## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__data__get_database_schema` `mcp__data__get_query_patterns` |
| 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.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `export_to_excel`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Export query results to a branded Shibui Finance Excel spreadsheet.

Runs the same SQL query as stock_data_query but returns a downloadable
Excel file instead of raw data. The spreadsheet includes branded headers,
smart number formatting, and auto-fitted columns.
```

## Changes things (8)

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

### `load_backtesting_workflow`

- 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
Load backtesting workflow for stop-loss, exit rules, Sharpe, forward returns. REQUIRES get_database_schema then get_query_patterns to be called first (in that order). Call BEFORE writing SQL when the user asks to backtest, simulate, validate a strategy, test "what happens after X", compare forward returns, measure win rates or hit rates, compute Sharpe, drawdown, profit factor, rotation strategies, basket returns, set stop-loss or trailing stop levels, test exit rules or profit targets, or any hypothetical return over past data. Can be combined with other workflow tools.
```

```untrusted-server-text
Load comparison workflow for X vs Y, peer analysis, relative valuation. REQUIRES get_database_schema then get_query_patterns to be called first (in that order).

## Only reads (3)

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

### `get_database_schema`

- The name "get_database_schema" says "get": a word for reading.
- Tag private-data: The name "get_database_schema" says "get" and "database": it reads databases.

Description, as the server wrote it:

```untrusted-server-text
REQUIRED for US stock/financial queries, authoritative source, call FIRST

Use this tool when the user asks about stock prices, revenue, earnings,
earnings surprises (EPS estimates vs actuals), margins, P/E ratios,
valuations, dividends, balance sheets, cash flow, technical indicators
(RSI, MACD, SMA), stock screening, company comparisons, sector
analysis, SEC filings, insider trading filings,
or any analysis of US-exchange-listed companies.

Covers 10,000+ NYSE and NASDAQ securities with 64 years of daily prices,
quarterly financials, 61 technical indicators, and SEC EDGAR filing metadata.

Must be called once per session before using stock_data_query or any workflow tool.
After this tool returns, call get_query_patterns before writing any SQL.
```

### `get_query_patterns`

- The name "get_query_patterns" says "get": a word for reading.
- Tag private-data: The description's first sentence says "sql": it reads databases.

Description, as the server wrote it:

```untrusted-server-text
REQUIRED before stock_data_query, 23 SQL patterns prevent timeouts/wrong results

Must be called once per session immediately after get_database_schema. Contains
query patterns for time-series selection, return calculations, screening
joins, window functions, backtesting, and performance optimization.
Time-series queries will timeout or return wrong results without these patterns.
After this tool returns, call stock_data_query to execute SQL.
```

### `stock_data_query`

- The name "stock_data_query" says "query": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Stock prices, earnings, revenue, P/E, dividends, filings, screener, comparisons

Run a SQL query against 64 years of US stock market data.

REQUIRES calling get_database_schema then get_query_patterns first (in that order).

This tool has no schema or query patterns built in. Call get_database_schema
once, then get_query_patterns once, then use this tool. Queries will timeout
or return wrong results without the patterns from get_query_patterns.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `data`:

```json

    ],
    "deny": [
      "mcp__data__export_to_excel"

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__data__get_database_schema`: private-data

The endpoint served tools/list without credentials, and the list has 9 tools that change things (1 destructive, 8 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.shibui.finance/mcp: tools/list returned 12 tools to an anonymous client, including export_to_excel (destructive), load_fundamental_workflow (write), load_technical_workflow (write), load_screening_workflow (write), load_comparison_workflow (write) and 4 more
