time under Settings → Connected apps.
How changes stay safe
- Previews. Imports and new decks always start as a preview. So does any change that removes cards, decks, or containers or touches more than 25 rows: Tomebound refuses to apply it until the assistant repeats the request with that preview's token. Smaller adds and edits can apply in one step. Whether the assistant shows you the preview first is up to the assistant, so ask it to.
- Exact matching. Card, set, deck, and container names are matched literally, ignoring only case, accents, and extra spaces. A misspelled or near-miss name returns suggestions for you to choose from. Tomebound never guesses.
- Undo and recovery. Tomebound saves a recovery point before every change an assistant applies, and the assistant can undo its last change as one unit.
Example requests
Add cards
Add two near mint, nonfoil Sol Rings to my trade binder.
The assistant looks up the printings. If more than one printing matches, it shows you the candidates with set and collector number and asks which one you have. If you leave out the quantity, finish, or condition, it asks for them. If you have no container called trade binder, it asks before creating one.
Import a list or a CSV
Import this Moxfield export into a container called Binder 2. Show me the preview first.
Attach the file or paste the list. The preview shows the matched printings, how many rows go where, any container that will be created, warnings, skipped rows, and an estimated value in US dollars. Rows that don't resolve to a printing are left out and listed. Nothing is saved until the preview is confirmed, and the whole import becomes one change you can undo. An import can hold up to 5,000 rows, and public Moxfield and Archidekt deck links work too.
Check a deck against what you own
Here's a decklist. Which cards do I already own, and what would the rest cost?
Tomebound compares each card with your collection. It separates copies you have free from copies already in another deck, which it names, and lists the cards you don't own in any printing. The buy list includes Scryfall price estimates and purchase links. The estimates are not live offers from sellers.
Build a Commander deck
Build a Commander deck around Atraxa, Praetors' Voice from cards I own, check that it's legal, and save it as a deck.
The assistant chooses the cards, using Tomebound to search your collection. Before saving, it can check the list against the format's rules: legality, singleton, color identity, deck size, and the commander itself. Saving creates a deck recipe from a preview. A recipe is a plan, not a move: it doesn't add or move any of your cards, and it never overwrites an existing deck.
Ask what the collection is worth
What's my collection worth, and which cards moved the most this month?
You get a total in US dollars, euros, or MTGO tix, with counts of priced and unpriced cards and your most valuable cards. Tomebound records your collection's value daily, so it can also report the change over a range and the cards whose prices moved most over 7, 30, or 90 days, or a year. History starts on the first day it was recorded. Cards without a price are counted as unpriced, never as $0.
Move cards between containers
Move my Rhystic Study and both copies of Cyclonic Rift from the bulk box to my staples binder.
The assistant finds the copies and moves them. If the destination doesn't exist, it asks before creating it. A move of more than 25 rows needs a confirmed preview.
Undo a change
Undo that last change.
Tomebound reverses the assistant's last change as one unit, including every card in a bulk change, as long as you haven't changed those cards since. If you have, the undo stops and points to the recovery point saved before that change, which the assistant can preview and restore. Recovery points from changes of more than 25 rows are kept for up to 30 days.
Export your collection
Export my collection as a ManaBox CSV.
Tomebound creates a Tomebound, Moxfield, or ManaBox CSV, or a JSON file, of all your cards or of one container or deck. Small files come back in the conversation; larger ones come as a private download link that expires after 15 minutes.
What it won't do
No tool makes purchases or payments. A read-only connection can't change anything. The assistant can only use the tools you've enabled in your client, so some requests may not be available everywhere.
Hey, it's Benson. I made Tomebound. I drafted this guide with AI, then checked every step against the app myself. Tomebound is a passion project, and most of my time goes into making the tool great. If you collect Magic cards, I'd love for you to give it a try.
