Proseify is a hosted MCP (Model Context Protocol) server that turns Claude Code, Codex, Cursor, or any MCP client into a disciplined book-writing machine — grounded in real literature instead of generic model defaults.
Give it a one-line premise. It picks the right genre recipe, pulls model passages from a curated public-domain library, plans the outline, drafts chapter by chapter, and scores its own work. You get a manuscript you can actually edit, not 40 pages of "it was a dark and stormy night."

Most "AI writes a book" tools generate immediately. The output reads the same way regardless of what you asked for — the same sentence lengths, the same dialogue rhythm, the same endings.
Proseify flips the order:
The genre recipe is derived from the actual tradition — pacing beats, dialogue ratio, sentence-length profile, how endings are handled. The agent reads it before touching prose. That single ordering decision is the difference between a horror book that reads like the gothic tradition and a horror book that reads like ChatGPT.
| Tool | What it does |
|---|---|
list_genres | 11 genres, growing library of books (theatre, horror, romance, adventure, literary, and more) |
search_corpus | Full-text search across all chapters, with FTS5 syntax (quotes, AND/OR/NOT, wildcards) |
get_genre_recipe | Pacing beats, dialogue ratio, and stylistic anchors derived from the tradition |
get_style_references | Model passages from books matching a genre — the register you're aiming for |
plan_book | Full chapter-by-chapter outline from a one-line premise |
write_book | The one-shot flow: plan → draft → evaluate, all in one session |
evaluate_book | Scores a drafted book against genre benchmarks so weak chapters get revised |
…plus supporting tools for chapter retrieval and corpus metadata.

The anti-prose-slop skill gives the agent the writing workflow — genre
recipe first, corpus grounding, chapter discipline, and a per-chapter
anti-slop editing pass — instead of just raw tool access.
Tell the agent a premise:
"I want a gothic horror novel about a lighthouse keeper finding a body that shouldn't exist. 32 chapters. Budget 50,000 words."
The agent picks the right recipe, searches the corpus for register, plans, drafts, scores, and revises. You edit what it returns.
a growing library of books / 11 genres, drawn from Project Gutenberg and similar public-domain collections — all verified against their original headers, so there is no copyright ambiguity anywhere in the library. Commercial use of output built on it is safe.
A partial list: works from Austen, Stevenson, Hugo,conrad, Verne, the Brontës, Shelley, gothic masters, and more — selected, grouped by genre, and indexed for search.
Because the failure mode of AI-written prose isn't bad grammar — models are
word-perfect. It's sameness: "seemed to", "began to", stacked adverbs,
repeated sentence constructions, filter words, dialogue-as-exposition,
chapter openings that always start with weather. The skill that ships with
Proseify has a concrete per-chapter checklist against each of these, and
evaluate_book scores the result against genre norms so the agent can
self-revise rather than ship its first pass.
