Deckofcards

pipeworx-io/mcp-deckofcards

Wraps the free Deck of Cards API so you can shuffle decks, draw cards, and manage piles programmatically from Claude. It's hosted via Pipeworx's gateway, which means zero setup and no API keys to manage. Useful if you're prototyping card game logic, building poker hand evaluators, or teaching probability concepts with live shuffles and draws. The ask_pipeworx interface lets you request operations in plain English rather than calling tools directly. Part of a larger gateway that connects to 600+ data sources, but this endpoint isolates just the card deck functionality if that's all you need.

Parameters* required

categoriesstring

Comma or space separated subset of econ|fed|fda|sec|court, or "all" (default). E.g. "econ,fed" or "fda".

hoursnumber

Look-ahead window in hours from now. Default 48. Capped at 720 (30 days) — econ/fed releases are dated weeks apart, so a short window is often empty; widen rather than assume nothing is scheduled.

Parameters* required

assetstring

btc (default) | eth | sol | xrp | bnb. Coverage differs by venue: polymarket and polymarket-us carry btc/eth/sol/xrp, Kalshi carries btc/eth/bnb.

bucket_ppnumber

Price-bucket width in percentage points: 5 | 10 (default) | 20 | 25 | 50. Must divide 100, so the last bucket is never narrower than the rest.

horizonstring

15m (default). 5m | 1h | 1d are accepted but only 15m is collected today, so another value returns coverage.windows_total 0 rather than an error.

minutenumber

Minutes elapsed since window open, 0-based. Omit for the full grid; pass 5 for the "five minutes in" row only, which is also the cheapest query.

side_conventionstring

"favorite" (default) folds each window onto whichever side was the favorite — the frame published claims about early favorites use. "yes" keeps the venue own YES/Up side.

venuestring

polymarket | polymarket-us | kalshi | all (default polymarket). "all" returns one grid per venue, never a merged one.

updown_venue_compareThe same 15-minute crypto "up or down" window priced on polymarket.com, Polymarket US and Kalshi, side by side, with whether each pair is actually the same contract.

Parameters* required

assetstring

horizonstring

15m (default and the only value offered).

windowstring

"current" (default), "next", "previous", or the window START as an ISO-8601 timestamp on a 15-minute boundary, e.g. 2026-10-27T14:15:00Z. An unaligned timestamp is refused, not rounded.

Parameters* required

assetstring

btc (default) | eth | sol | xrp | bnb. The archive holds btc/eth on all three venues, sol/xrp on polymarket.com and Polymarket US, bnb on Kalshi only (no pair).

Look-back in days, 1-90 (default 30). The archive starts 2026-09-22 (polymarket.com, Kalshi) and 2026-10-07 (Polymarket US, btc), so a longer span is capped by what is held; coverage is reported pe...
