Environment

Name	Required	Notes
SIGNUPGENIUS_EMAIL	No	SignUpGenius login email (recommended). Pair with SIGNUPGENIUS_PASSWORD for session mode — works on free accounts. No SSO/2FA.
SIGNUPGENIUS_PASSWORD	No	SignUpGenius password (recommended) — required iff SIGNUPGENIUS_EMAIL is set. Secret.
SIGNUPGENIUS_USER_KEY	No	SignUpGenius Pro API key (Pro Tools > API Management). Required only for slot REPORTS — Pro subscription needed. Secret.
SIGNUPGENIUS_NAME	No	Friendly account name used in startup logs.
SIGNUPGENIUS_BASE_URL	No	Override the default JSON API base (v2/k for key mode, v3 for session mode).
SIGNUPGENIUS_LEGACY_BASE_URL	No	Session mode only: override the host for legacy /SUGboxAPI.cfm calls. Defaults to https://www.signupgenius.com.
SIGNUPGENIUS_LOGIN_URL	No	Session mode only: override the login-form host. Defaults to https://www.signupgenius.com.
SIGNUPGENIUS_DISABLE_FETCHPROXY	No	Set to 1 to skip the fetchproxy browser-extension fallback (missing creds become a hard error — useful in headless CI).
SIGNUPGENIUS_SESSION_CACHE	No	Set to false to disable the on-disk session cache and re-authenticate on every process start. Defaults to enabled.
SIGNUPGENIUS_SESSION_FILE	No	Absolute path for the session cache file. Defaults to $MCP_DATA_DIR/.signupgenius-mcp/session.json.
FETCHPROXY_WS_PORT	No	Localhost port of the fetchproxy concentrator the ContextMint Bridge extension connects to (default 37149). Every MCP on one machine shares it, so move it for all of them or not at all.
FETCHPROXY_WS_HOST	No	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	No	Absolute path where the fetchproxy long-term identity keypair is stored (default ~/.fetchproxy/identity/).
