FICTURN

Stories you enter.

FICTURN is a chat-native library of short, finished fiction designed to be read directly inside ChatGPT through an MCP-powered inline reader.

Current library

The Safehouse Rule — romantic suspense, ~6 min
Room 713 — uncanny hotel horror, ~5 min
The Last Reply — near-future digital-twin thriller, ~8 min

The story prose is fixed and versioned in the repository. FICTURN does not generate or rewrite the core story text on the fly.

Reader

The inline reader supports:

story library and selection
progress indicator
Previous / Continue navigation
return to Library
mobile reading inside ChatGPT
no login
no database
no payment or advertising

MCP tools

browse_stories — show the current FICTURN catalog
start_story — open one story at part 1
next_fragment — retrieve the requested next fixed fragment

All tools are read-only.

Architecture

TypeScript
Cloudflare Worker
stateless MCP endpoint at /mcp
story content versioned in src/story.ts
inline reader widget in src/widget.ts
public website and policy pages served by the same Worker

Public routes:

/ — product page
/privacy — privacy policy
/terms — terms of use
/support — support
/.well-known/openai-apps-challenge — OpenAI domain-verification token when configured

Deploy

Cloudflare Workers can import this GitHub repository directly. The default deploy command is:

Terminal

npx wrangler deploy

The production MCP URL is:

https://ficturn.thomas-judes.workers.dev/mcp

For OpenAI plugin-domain verification, set the Worker environment variable OPENAI_APPS_CHALLENGE to the exact token generated by the OpenAI submission portal. The Worker then serves that token as plain text at:

text

/.well-known/openai-apps-challenge

Development

Terminal

npm install
npm run typecheck
npm run dev

Deploy manually with:

Terminal

npm run deploy
