Connect Claude to your manuscript

Most “AI in your editor” stories end the same way: the AI starts writing the book. Calliope’s MCP access is the rare one that doesn’t. You can connect Claude to your manuscript — or Cursor, or any MCP client — and it will read every word, reason about your cast, tend your canon. It still cannot write a sentence of your prose. Not because you forgot to turn it off. Because there is no switch.

What MCP is, in plain words

MCP — the Model Context Protocol — is a standard way for an AI client to reach into an outside service and use it as a set of tools. Calliope speaks it. Our MCP service is live at mcp.writecalliope.ink, and it exposes your manuscript — chapters, structure, your Map of facts — as tools a client can call.

So when you connect Claude to your manuscript, you’re not pasting your novel into a chat window and hoping. Your agent points at Calliope, authenticates as you, and works against the real book: the same canon the web app holds, the same single source of truth. Whatever Claude reads is what’s actually on the page.

What a connected client can do

A client you’ve connected has the run of the manuscript for reading, and — with a subscription — a careful set of write powers that all stop short of the prose:

• Read anything — chapters, structure, synopses, your whole Map of characters and locations and facts. Ask Claude what you established three chapters ago and it can go and check.
• Write annotations — leave notes, todos, references, and research beside the prose.
• Write structure — create, rename, reorder, and re-status chapters and parts.
• Write the Map — create, edit, alias, and merge the facts that make up your canon.

This is real augmentation with teeth: an agent that can tidy your outline, reconcile your cast, and file what it finds — working the scaffolding around the book so you can stay on the book.

What it can never do

A connected client can never write or edit your chapter prose. There is no prose-write tool and no prose-write scope for it to call — by design, and forever. The model isn’t being asked nicely to stay out of the manuscript; the door was never built. When you connect Claude to your manuscript, the most it can do to a sentence is read it.

This is the augmentation promise made unbreakable. Everywhere else in Calliope, “the app never writes your prose” is a principle. Here it’s a property of the wire. The refusal holds even for the robots — and that is the strongest proof we can offer that the words stay yours.

Connecting and reading is free

Pointing a client at Calliope and reading your manuscript costs nothing. Connect Claude to your manuscript, let it read the whole thing, ask it about your canon — all free. We monetize being the grounding layer your agent trusts, not the act of reading your own book.

Write access — annotations, structure, the Map — comes with the MCP subscription: €12/month, or €99/year (about 31% off). The subscription also includes a €10/month Calliope-AI allowance that works across both the web app and your connected client, so the AI tools your agent runs over MCP draw on the same Calliope balance as everything else.

The shape of it

To connect Claude to your manuscript: you get a server URL, point your MCP client at it, authorise it as you, and start reading immediately for free. Subscribe when you want your agent to tend the canon as well as read it. Throughout, one line never moves — your agent can know your book completely and still never write a word of it.

That’s the whole bargain. A read-everything, edit-the-scaffolding, never-touch-the-prose agent for the novel you’re actually writing.
