## 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 |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__portfolio-terminal__analyze_ticker` `mcp__portfolio-terminal__compare` `mcp__portfolio-terminal__dividend_calendar` `mcp__portfolio-terminal__earnings_calendar` `mcp__portfolio-terminal__fund_fees` `mcp__portfolio-terminal__tax_loss_harvest` |

## Changes things (8)

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

### `dividend_calendar`

- 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
US stocks and ETFs (of the 420 Portfolio Terminal covers) going ex-dividend in a month or a date range: ex-dividend date, pay date, dividend per share, yield, frequency, and whether the date is confirmed by the company or estimated from its payment rhythm. Buy before the ex-date to receive the dividend. Filter by one ticker with `symbol`.
```

### `earnings_calendar`

- 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
US companies (of the 390 Portfolio Terminal covers) reporting earnings in a month or a date range: the day, before the open or after the close, EPS and revenue estimates, whether the date is confirmed or estimated, and once out, the result against the consensus and how many recent quarters beat it. Filter by one ticker with `symbol`.
```

### `etf_holdings`

- 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.

Description, as the server wrote it:

```untrusted-server-text
An ETF's or index fund's holdings from the issuer's full file (or its latest SEC N-PORT report for funds outside the catalog): the largest lines with their weights, the sector mix, and how concentrated it is (weight of the top 10, how many names make up half the fund, effective number of holdings). Share classes of one fund (VFIAX → VOO) resolve to its file.
```

### `etf_overlap`

- 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.

Description, as the server wrote it:

```untrusted-server-text
How much of two ETFs is the same money: overlap by weight (the sum, over companies both hold, of the smaller of the two weights), how many companies they share, what share of each fund sits in names the other also holds, and the largest shared holdings. Full issuer files, matched on ISIN. Use it for "VOO vs QQQ overlap", "is IVV the same as VOO".
```

### `fund_fees`

- 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
Computes, on the funds and amounts the user gives, what each fund's expense ratio takes a year (amount × expense ratio), the total and the weighted ratio, with the expense ratios of Portfolio Terminal's fees view (the fund's latest annual report as Yahoo Finance lists it). A fact, not a verdict: no other fund is suggested. A line that is not a fund, or whose ratio is not published, is named. Nothing is stored. Use it for "how much do my ETFs cost me a year".
```

### `tax_loss_harvest`

- 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
Computes, on the lots the user gives (ticker, shares, price, date, account and its type), the losses a sale before December 31 would realize and what they offset, with the engine of Portfolio Terminal's "Before December 31" panel. US resident: FIFO lots per account, short vs long term, this year's realized gains, the year netted as Schedule D nets it (the $3,000 off ordinary income, the carryforward), and the wash-sale rule across every account, IRA and 401(k) included: losses it took this year, windows still open, and the first day the same security can be bought back without one (IRS Publication 550). French resident: weighted average cost across accounts at ECB rates, PEA and crypto left out, and the flat tax those losses erase against this year's net gains (CGI art. 150-0 D, 200 A). Funds on the same index are flagged, never judged "substantially identical". Current prices are fetched unless given in `prices`. Nothing is stored. Use it for "how much tax can my losses save before December 31", "would this be a wash sale".
```

### `who_holds`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Which of the 54 tracked US ETFs hold a US-listed stock (weight and rank, from each issuer's full holdings file, matched on ISIN), and which famous investors hold it in their latest SEC Form 13F (share of their reported portfolio, rank, quarter). Offline data: fast, no market call. Use it for "which ETFs hold PLTR", "does Buffett own Apple".
```

### `withholding_check`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Computes, on the dividends the user gives (a year of dividends, gross, by payer: a ticker such as "NESN.SW" or a country code), the tax each payer's country keeps at source, the treaty rate, and what was withheld above it over 12 months, which only that country refunds on a claim; for a French resident, also the treaty part France credits on form 2047. Same engine as Portfolio Terminal's Income and Pro tabs: statutory rates as of 2026, a US dividend at 15% (W-8BEN on file), European-listed funds paying no withholding. Countries outside its table are named, never guessed. Nothing is stored. Use it for "how much Swiss tax do I lose on Nestlé dividends", "which of my dividends are over-withheld".
```

## Only reads (2)

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

### `analyze_ticker`

- The name "analyze_ticker" says "analyze": 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
Dated key facts and a plain-English chart read for one ticker Portfolio Terminal covers (390 US stocks, 30 ETFs, 17 cryptocurrencies and 4 commodity futures): price and one-year change, 52-week range, distance from the 200-day average, 30-day volatility with a risk rating, P/E and dividend yield, all-time high and "lowest since", ten years against the S&P 500 (SPY), support and resistance levels, which tracked ETFs and famous investors (13F) hold it, and related research. Use it for "how is NVDA doing", "is TSLA near its high", "what does the AAPL chart say".
```

### `compare`

- The name "compare" 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
Five-year head-to-head of two covered stocks or ETFs from weekly closes adjusted for dividends and splits: total and annualized return, 1-, 3- and 5-year returns, volatility, worst drawdown and worst week, correlation, what $10,000 became, plus each one's dividend yield, beta and (for funds) fee. Use it for "SCHD vs VIG", "NVDA vs AMD".
```
