What the publisher says

From the Epa repository's README, as published. We do not edit it. Read it on GitHub

@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. 9 Tools • 2 Resources

Overview

EPA environmental data across five federal programs — facility compliance (ECHO), toxic chemical releases (TRI), Superfund cleanup sites, drinking water systems (SDWIS), and environmental-justice screening (EJScreen) — plus real-time air quality via AirNow. Search facilities by location or compliance status, pull inspection and enforcement history, track toxic releases across a region, and screen a point for environmental-justice risk from any MCP client. Runs as a stdio process or a local Streamable HTTP server.
