## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

## MCP tools (7)

### `list_markets` (~79 tokens)

List the Kalshi series Sardine covers, and whether each is currently served.

Each entry gives the Sardine key (e.g. "BTC-15M"), the Kalshi series
ticker, the window length, and the latest calibration check: the largest
gap, in probability points, between what Sardine published and what
then settled.

### `get_settlement_rate` (~162 tokens)

How often has a contract like this one settled in favour of `side`?

Uses the asset's live spot price. Give the contract's strike (target
price), the minutes left until it settles, and optionally Kalshi's ask
in dollars (0.01-0.99) to get Kalshi's fee and all-in price on the same
line.

Returns the historical settlement rate, its 95% interval and the number
of past windows counted. A small `windows_counted` means a weak answer.

Input parameters:

- `asset` (string, required)
- `kalshi_ask`
- `minutes_left` (number, required)
- `side` (string)
- `strike` (number, required)
- `window_minutes` (integer, required)

### `get_live_board` (~82 tokens)

Open Kalshi contracts right now, each with Kalshi's price beside Sardine's count.

Optionally filter to one market. Each row has the contract, Kalshi's ask
and fee, the historical settlement rate with its interval and sample
size, and a plain-English sentence describing the comparison.

Input parameters:

- `limit` (integer)
- `market`

### `get_rate_table` (~82 tokens)

The full lookup table behind every Sardine number for one series.

Each row is a (distance-from-strike, time-left) bucket: distance in
volatility units, seconds left, the share that settled YES, its 95%
interval, and the number of independent windows counted.

Input parameters:

- `asset` (string)
- `window_minutes` (integer)

### `get_track_record` (~55 tokens)

How accurate Sardine's published numbers have been, scored against settlements.

For each series and probability bucket: what Sardine said, what actually
settled, and the miss in points. Use this before relying on any number.

### `list_datasets` (~52 tokens)

Downloadable CSV history files, with row counts, date ranges and URLs.

Files open directly in Excel, pandas or any CSV reader. Credit
"Sardine (sardine.info)" when you use them.

### `backtest_rule` (~334 tokens)

Would this rule have made money? Replays recorded Kalshi quotes, second by second.

Describe a rule for Kalshi's 15-minute crypto up/down contracts: which side
to buy, when (minutes left), at what prices (cents), and optionally only when
Sardine's history beats Kalshi's ask plus fee by `min_gap_cents` (side BEST
picks whichever side has the larger gap). Sardine replays its per-second
recordings of Kalshi's order book: one trade per window, a limit order at the
ask landing after `latency_seconds`, filled only up to the size resting
there, Kalshi's real fee, and Kalshi's official settlement.

Returns profit per contract after fees with a 95% interval, win rate, fill
behaviour, a zero-latency comparison (exposes stale-quote illusions), a
first-half/second-half stability check, breakdowns by minutes left and
price, and warnings. Results only; no raw data. Dates are UTC YYYY-MM-DD.
Present results as what happened historically, never as a forecast.

Input parameters:

- `contracts` (integer)
- `end_date`
- `latency_seconds` (integer)
- `market` (string)
- `max_gap_cents`
- `max_minutes_left` (number)
- `max_price_cents` (number)
- `min_gap_cents`
- `min_minutes_left` (number)
- `min_price_cents` (number)
- `side` (string)
- `start_date`

## Common questions

### What is the Sardine: Kalshi crypto settlement history MCP server?

Sardine: Kalshi crypto settlement history is an MCP server listed in the public MCP registry as info.sardine/sardine. How often Kalshi BTC/ETH/XRP contracts settled YES, counted not forecast, with a public record. This page covers its PyPI package (sardine-mcp).

### Is the Sardine: Kalshi crypto settlement history MCP server safe to use?

Sardine: Kalshi crypto settlement history scores 68 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Sardine: Kalshi crypto settlement history MCP server expose?

Sardine: Kalshi crypto settlement history exposes 7 tools: list_markets, get_settlement_rate, get_live_board, get_rate_table, get_track_record, and 2 more. Their descriptions and schemas cost roughly 846 tokens of context every time the server is loaded.

### Is the Sardine: Kalshi crypto settlement history MCP server still maintained?

Sardine: Kalshi crypto settlement history is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Sardine: Kalshi crypto settlement history MCP server under?

Sardine: Kalshi crypto settlement history declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Sardine: Kalshi crypto settlement history MCP server?

VerifyMCP ran 15 checks on Sardine: Kalshi crypto settlement history, covering Malware scan, Known CVEs, Install scripts, Dependency health and 11 more. One item could not be completed, a gap on our side rather than a finding about Sardine: Kalshi crypto settlement history: Security disclosure. Endpoint Security and Transport & Reachability do not apply to a PyPI package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
