Epa MCP Server

@cyanheads/epa-mcp-server Search and retrieve EPA environmental data: facility compliance (ECHO), toxic releases (TRI), Superfund sites, drinking water systems, environmental-justice screening (EJScreen), and real-time air quality (AirNow). STDIO or Streamable HTTP.

Overview

EPA environmental data across five federal programs — facility compliance (ECHO), toxic releases (TRI), Superfund sites, drinking water systems (SDWIS), and environmental-justice screening (EJScreen) — plus real-time AirNow air quality. Pull a facility's inspection and enforcement history, track toxic releases across a region, or screen any point for environmental-justice risk.

All resource data is also reachable via tools — use epa_echo_get_facility and epa_superfund_get_site for programmatic access in tool-only MCP clients.

Capability reference

epa_echo_search_facilities tool

• Provide ZIP code, state, city (prefix match, preferably with state), county (prefix match on the recorded name; needs state), 5-digit county_fips, or latitude + longitude + radius_miles (max 100 miles). facility_name (whole words in any order, no commas; also matches other names ECHO records for the facility) and naics (2–6 digits, prefix match) narrow a geographic search
• Up to 100 facilities per call (default 50); a larger limit, up to 5,000, returns 100 with a limitNotice. Page with offset and nextOffset; totalCount is the match before limit and offset
• Returns registryId for epa_echo_get_facility, triFacilityIds for epa_tri_get_facility_releases, county and fipsCode, coordinates, per-program flags, and five-year inspection and penalty totals. effectiveQuery echoes the filters as sent
• programs takes one of CAA, CWA, RCRA, TRI, or SDWA; has_violation keeps facilities in significant noncompliance; active_only keeps facilities with an active permit

epa_echo_get_facility tool

• registry_id is a Registry ID from epa_echo_search_facilities or a program ID ECHO resolves to one: a PWSID from epa_water_search_systems, a TRI facility ID, an NPDES permit, or a RCRA handler ID. The profile carries the resolved registryId
• Returns complianceStatus, the naics codes its programs record, a per-statute programCompliance summary, five years of enforcement actions with penalties (caseId feeds epa_echo_get_case), the latest TRI total with triReleasesTransfersYear, and triFacilityIds for epa_tri_get_facility_releases
• Two paged lists: inspections from the last five years, newest first (inspections_limit default and cap 100, inspections_offset; inspectionsTotal counts them all and inspectionsNextOffset continues), and drinkingWaterViolations for a public water system, newest compliance period first, each with contaminant, measured level, MCL, status, and enforcement actions (drinking_water_violations_limit default 50, cap 200, drinking_water_violations_offset; drinkingWaterViolationsTotal and drinkingWaterViolationsNextOffset). A larger limit returns the cap with a limitNotice, and truncated is true while either list has more
• If the status lookup fails, the profile returns without complianceStatus and a notice says so; an unknown ID fails as facility_not_found

epa_echo_search_violations tool

• Requires state or zip_code; up to 100 cases per call (default 50), and a larger limit up to 5,000 returns 100 with a limitNotice. Page with offset and nextOffset; effectiveQuery echoes the filters as sent
• program filters CAA, CWA, RCRA, SDWA, CERCLA, EPCRA, FIFRA, or TSCA, matching any law a case cites; case_type is civil, criminal, or all (default)
• date_filed_start / date_filed_end (YYYY-MM-DD, inclusive) bound the filing date. Only civil cases carry filing dates, so with a date all returns civil cases with a notice, and criminal is rejected
• Returns caseId, caseName, caseType, caseStatus, enforcementOutcome, leadAgency, the primary law (programsViolated) and primarySection, federal and state/local penalties, cost recovery, compliance action and SEP costs, and filed, settlement, and closed dates. Criminal cases omit status, outcome, state/local penalty, and cost fields
• Case rows name no facility: pass a civil caseId to epa_echo_get_case

epa_echo_get_case tool

• case_id is a civil case number: a caseId from epa_echo_search_violations (such as 03-2014-7010) or a formal action's caseId from epa_echo_get_facility. A criminal CR_ number fails as criminal_case before any request; an unknown number fails as case_not_found
• Returns the case's category code, enforcement type, status, lead agency, relief sought, outcome, court and DOJ docket numbers, summary, and penalty, cost-recovery, compliance-action, and SEP totals, plus lawsAndSections, defendants, pollutants, and milestones
• facilities lists the facilities the case names, one per Registry ID, with address, NAICS and SIC codes, and the program IDs the case links; pass a registryId to epa_echo_get_facility
• enforcementConclusions lists each order, consent decree, or other settlement with its facilities, dates, penalties and costs, complying actions, pollutant reductions, and Supplemental Environmental Projects
• The report is not paged: a case naming 115 facilities and 117 settlements returns about 120 KB across both response surfaces

epa_airnow_get_conditions tool

• Provide zip_code (5 digits, or a ZIP+4 read as its first five) or both latitude and longitude; mode is current (default) or forecast
• Current mode returns each pollutant's latest hourly NowCast AQI from the closest monitor within 50 miles; forecast mode returns each issued day with dateValid, actionDay, and discussion, and forecast_date (a real YYYY-MM-DD date) keeps one day
• Readings carry categoryName and categoryNumber (1 Good–6 Hazardous); attribution marks the data preliminary and unsuitable for regulatory or enforcement decisions
• Registered only when AIRNOW_API_KEY is set; responses cache for about one hour

epa_tri_get_facility_releases tool

• facility_id is the TRI facilityId from epa_tri_search_releases or epa_echo_get_facility triFacilityIds; optional year (1987–2030) and partial chemical_name
• Returns per-chemical on-site releases to air, water, land, and underground injection, their sum totalOnSiteReleasesInLbs, and the Form R Section 8.8 oneTimeReleaseInLbs, which the media quantities already include, newest reporting year first
• limit defaults to and is capped at 500 filings; a larger value up to 5,000 returns 500 with a limitNotice. Page with offset and nextOffset; truncated, shown, cap, and guidance mark a page with more
• Quantities are in pounds; dioxin records reported in grams are converted and carry reportedUnit: "grams"

epa_tri_search_releases tool

• Requires 2-letter state (any case); optional county (case-insensitive partial match on the bare name; a trailing County, Parish, Borough, City and Borough, Census Area, or Municipality is dropped), partial chemical_name, and year; newest reporting year first when year is omitted
• Up to 200 records per call (default 50); a larger limit up to 5,000 returns 200 with a limitNotice. Page with offset and nextOffset; effectiveQuery echoes the filters as sent. Records come in reporting-year order, not ranked by quantity
• Returns facilityId for epa_tri_get_facility_releases, registryId for epa_echo_get_facility, parentCompany, and the Form R Section 8.8 oneTimeReleaseInLbs; include_release_breakdown: true adds on-site releases to air, water, land, and underground injection plus totalOnSiteReleasesInLbs, at the cost of one more upstream request (up to ~20 seconds when EPA has not cached it)
• Dioxin records reported in grams are converted to pounds and
