Have any AI agent write a book from one line.
Proseify is an MCP server that hands your agent a header-verified library of 81 classics, the craft of each genre, and a complete pipeline — plan, outline, draft, measure, polish. Your AI writes the prose. Proseify supplies the literature.
No LLM API key required. Your client's own model does the writing — there is no token bill from us.

Why "header-verified" matters
A corpus built from guessed book IDs is a corpus full of mislabelled files. Proseify reads each record from the file itself and audits all 81 entries against their own headers — so when your agent asks for a gothic exemplar, it gets the book it asked for.

The pipeline
Six tools, one book.
Your agent calls these in order. Each one returns craft and structure — never prose, so your token bill stays yours.
1
plan_book
A plain-language idea becomes genre, blend, chapter count and arc.
2
get_style_references
Real exemplars from the corpus, filtered by voice and tense.
3
create_outline
Beats placed at act markers — hook, midpoint shift, climax, resolution.
4
draft_chapter
A directive per chapter, with a length rule and genre craft notes.
5
evaluate_book
Structure and pacing scored against the target, with a KEEP verdict.
6
polish_book
Strips the scaffolding and hands back a finished file.

Before you connect.
Which AI clients work with Proseify?
Claude Code, Claude Desktop, Cursor, Windsurf, VS Code Copilot, OpenAI Codex, Gemini CLI and the ChatGPT desktop app — anything that speaks MCP. Connect over Streamable HTTP with your key, or run Proseify locally from the repository.
Do I need an LLM API key as well?
No. Proseify supplies the corpus, the craft, the outline and the evaluation. Your AI client writes with its own model, so there is no separate API key and no inference bill from us.
How long until my key works?
Keys propagate to the server on a 60-second cycle. If your very first call is refused, wait a moment and retry — it will be live.
Can I cancel?
Yes, any time. Your key stops working at the end of the billing period.
What exactly is in the corpus?
81 public-domain books across 11 genres, 2,568 indexed chapters. Every record is read from the file's own Gutenberg header and audited, so the metadata is trustworthy rather than assumed.
