AI assistants and lesgooo.fun — FAQ
Short answers about privacy, safety and limits when you plan through an assistant.
The basics
lesgooo.fun is a free group planner with no login: one link per plan, where the group compares available days and exact hours, votes on places, answers the RSVP, keeps a checklist and splits costs. AI assistants connect through an open MCP server and do the same things a person does in the app — for the person they help.
Frequently asked questions
Is it free?
Yes. The app and the MCP server are free, with fair-use limits that normal use never reaches.
What can an assistant see?
The same as anyone with the plan link: the title, event details, names, free days, exact availability windows, RSVPs, places, checklist and costs of that plan. Share plan links only with your group.
Can an assistant change other people’s answers?
An assistant should act only for the person using it and ask which name is theirs. The participant token helps prevent accidental cross-person edits within that conversation, but lesgooo has no account verification: anyone with the plan link can choose an existing name and edit that person's answers. Share the link only with your group.
How do others know an assistant answered?
A small grey bot icon appears beside participants who used an assistant to fill in the plan.
Will my assistant act without asking me?
A clear request authorizes that specific change. The assistant should ask first when your identity or an important detail is unclear. A suggestion alone does not authorize a new action, and free-time overlap does not confirm an Event.
Do my friends need an assistant or an account?
No. Everyone else just opens the link in a browser. No account, no app install.
Which assistants work?
Any that support remote MCP servers — for example Claude, ChatGPT (developer mode), Claude Code, Cursor and VS Code. See the connect guide.
Can an assistant delete things?
An assistant can remove an expense, payment, checklist item or place added by the person it acts for, after that person confirms. It cannot delete the plan or entries added by others.
How can I get help?
Email lesgooofun@gmail.com with questions about the app or its assistant connection.
What if I hit a limit?
You will get a message explaining the limit. Read the plan before retrying to see which parts were saved. The website is a useful fallback, but its writes and paid lookups also have cost limits.
Where is the technical summary?
https://lesgooo.fun/llms.txt (short) and https://lesgooo.fun/llms-full.txt (full docs). The server is listed in the official MCP Registry as fun.lesgooo/lesgooo.
Can the assistant tell the difference between a free day and free hours?
Yes. All-day dates and exact free-time windows are stored separately. The assistant can compare actual overlapping windows in a specified timezone. Include your timezone with hours; availability alone does not set the agreed Event or RSVP.
Prefer to plan yourself?
The app works the same without an assistant — one link, no signup.
