Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (4)
🟢get_county_svi(state, county_fips, year)
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_tract_svi(state, county_fips, year, limit)
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).

}🟢get_most_vulnerable(state, theme, limit)
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).

}⚪compare_svi(fips_codes, year)
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).
