## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `screen_assets`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Screen the normalized mkts asset snapshot with bounded price, return, volume, market-cap, type, and sector filters. Returns at most 25 records.
```

## Only reads (14)

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

### `compare_assets`

- The name "compare_assets" says "compare": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Compare 2 to 10 market symbols using the same normalized mkts snapshot. Returns requested and resolved symbols plus normalized asset records with provenance metadata.
```

### `get_archive_series`

- The name "get_archive_series" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Get what mkts recorded for up to 100 symbols on every day in a date range, from the immutable point-in-time archive. This is the shape a portfolio backtest actually needs — N symbols by M days in one call, where get_asset_series would take one call per holding and get_assets_as_of one per day. Each row carries observedAt and isRevision, so a later restatement stays visible rather than replacing the original. Days the market was shut are absent, not zero-filled. Limits: 366 days, and symbols multiplied by days must not exceed 10000.
```

### `get_asset_intraday`

- The name "get_asset_intraday" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Get every price observation mkts made of one symbol inside a time window, rather than just the daily close. Use for intraday movement, timing questions, or checking what a price was doing during a session; use get_asset_series instead for daily closes over months. Cadence is not uniform across the archive — roughly 15 minutes since March 2026 and much sparser before — so the response reports observedIntervalMinutes for the window you asked for, and you should read it before treating the data as fixed bars. interval buckets the result, keeping the last observation in each bucket. Maximum window 92 days; intraday reaches back further on paid tiers.
```

### `get_asset_profile`

- The name "get_asset_profile" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Resolve a symbol from the mkts multi-asset snapshot. Returns identity, asset type, price, change, market cap, volume, and snapshot timestamp when available.
```

### `get_asset_quote`

- The name "get_asset_quote" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Get a current quote for a stock, ETF, cryptocurrency, commodity, or forex pair. Returns price fields, market state when available, an observation timestamp, and upstream source.
```

### `get_asset_series`

- The name "get_asset_series" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Get what mkts recorded for one symbol on every day in a date range, from the immutable point-in-time archive. Use this for backtesting rather than calling get_assets_as_of once per day — a 90-day study is one call here and 90 there. Distinct from get_price_history, which fetches OHLCV live from upstream providers: this returns what was observed at the time, with observedAt and isRevision per row, so a later restatement is visible instead of silently replacing the original. Days the market was shut are absent rather than zero-filled. Maximum range 366 days.
```

### `get_assets_as_of`

- The name "get_assets_as_of" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Get what mkts recorded about one or more symbols on a specific past date, from the immutable point-in-time archive. Pass a single symbol or up to 100. Use for backtesting, reconstructing a past decision, or checking whether a figure was later revised — not for current prices, which get_assets_bulk serves. Revisions recorded after the requested date are excluded, so results never leak hindsight into a historical decision. Check isExactDate on each result: false means the market was closed and the most recent earlier observation was returned instead.
```

### `get_assets_bulk`

- The name "get_assets_bulk" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Get current data for an explicit list of up to 100 symbols in a single call. Use this instead of calling get_asset_quote repeatedly — a watchlist fetched one symbol at a time exhausts the rate limit for no benefit. Returns the resolved assets plus unresolvedSymbols naming anything not tracked, so a short list is never silently short.
```

### `get_filings`

- The name "get_filings" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Get recent filing records for a US stock or ETF. Returns filing date, type, title, and EDGAR link; optionally filter by filing type.
```

### `get_fundamentals`

- The name "get_fundamentals" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Get annual or quarterly financial-statement time series for a stock or ETF. Modules can return all statements or a smaller financials, balance-sheet, or cash-flow payload.
```

### `get_macro_snapshot`

- The name "get_macro_snapshot" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Get the current mkts macro dashboard, including major equity proxies, crypto, commodities, the US dollar, volatility, and the US 10-year yield.
```

### `get_market_snapshot`

- The name "get_market_snapshot" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Get the current global cryptocurrency market totals, volume, dominance, active asset counts, and the underlying snapshot timestamp.
```

### `get_news`

- The name "get_news" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Get recent market news from the configured source feeds. Filter by an asset symbol or by markets, crypto, commodities, or forex category. Returns source and publication links.
```

### `get_price_history`

- The name "get_price_history" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

Get bounded daily price history for a symbol. Stocks and ETFs include OHLCV when available; cryptocurrency history may contain close and volume only.
```
