## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `county_profile`

- 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
FEMA open-data profile of one county by 5-digit FIPS: NFIP paid claims summary, disaster declarations since 2000, FEMA inspections of owner applicants (Individuals and Households Program), NFIP Community Status Book and CRS classes. A value the source does not give is returned as "not in source", never 0.
```

### `flood_damage_by_water_depth`

- 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
Median damage ratio (FEMA actual cash value of the damage / actual cash value of the building) on NFIP paid claims 2015-2024, by interior water depth band and single-family one-floor segment. With building_value_usd, returns ratio x value: the median ratio of the band, not an estimate for this home.
```

### `nfip_claims_by_county`

- 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
NFIP paid building claims for one county, 2015-2024 and 2020-2024. Give a 5-digit FIPS code, or a county name and its state. A county absent from the table (it keeps counties with at least 100 paid claims) gets the state row, and the answer says so. These are amounts paid by NFIP, not repair cost.
```

### `nfip_claims_by_state`

- 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
NFIP paid building claims for one US state or DC, 2020-2024 (FEMA OpenFEMA, NFIP Redacted Claims v3): number of paid claims, quartiles and median of the amount paid, dominant flood event and its share. These are amounts paid by NFIP, not repair cost.
```

## Only reads (1)

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

### `list_sources`

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

Description, as the server wrote it:

```untrusted-server-text
Lists every source file this server reads, with publisher, dataset page, terms, as-of and retrieval dates, and the RestoreWorth page that publishes it.
```
