## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `submit_backtest`

- The name "submit_backtest" says "submit": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Submits a strategy for backtesting against historical OHLCV data. Returns immediately with an id and status — call get_backtest_result to fetch the outcome once it finishes. Testing the same strategy against many assets? Use submit_backtest_batch instead — one call per asset here adds up fast. Optionally accepts confirmationSources to only count a candidate Entry/Exit as a real trade once corroborated by a submit_confirmation_source result (multi-timeframe or cross-asset confirmation) — see the confirmationSources argument and submit_confirmation_source's own description.
```

### `submit_backtest_batch`

- The name "submit_backtest_batch" says "submit": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Submits ONE strategy against MANY asset pairs in a single call — the same backtest you'd get from calling submit_backtest once per asset, without needing dozens of round trips. Returns immediately with a batchId (pass it to get_backtest_batch_results to fetch every asset's outcome, paginated) plus the per-asset id/status assigned right away. Best-effort: one bad asset pair (unknown, or its date range outside coverage) shows up with an error in that item only — every other asset in the batch is unaffected. Optionally accepts confirmationSources, applied identically to every asset in the batch — see submit_backtest's own confirmationSources argument for the full semantics.
```

### `submit_confirmation_source`

- The name "submit_confirmation_source" says "submit": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Runs a strategy against historical data purely to produce a signal timeline used to confirm OTHER backtests — not a backtest itself. Walks the same candles and evaluates the same DSL as submit_backtest, but never simulates a position: no trade, no PnL, no WinRate/drawdown, none of that applies here, because this strategy is never meant to be traded on its own. Returns immediately with an id and status — call get_confirmation_source to check completion, then pass that id as a confirmationSources sourceId in submit_backtest (e.g. only count an XRP entry once a BTC-neutral confirmation source agrees). Costs the same capacity as a regular backtest of the same size — the compute is identical, it just skips trade simulation.
```

## Only reads (6)

Looks things up and changes nothing. Claude Code: allow.

### `get_backtest_batch_results`

- The name "get_backtest_batch_results" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetches every asset's outcome from a submit_backtest_batch call, paginated. By default (waitForCompletion: true) polls internally until every item in the batch is done — a cheap check, not one that pages through everything — so one call returns the finished page. Each item has the same aggregate metrics and recency fields (recentTradeCount/recentAvgPnlR/recentOutcomes) get_backtest_result returns for a single backtest, plus assetPair/status/error, so the single-result and batch-result shapes never drift apart. totalCount/completedCount/failedCount/pendingCount come back on every page, not just the last, so you can tell the batch is done from a single pageSize=1 call.
```

### `get_backtest_result`

- The name "get_backtest_result" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetches a submitted backtest by id. By default (waitForCompletion: true) polls internally until it finishes, so one call returns one final answer — no need to poll from the caller's side. Only aggregate metrics are returned here, no trade-by-trade detail — call get_backtest_trades for that (paginated, sortable). Fetching many results from the same submit_backtest_batch call? Use get_backtest_batch_results instead.
```

### `get_backtest_trades`

- The name "get_backtest_trades" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetches the closed-trade list for a completed backtest, paginated and sortable — the trade-by-trade detail get_backtest_result deliberately omits. Only closed trades ever appear; a position still open when the backtest's date range ends isn't represented here or anywhere else. Example: sortBy="exitTime", sortDirection="desc", pageSize=5 for the most recently closed trades.
```

### `get_confirmation_source`

- The name "get_confirmation_source" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetches a submitted confirmation source by id. By default (waitForCompletion: true) polls internally until it finishes, so one call returns one final answer. No trade-outcome fields here at all (no PnlR/WinRate/...) — a confirmation source never opens a position. Once Completed, its id can be used as a confirmationSources sourceId in submit_backtest; its raw signal timeline is available separately via get_confirmation_source_signals.
```

### `get_confirmation_source_signals`

- The name "get_confirmation_source_signals" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetches a completed confirmation source's raw signal timeline, paginated — the actual data a backtest's confirmationSources requirement is checked against. Can easily run into the thousands for a frequent condition over a long range (every candle-condition match is a row, not just closed trades), which is why this is paginated from the start. Debugging/inspection only — you do NOT need this tool to make confirmationSources work, and should not fetch these rows to reconstruct the gating yourself. To actually gate a backtest by this source, pass its id directly as sourceId in submit_backtest's own confirmationSources array; the backend applies the backward-only state check against this exact timeline automatically, including the higher-timeframe-to-lower-timeframe alignment. Reimplementing that alignment by hand from this raw data is unnecessary and easy to get wrong (e.g. failing to correctly persist a higher-timeframe state across every lower-timeframe candle until the next higher-timeframe close). Use this tool only to sanity-check a source's signal density or diagnose an unexpectedly low ConfirmedSignalsCount after the fact.
```

### `list_available_assets`

- The name "list_available_assets" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Lists every asset pair with real historical data, each with its supported timeframes and the date range actually available. Optional to call — submit_backtest already returns a clear error (with the real available range) when an asset or date range doesn't have data, so this is for up-front exploration or for recovering from an "unknown asset" error, not a required step before every submit_backtest.
```
