Claude Cowork & Plugin

Run every StorytellerOS studio from inside a Claude conversation — drafting titles, generating story bibles, capturing tasks, logging finance, managing your calendar, all without leaving the chat.

What you'll need

  • An active StorytellerOS account.
  • Claude Cowork (claude.ai/code) or Claude Code in the terminal.
  • ~5 minutes to add the connector + install the plugin.

What is this?

StorytellerOS ships a Claude plugin that lets you drive the entire workspace from inside a conversation. Ask Claude to draft chapter 4 in your cozy pen-name's voice, build out a full story bible from an uploaded manuscript, log a $400 editing expense to the right title, start a writing timer, schedule a release-day event, or pull a quarter's finance summary — all without leaving Claude.

Under the hood the plugin talks to a hosted MCP endpoint at https://storytelleros.com/api/mcp that mirrors the public/api/v1/* REST surface. Everything Claude does, you can do from the dashboard — and everything you do from the dashboard, Claude can do too.

Two pieces, intentionally split

  1. The connector lives in Claude itself (Cowork or Claude Code). It holds your credentials and authenticates with our OAuth endpoint.
  2. The plugin is installed from the marketplace and adds the conversational skills + slash commands that make Claude fluent in StorytellerOS-specific workflows.

We split them on purpose. When a plugin bundles a connector, Cowork locks the credential fields — which would block you from pasting your own. Keeping the connector separate keeps your credentials editable and revocable.

What's included

  • A shared MCP tool catalog (stos_*) — operations across titles, chapters, scenes, characters, locations, lore, events, tasks, calendars, time-tracking, finance, sales, marketing, and settings. See the tools reference.
  • 28 skills — markdown chat guides that make Claude fluent in specific workflows (getting started, drafting chapters, building bibles, logging finance, driving WordPress, the social hand-off, …). See the skills reference.
  • 7 slash commands — quick-fire commands like /stos-task and /stos-bible. See the slash command reference.

Using ChatGPT instead

ChatGPT uses the same hosted tool catalog and 28 guided skills, with its own OAuth connection. Follow the ChatGPT installation guide; do not reuse Claude's MCP URL. Existing Claude connections keep working. The seven slash commands documented here are Claude-specific; ChatGPT users can describe those tasks in ordinary language.

Install Reader Radius alongside STOS

StorytellerOS handles writing, knowledge, finance, calendar, sales, and marketing. For the complete conversational workflow, install both the STOS and Reader Radius plugins and authenticate both MCP connections. Reader Radius handles social campaigns, posting, and scheduling.

When you ask Claude to post, schedule, or run a campaign, the StorytellerOS social-handoff skill uses the selected STOS pen name and title context, then calls Reader Radius tools. This is intentional and also applies in ChatGPT. Enable both products in the conversation. See the two-product setup guide.

No story-bible shortcuts

When Claude generates a story bible (characters, locations, events, lore), it saves each entry as its own POST — never batched. For large manuscripts that means 50+ individual stos_characters_create calls. Slower than a bulk upload, but every field arrives intact instead of getting truncated mid-batch. This is deliberate.
