lesgooo is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.
create_planCreates a new saved lesgooo group plan with the user as its first participant. Use when the user wants to start planning something new. Returns the shareable plan links and the participant's private credentials (participant_id, participant_token) needed for later changes. Title aget_planReads a saved plan: title, Event details, participants with their all-day and exact-time availability and RSVP answers, best dates and shared free-time windows, suggested places with votes, and the currency. Use when the user shares a plan link or asks about a plan's current statjoin_planAdds the user to a saved plan under their name, or selects the existing participant with that name, and returns that person's private credentials. Use when the user wants to take part in an existing plan or act as a specific participant in it. With existing credentials it renamesset_availabilityChanges one participant's availability: all-day dates and/or exact free-time windows (ISO start and end with offset, plus the IANA time_zone). mode=add merges, remove subtracts, replace overwrites. Use when the user says which days or hours they are or are no longer free. It doesset_rsvpRecords whether the participant is coming to the plan's Event: yes, no, or clear to remove the answer. For a repeating event it answers one occurrence (the next one by default, or occurrence_date). Use when the user says they are or are not attending.add_placeSuggests a place for the group to vote on (Where). By default it searches Google Places and returns up to five candidates without saving (status needs_selection); calling it again with the chosen google_place_id saves the place with its official details, map link and photo. sourcvote_placeUp-votes, down-votes or clears the participant's vote on a suggested place. Use when the user expresses a preference for or against a place in the plan.get_checklistReads the plan's shared checklist: open and done items with their item_id. Use when the user asks what still needs doing or what is on the list.add_checklist_itemAdds one item to the plan's shared checklist: one task, ingredient or thing to bring per call. Use when the user wants something added to the to-do or packing list.check_itemMarks a checklist item done (done=true) or open again (done=false). Use when the user says a task is finished or needs reopening.update_eventUpdates the shared Event details everyone sees: title, date and time (local time, no time zone; no start_time means all day), location and description. Omitted fields stay unchanged; an empty string clears a field. Use when the user sets or changes the agreed event details or renget_expensesReads the plan's shared costs: recorded expenses and payments, each participant's balance and the suggested transfers to settle up, in the plan's currency. Use when the user asks who paid what or who owes whom.add_expenseRecords a shared expense split equally: description, amount, currency, who paid (defaults to the participant) and who shares it (defaults to everyone). It records the cost only and moves no money. Use when the user reports something they or someone in the group paid for.record_paymentRecords that the participant has already paid someone back (settling up); the amount defaults to what they owe that person. It records a completed payment only and moves no money. Use when the user says the money was actually sent.remove_entryDeletes an expense, payment, checklist item or place that this participant added; entries added by others cannot be removed. Use when the user asks to delete a specific entry, for example to correct a mistake.widget_writeApp-only transport for explicit interactions with shared web components. Reuses the web write gateway, validation and budgets. Requires the selected participant token for saved-plan edits.widget_select_participantApp-only identity picker. Bind the name explicitly selected in the shared web UI. Does not change schedule data.widget_lookupApp-only Places search/details and link previews. The backend retains feature flags, monthly provider counters and timeouts. Never calls a paid API from the browser.open_plannerOpens the interactive lesgooo planner (When, Where, Event, Checklist, Splitwise) in the conversation, optionally on a saved plan and module and as a previously selected participant. Without a plan it shows an unsaved local draft. Opening saves nothing. Use when the user wants to find_plan_mentionsResolve an explicitly supplied lesgooo saved-plan link or exact ID for the desktop mention picker. Empty or general searches return no results; never enumerate plans.open_preferencesOpen local widget preferences. Defaults and recent history stay on this device; does not change a shared plan.read_plugin_settingsRead the plugin settings layout. There are no account settings; the action opens device-local preferences.update_plugin_settingsNo primitive account settings are available. An empty update is a no-op; device preferences are changed in the widget.https://lesgooo.fun/mcpNot in Muse's Connectors list yet, but Muse can still use it.
