Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

compare

compare_svi

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).

county

get_county_svi

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).

most

get_most_vulnerable

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).

tract

get_tract_svi

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).

CDC Social Vulnerability Index — questions

Answers built from our own checks of this server.

What can CDC Social Vulnerability Index do?

It exposes 4 tools, read directly from the server on our last check. Among them: compare_svi, get_county_svi, get_most_vulnerable, get_tract_svi. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is CDC Social Vulnerability Index working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 546 ms. The bar chart above shows every period we have measured.

How do I connect CDC Social Vulnerability Index?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does CDC Social Vulnerability Index need an API key?

No. CDC Social Vulnerability Index completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is CDC Social Vulnerability Index?

It answers our handshake in 546 ms on average, which is faster than 19% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
