Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →

  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Unverified: 1 category

A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

Tool Tokens
epa_get_ejscreen ~307

Get EJScreen environmental-justice indicators for a point and surrounding buffer. Returns the 13 EJScreen environmental indicators (PM2.5, ozone, diesel particulate, NO2, lead paint, traffic proximity, Superfund/RMP/hazardous-waste/wastewater proximity, underground storage tanks, drinking-water non-compliance, and RSEI toxic air releases) and 6 demographic indicators (people of color, low income, limited English, less than high school, under 5, over 64), each with national and state percentiles plus EJ Index values, along with the Demographic Index and Supplemental Demographic Index. Data is EJScreen v2.2 (2022) served via the community-maintained EJAM API (api.ejanalysis.com, Public Environmental Data Partners), which rehosts EJScreen after EPA discontinued public access in 2025 — not a live EPA endpoint. Provide latitude, longitude, and a buffer distance (default 1 mile, max 15 miles). Points outside US coverage return a coverage note instead of indicators.

epa_get_tri_releases ~180

Query Toxic Release Inventory annual chemical release data for a specific facility. Returns per-chemical release records with chemical name, total release quantity, and reporting year. TRI data lags ~18 months — the most recent available year is typically 2 years prior to the current calendar year. Obtain facility_id (TRI facility ID) from epa_search_facilities. Use epa_search_tri_releases to identify top emitters across a region.

Returns facility name, EPA Registry ID, coordinates, county FIPS code, per-program registration flags, inspection counts, penalty totals, and TRI release totals. Registry IDs returned here feed epa_get_facility and epa_get_tri_releases. Supports proximity search via latitude + longitude + radius_miles. At least one geographic filter (zip_code, state, city, or a complete latitude+longitude+radius_miles triple) is required — unscoped searches time out.
