## Findings

No check matched anything in these tool definitions.


## Only reads (4)

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

### `get_earnings_event`

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

Description, as the server wrote it:

```untrusted-server-text
Earnings event: 8-K acceptance timestamp, as-reported figures, and the derived realized
price reaction. `fiscal_period` is FY or Q1..Q4.
```

### `get_filing_metadata`

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

Description, as the server wrote it:

```untrusted-server-text
SEC filings for `ticker` available on `as_of_date`, newest first, with amendment linkage.
```

### `get_fundamentals`

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

Description, as the server wrote it:

```untrusted-server-text
Point-in-time fundamentals for `ticker` as known on `as_of_date` (YYYY-MM-DD).
Returns each available metric's value for the fiscal period with source + knowledge time +
lineage under `metrics`. Any requested metric with no value appears under `unavailable` with
`{reason, available_alternatives, docs_url}` instead of being silently dropped — e.g. asking a
bank/broker/insurer for `revenue` explains that financials report an as-reported revenue FAMILY
and lists the populated members (net_interest_income, noninterest_income, total_net_revenue,
premiums_earned, net_investment_income, total_revenue). Check `unavailable` before concluding a
figure does not exist.
```

### `get_index_constituents`

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

Description, as the server wrote it:

```untrusted-server-text
S&P 500 (or other index) constituents as understood on `as_of_date` (YYYY-MM-DD),
survivorship-free. Point-in-time, with lineage.
```
