Environment variables

Defined in the server's official registry manifest. Required secrets are shown as <YOUR_…> placeholders in the configs above.

MAH_WS_PORT — Override the fetchproxy WebSocket port (default 37149).
MAH_READ_ONLY — true refuses mah_reply_message sends (previews still work). Default false.
MAH_USERNAME — MyAtriumHealth username. Set with MAH_PASSWORD to enable bridge-less mode. Leave both empty to relay through your signed-in browser tab.
MAH_PASSWORD secret — Portal password. Both are required; setting only one falls back to the bridge (with a warning).
MAH_DOTENV — Path to a .env file read first; failing that ~/.myatriumhealth-mcp/.env, then ./.env. A real MAH_USERNAME / MAH_PASSWORD in the environment always wins.
MAH_DEVICE_FILE — Session state (0600), default ~/.myatriumhealth-mcp/device.json. Holds the live cookie jar as well as the device token — treat as a credential.
FETCHPROXY_WS_HOST — Bind interface for the fetchproxy concentrator, a literal IP only (default 127.0.0.1). Keep on loopback; it exists for hosted deployments that run each MCP in its own network namespace.
FETCHPROXY_IDENTITY_DIR — Absolute path where the fetchproxy long-term identity keypair is stored (default ~/.fetchproxy/identity/).
