Use My Next Book from your AI app

Connect Claude, ChatGPT or Claude Code to your shelves. Then just ask — “what's on my To Be Read that's under 300 pages?” — or tell it to add a book, and it happens in the app.

Claude

Tap the button, then Add. Claude sends you here to sign in and choose what it's allowed to do.

Add to Claude

Needs a paid Claude plan (Pro or higher). Button not working? In Claude, open Settings → Connectors → Add custom connector, name it My Next Book and paste this URL:

https://mynextbookapp.com/mcp

On iPhone, add it on claude.ai in a browser once — it then works in the Claude app too.

ChatGPT

In ChatGPT's settings, find Developer mode (under Apps or Connectors, then Advanced) and turn it on.
Choose Create, name it My Next Book, paste the URL below and pick OAuth.
Sign in here when ChatGPT asks.

https://mynextbookapp.com/mcp

Needs ChatGPT Plus or higher.

Claude Code

Run this once in a terminal, then use /mcp in Claude Code to sign in:

claude mcp add --transport http mynextbook https://mynextbookapp.com/mcp

Things to try

“What's on my To Be Read shelf? Pick me something funny.”
“Add Piranesi to my Currently Reading shelf.”
“I finished The Left Hand of Darkness — move it to Read and give it four and a half stars.”
“What are people in my groups reading that I'm not?”
“Recommend Station Eleven to my book club group.”

What it can do

The connection acts as you, with the access you have in the app. When you connect, you choose read-only or read-and-change.

Read

get_profile — who the connection acts as, shelf counts, groups
list_my_books — your shelves, with your notes (paged)
get_book — one book: description, authors, ratings
list_member_books — a group-mate's shelves and the notes they share with the group
search_libraries — search your and your group-mates' shelves
search_titles — search the book catalog
get_trending — what readers or one of your groups are adding
list_groups, get_group, get_group_recommendations — your groups and their recommendations

Change (only if you allow it)

add_book, update_book, move_book, reorder_list, rate_book — your own books
archive_book, restore_book, delete_book — take books off your shelves or bring them back
recommend_to_group, respond_to_recommendation, remove_recommendation — group recommendations
create_group, create_group_invite, leave_group — your groups

It can't join a group for you, rename or delete a group, change your household or touch your account. Connected apps get up to 500 actions, 100 changes and 100 catalog searches a day, resetting at midnight UTC.

The app acts as you, with the same access you have in My Next Book — it sees your notes and who recommended your books, and it only sees other people's shelves through groups you share. It can't join groups for you, change your household or touch your account. You can make it read-only when you connect, and disconnect it any time from Connected apps.
