Environment / auth

SIGNUPGENIUS_EMAIL
SignUpGenius login email (recommended). Pair with SIGNUPGENIUS_PASSWORD for session mode — works on free accounts. No SSO/2FA.
SIGNUPGENIUS_PASSWORD
secret
SignUpGenius password (recommended) — required iff SIGNUPGENIUS_EMAIL is set.
SIGNUPGENIUS_USER_KEY
secret
SignUpGenius Pro API key (Pro Tools > API Management). Required only for slot REPORTS — Pro subscription needed.
SIGNUPGENIUS_NAME
Friendly account name used in startup logs.
SIGNUPGENIUS_BASE_URL
Override the default JSON API base (v2/k for key mode, v3 for session mode).
SIGNUPGENIUS_LEGACY_BASE_URL
Session mode only: override the host for legacy /SUGboxAPI.cfm calls. Defaults to https://www.signupgenius.com.
SIGNUPGENIUS_LOGIN_URL
Session mode only: override the login-form host. Defaults to https://www.signupgenius.com.
SIGNUPGENIUS_DISABLE_FETCHPROXY
Set to 1 to skip the fetchproxy browser-extension fallback (missing creds become a hard error — useful in headless CI).
SIGNUPGENIUS_SESSION_CACHE
Set to false to disable the on-disk session cache and re-authenticate on every process start. Defaults to enabled.
SIGNUPGENIUS_SESSION_FILE
Absolute path for the session cache file. Defaults to $MCP_DATA_DIR/.signupgenius-mcp/session.json.
