CDC Social Vulnerability Index

CDC Social Vulnerability Index is an MCP server that provides county and tract SVI scores and theme breakdowns to agents via streamable HTTP.

About

CDC Social Vulnerability Index is an Olyport-hosted MCP server that exposes CDC SVI scores and thematic factor breakdowns for US counties and census tracts through streamable HTTP. developers working on disaster preparedness apps, mutual-aid networks, grant-backed community programs, or benefits navigation tools can connect it so agents describe audiences using federally standardized vulnerability dimensions rather than anecdotal targeting. It shines in the Idea phase when you define who is underserved and why, and in Validate when funders or partners expect SVI-backed rationale in one-pagers. This is an integration for public analytics agents, not a CRM: you still handle outreach, consent, and local partnerships. Server version 1.1.0 aligns with the 2025-12-11 MCP server schema; intermediate users can add the remote alongside other Olyport CDC endpoints for composite community research.

What it does

Layer CDC Social Vulnerability Index scores and theme breakdowns to prioritize underserved counties and tracts for equity-focused products.

Who is it for?

civic, disaster, and social-impact developers who must prioritize vulnerable geographies with CDC SVI evidence.

Skip if: Commercial products that need individual-level poverty scores or non-US vulnerability frameworks SVI does not represent.

What you get

With the MCP registered, your agent can embed SVI-backed audience segmentation into research docs and validation briefs.

SVI-ranked geography lists for audience and partnership planning
Theme breakdown summaries for positioning and grant sections
Agent-ready vulnerability context for map and outreach feature specs

get_county_svi3 params

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_svi4 params

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_vulnerable3 params

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_svi2 params

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).
