A side-by-side look at the Epa Envirofacts and Met No MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Epa Envirofacts for environment & nature work as a local process; choose Met No for environment & nature as a local process. You can also run both side by side in one mcpServers block.
facilities_by_zip, facilities_by_state, get_facility.Rows where the two servers differ are marked.
