Packages and local setup

The published npm package is signupgenius-mcp, version 2.1.8. Its declared MCP transport is stdio.

The package declares SIGNUPGENIUS_EMAIL: SignUpGenius login email (recommended). Pair with SIGNUPGENIUS_PASSWORD for session mode — works on free accounts. No SSO/2FA.; SIGNUPGENIUS_PASSWORD: SignUpGenius password (recommended) — required iff SIGNUPGENIUS_EMAIL is set.; SIGNUPGENIUS_USER_KEY: 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..
