Write your book by chatting in Cursor.
Add BookWriter as an MCP server in Cursor and finish a real book without leaving your editor. You steer, the AI drafts, and every word you write is kept verbatim.
How to connect & set up
Cursor connects as a remote MCP server and signs in over OAuth — just like Claude. Add the Server URL, approve the BookWriter sign-in, and you’re writing.
Your Server URL
https://www.bookwriter.vip/api/mcp/v1Like ChatGPT and Claude, Cursor signs in over OAuth — add this URL and Cursor walks you through the BookWriter sign-in, no token to copy. (If an older Cursor build asks for a token instead, generate one on your connection page.) Cursor is also the one client that can reach a localhost Server URL.
- 1In Cursor, open Settings → MCP → Add new MCP server (or add the entry below to ~/.cursor/mcp.json) and paste the Server URL.
- 2Cursor detects that BookWriter uses OAuth and prompts you to sign in — approve it and sign in as your BookWriter account. Same one-click sign-in as Claude; no token to paste.
- 3Enable bookwriter in the MCP list.
- 4Ask Cursor to “Start a new book” to begin.
~/.cursor/mcp.json
{
"mcpServers": {
"bookwriter": {
"url": "https://www.bookwriter.vip/api/mcp/v1"
}
}
}Just the URL — Cursor handles the BookWriter sign-in over OAuth. (Older Cursor builds may instead want a Bearer token in a headers field; if so, grab one on your connection page.)
The write-a-book loop
Set up the book, write a seed paragraph, hand it off, sharpen, accept — then repeat. Your words are never overwritten.
- 1
Set up the book
Tell Cursor your premise and length. create_book spins up a real project — title, word target, chapter plan — not a blank prompt box.
- 2
Write a seed paragraph
Type a paragraph or a few lines to open the chapter. Those words are your seed, kept exactly as you wrote them.
- 3
Hand it off
handoff lets the engine finish the chapter in your voice, built around your words — your sentences are kept verbatim, never overwritten.
- 4
Sharpen, then accept
sharpen nudges the draft lighter or stronger until it reads right. accept_chapter locks it in and you repeat for the next chapter.
