Get the SignUpGenius profile of the authenticated user (name, email, member ID, subscription level). Useful as a first call to confirm credentials. Key mode hits /v2/k/user/profile; session mode hits /v3/member/profile.

Resolves the credential the way real tools do, then makes one authenticated request to api.signupgenius.com. Reports which source supplied the credential, whether api.signupgenius.com accepted it, the round-trip time, and a plain-English hint distinguishing 'no credential' from 'credential rejected' from 'a api.signupgenius.com-side problem'. Read-only; never returns the credential itself. Call this when a real tool fails and you want to know which hop broke.

List groups created by the authenticated user. Returns groupid, title, and member count for each group.

List members of a SignUpGenius group (basic info: name, email, memberid).

Get detailed info for a group member (address, phone, email) when the member has provided it via a sign-up.

Add a member to a SignUpGenius group by email address. First/last name are optional. Writes data — confirm with the user before invoking.

List sign-ups created by the authenticated user. In session mode this returns the full list (active + expired) — filter on enddate client-side if you need only active.

Alias of signupgenius_list_created_active in session mode (v3 returns active + expired together). Filter on enddate client-side.

List ALL sign-ups created by the authenticated user (active and expired).

List sign-ups the user has been invited to.

List sign-ups the user has personally signed up for.

Session mode only. Returns the same sign-up listing the SignUpGenius wizard sees (via /SUGboxAPI.cfm?go=t.getMySignups). Use when you want fuller data than signupgenius_list_created_* provides.

Full report for a sign-up: every slot plus the participant who claimed it (with custom-question answers when present). Requires SIGNUPGENIUS_USER_KEY (Pro subscription) — session mode is not supported for reports — AND only covers sheets the key-holder created. For slot dates, times and availability on ANY sign-up (including sheets the user did not create) prefer signupgenius_list_slots, which needs no auth.

Report for a sign-up restricted to slots that have already been filled. Requires SIGNUPGENIUS_USER_KEY (Pro subscription) — session mode is not supported for reports — AND only covers sheets the key-holder created. For slot dates, times and availability on ANY sign-up (including sheets the user did not create) prefer signupgenius_list_slots, which needs no auth.

Report for a sign-up restricted to slots that are still open/empty. Requires SIGNUPGENIUS_USER_KEY (Pro subscription) — session mode is not supported for reports — AND only covers sheets the key-holder created. For slot dates, times and availability on ANY sign-up (including sheets the user did not create) prefer signupgenius_list_slots, which needs no auth.

Look up a SignUpGenius sign-up by its public URL or slug (e.g. https://www.signupgenius.com/go/<urlid>-<signupid>-<vanity>). Returns the real sheet metadata: title, description, organization, category, creator + contact email, timezone, created/modified dates, whether it is an RSVP or slot-based sheet, and which custom fields a participant must supply to sign up. Requires NO SignUpGenius auth and works for sheets the user did not create. Use signupgenius_list_slots for the actual dates/times and availability — this tool returns metadata only.

List every SLOT on a SignUpGenius sign-up — date, day of week, start/end time, title, location, capacity, how many spots are filled vs still available, and who has already signed up (with the quantity each entry consumes). Accepts a sign-up URL, slug, or numeric id. Requires NO auth and works for sheets the user did NOT create, which is exactly the case the Pro signupgenius_report_* tools cannot serve (they are key-only AND owner-scoped). This is the right tool for "what is still open?".

RSVP to a SignUpGenius sign-up (the Yes/No/Maybe-style sheets, including invitations from family/friends). WRITES DATA the organizer sees, so it asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call sends nothing and returns the preview (sheet, response, head counts, identity) and a confirmToken, and only a repeat call with the same arguments plus that token submits — show the preview to the user and get their approval first (MCP_CONFIRM_MODE). Refuses when the signed-in member already has a response on the sheet (it can only ADD a response, so a second one would double-count) — change an existing answer in the SignUpGenius web UI. Slot-based sign-ups (e.g. "claim the 3pm slot") are NOT handled here — use signupgenius_claim_slot for those.

Claim (sign up for) a slot on a slot-based SignUpGenius sheet. WRITES DATA the organizer sees, so it asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call writes nothing and returns the preview (sheet, slot, identity) and a confirmToken, and only a repeat call with the same arguments plus that token submits — show the preview to the user and get their approval first (MCP_CONFIRM_MODE). For Yes/No/Maybe headcount sheets use signupgenius_rsvp instead.

Withdraw (give up) a slot the user previously signed up for. WRITES DATA — this removes a real sign-up, so it asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call removes nothing and returns the preview (sheet, slot, whose entry) and a confirmToken, and only a repeat call with the same arguments plus that token withdraws — show the preview to the user and get their approval first (MCP_CONFIRM_MODE).
