The data behind the conversation
What Pokémon data
can your AI access?
Prices are just the start. Explore sales, supply, set values, and the conversations moving through the hobby—all through the Trading Card Data MCP server. Coverage and history vary by product and source.
Prices & activity
Raw card & sealed-product prices
Look up exact cards, finishes, languages, and sealed formats. Compare available TCGplayer, eBay, and Cardmarket marketplace estimates with their currencies and observation dates.
“What is this exact Gengar variant worth across marketplaces?”
Estimates and asking prices are not matched completed sales; source coverage varies.
Price history & market movers
Explore dated price changes, compare products, and screen cards by set, rarity, price, or supported market measures. Daily, weekly, and monthly briefs bring market activity together.
“Which cards in this set gained the most over 30 days?”
History length varies. Missing observations are not zero or a prediction.
Sales volume & order samples
Track estimated TCGplayer units and orders by calendar week alongside prices. Inspect available order samples as separate evidence.
“Add weekly sales volume to this price chart.”
Volume is estimated; samples are not the full market. Current partial weeks are labeled.
Store offers & price per pack
Compare recorded offers from tracked US and Canadian stores, or compare supported sealed products by price per pack.
“Which available products have the lowest price per pack?”
Store availability is as of the recorded crawl, not guaranteed live stock.
Graded cards & sets
Graded prices & price history
Compare available graders and grades, including PSA 10. Follow dated market estimates and available recorded-sale series for the exact card.
“How has this card’s PSA 10 price changed?”
Graded estimates and recorded sales remain separate. Coverage differs by grader and grade.
Graded population & growth
Inspect reported grade counts, gem-mint counts, and changes between dated population reports, including PSA 10.
“How much has this card’s PSA 10 population grown?”
Net reported population growth is not grading submission intake or complete circulating supply.
Set values & value concentration
Compare raw and PSA 10 set totals, pack benchmarks, and sealed-to-set ratios. Explore how much value sits in the top cards and which cards contributed to a basket’s change.
“Compare this set’s raw value with its booster box price.”
Priced subsets and raw/graded baskets can differ. Total value and fixed-basket performance are different measures.
Release-window comparisons
Compare supported sets at the same age before or after release, using available raw, graded, and price-per-pack observations.
“Compare these sets during their first 30 days after release.”
Only shared observed ages are compared. Preorder prices are distinguished from post-release prices.
Market context
Creator discussions & community sentiment
Find source-linked creator commentary and tracked YouTube, Reddit, and forum discussions. Explore bullish and bearish reasons around sets, cards, reprints, or grading.
“What are tracked creators saying about this set?”
Coverage is limited to tracked sources. Opinions are not verified causes or future-price evidence.
Release dates, restocks & news
Look up recorded English US set releases and rotation dates, dated retailer restock alerts, and indexed news about releases, reprints, grading, and competitive play.
“When did this set release, and what restocks were reported?”
Set debuts differ from product waves. Alerts do not establish inventory quantities or print runs.
Google search interest
Explore dated relative search interest for tracked sets, products, and market terms.
“How has search interest in this set changed?”
Each keyword has its own relative 0–100 scale; it is not search volume or a cross-keyword popularity ranking.
Tournament results & deck context
Look up recorded tournament entries, event dates, divisions, and available leading deck archetypes.
“Which deck archetypes led at this recorded event?”
Recorded standings are not spectators or complete all-age attendance; event coverage varies.
Put the data to work
Custom charts, market indexes, and personal research tools.
Combine supported series in custom charts, compare market indexes, and create personal indexes from supported assets. Private alert tools let you save conditions and check them when requested; they do not promise automatic push notifications. Predictive models are not included in the research membership.
A few things to know
Good questions.
What does this add to my AI assistant?
A dedicated connection to Trading Card Data’s price lookups, available history, market screens, and chart tools. Your assistant supplies the conversational interpretation; Trading Card Data supplies the data and research views.
Which cards and products are covered?
The current offering focuses on Pokémon: raw cards, graded cards, and sealed products. Availability differs by source, variant, grade, and date. A catalog listing does not guarantee usable price history.
Are the prices live? Is volume exact?
Prices are dated observations, not a live trading feed. Marketplace estimates differ from individual sales and active listings. Estimated sales volume is labeled, and partial periods should not be compared as full periods.
Is my AI subscription included?
No. The membership pays for Trading Card Data’s research service. Any subscription required by your assistant is separate.
How do charts affect my assistant’s usage?
Our widgets display charts and card images, reducing the need for your assistant to write display code or repeat results as long tables. This is designed to reduce unnecessary reply tokens; actual usage depends on your assistant, plan, and question.
How do I manage or cancel my membership?
Manage your monthly membership from your Trading Card Data account. Canceling stops future renewals; access continues through the paid period.
Do product links earn a commission?
Eligible product links may earn Trading Card Data a commission. Affiliate links are disclosed where they appear; commissions do not change research rankings.
