## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_snap_participation (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_food_environment (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_agricultural_data (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 920 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 4, about 920 tokens to load them all
- tool set hash: 43ff5db89c54d0d5228c7903f41a6621
- badge: [![protogrid quality](https://protogrid.dev/badge/com.olyport/usda-food.svg)](https://protogrid.dev/servers/com.olyport/usda-food)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `get_agricultural_data`: Get USDA NASS QuickStats data on agricultural production by state.

    Returns crop values, production quantities, and farm statistics from the
    USDA National Agricultural Statistics Service. Useful for understanding
    local food production capacity in grant narratives.

    Args:
        state: Two-letter state abbreviation (e.g. 'WA', 'IA').
        commodity: Agricultural commodity to query (e.g. 'CORN', 'SOYBEANS', 'WHEAT',
                   'CATTLE', 'MILK'). Omit to get a broad survey of crops.
        year: Year for data (e.g. 2022). Omit to get the most recent available data.
    
- `get_food_environment`: Get county-level food access risk profiles using Census ACS data.

    Constructs food access risk profiles by combining vehicle access (B25044),
    poverty status (B17001), and SNAP participation (B22001). Limited vehicle
    access combined with high poverty indicates food desert risk. Useful for
    identifying areas with barriers to food access in grant applications.

    Args:
        state: Two-letter state abbreviation (e.g. 'WA', 'MS') or 2-digit FIPS code.
        county_fips: Three-digit county FIPS code (e.g. '033' for King County, WA).
                     Omit to get all counties in the state.
    
- `get_food_insecurity_indicators`: Get food-related economic indicators as proxies for food insecurity by county.

    Combines SNAP participation rate (B22001), poverty rate (B17001), and
    median household income (B19013) to build a food insecurity risk profile.
    Higher SNAP rates, higher poverty, and lower income correlate with greater
    food insecurity. Useful for grant narratives demonstrating community need.

    Args:
        state: Two-letter state abbreviation (e.g. 'WA', 'MS') or 2-digit FIPS code.
        county_fips: Three-digit county FIPS code (e.g. '033' for King County, WA).
                     Omit to get all counties in the state.
        year: ACS 5-year estimate year (default 2022). Data covers year-4 through year.
    
- `get_snap_participation`: Get SNAP/food stamp household participation by county using Census ACS Table B22001.

    Returns the number and percentage of households receiving vs not receiving
    SNAP/food stamp benefits, broken down by county. Essential for understanding
    food assistance utilization in grant target areas.

    Args:
        state: Two-letter state abbreviation (e.g. 'WA', 'MS') or 2-digit FIPS code.
        county_fips: Three-digit county FIPS code (e.g. '033' for King County, WA).
                     Omit to get all counties in the state.
        year: ACS 5-year estimate year (default 2022). Data covers year-4 through year.
