### `compare_svi`

- The name "compare_svi" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare SVI data across multiple counties.

    Returns side-by-side SVI percentile rankings and key indicators for
    the specified counties. Useful for comparing vulnerability across
    service areas or peer counties.

    Args:
        fips_codes: Comma-separated 5-digit county FIPS codes (e.g. '53033,53053,53061').
        year: SVI data year (default 2022, currently only 2022 available).
    
```

### `get_county_svi`

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

Description, as the server wrote it:

```untrusted-server-text
Get CDC Social Vulnerability Index data for counties in a state.

    Returns overall SVI percentile ranking and all four theme breakdowns
    (socioeconomic status, household composition/disability, minority
    status/language, housing type/transportation) plus key indicator
    estimates for each county.

    SVI values range 0-1 (percentile ranking); higher = more vulnerable.

    Args:
        state: Two-letter US state abbreviation (e.g. 'WA', 'CA').
        county_fips: Optional 5-digit county FIPS code to get a single county.
        year: SVI data year (default 2022, currently only 2022 available).
    
```

### `get_most_vulnerable`

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

Description, as the server wrote it:

```untrusted-server-text
Get the most vulnerable counties in a state ranked by SVI score.

    Returns counties sorted by highest SVI percentile ranking for the
    specified theme. Useful for identifying priority areas for grants
    and community health interventions.

    Args:
        state: Two-letter US state abbreviation (e.g. 'WA', 'CA').
        theme: SVI theme to rank by. Options: 'overall', 'socioeconomic',
               'household' (composition/disability), 'minority' (status/language),
               'housing' (type/transportation). Default is 'overall'.
        limit: Number of counties to return (default 20, max 100).
    
```

### `get_tract_svi`

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

Description, as the server wrote it:

```untrusted-server-text
Get tract-level CDC Social Vulnerability Index data within a county.

    Returns overall SVI and all four theme percentile rankings for each
    census tract in the specified county. Useful for identifying
    sub-county areas of high vulnerability.

    Args:
        state: Two-letter US state abbreviation (e.g. 'WA', 'CA').
        county_fips: 5-digit county FIPS code (e.g. '53033' for King County, WA).
        year: SVI data year (default 2022, currently only 2022 available).
        limit: Maximum number of tracts to return (default 50, max 500).
    
```
