## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 75/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 641 tokens (~128/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

Get all CDC PLACES health measures for a county.

    Returns up to 36 measures including health outcomes (diabetes, obesity,
    heart disease, etc.), health behaviors (smoking, binge drinking), preventive
    services (checkups, screenings), and health status indicators.

    Args:
        county_fips: 5-digit county FIPS code (e.g. '53033' for King County, WA).
                     Must be a string, not an integer.
        year: Optional release year to filter by. Omit for the most recent data.

Input parameters:

- `county_fips` (string, required)
- `year`

### `get_tract_measures` (~133 tokens)

Get all CDC PLACES health measures for a census tract.

    services, and health status indicators. Tract-level data uses small area
    estimation and may have wider confidence intervals than county data.

    Args:
        tract_fips: 11-digit census tract FIPS code (e.g. '53033005300').
                    Must be a string, not an integer.
        year: Optional release year to filter by. Omit for the most recent data.

Input parameters:

- `tract_fips` (string, required)
- `year`

Output parameters:

- `result` (string)

### `get_measure_by_state` (~135 tokens)

Get one CDC PLACES measure for all counties in a state.

    Useful for comparing a specific health metric (e.g. DIABETES, OBESITY)
    across all counties within a state. Returns the most recent data year.

    Args:
        state_abbr: Two-letter state abbreviation (e.g. 'WA', 'CA').
        measure_id: PLACES measure ID (e.g. 'DIABETES', 'OBESITY', 'BPHIGH').
                    Use search_measures to find valid IDs.

Input parameters:

- `state_abbr` (string, required)

Output parameters:

- `result` (string)

### `search_measures` (~95 tokens)

Search available CDC PLACES measures by name or category.

    Returns matching measure IDs, names, and categories. Use this to find
    the correct measure_id for other tools.

    Categories: Health Outcomes, Health Behaviors, Prevention, Health Status.

    Args:
        keyword: Search term (e.g. 'diabetes', 'smoking', 'prevention', 'heart').

Input parameters:

- `keyword` (string, required)

Output parameters:

- `result` (string)

### `compare_counties` (~138 tokens)

Compare specific CDC PLACES measures across multiple counties.

    Returns a side-by-side comparison of selected health measures for the
    given counties. Useful for benchmarking one county against peers.

    Args:
        fips_list: List of 5-digit county FIPS codes (e.g. ['53033', '53053', '06037']).
                   Maximum 10 counties per request.
        measures: List of PLACES measure IDs to compare (e.g. ['DIABETES', 'OBESITY']).
                  Maximum 10 measures per request.
