Étincel MCP server
by AIStoryHub · official
Your AI can check your writing for machine-sounding habits and learn to draft in your own voice.
Étincel is a writing helper that looks at your text and points out the patterns that make it read like a machine wrote it, such as paragraphs that are all the same length or phrases like "leverage" and "seamless". It also lets you train your AI to write more like you, using samples of your own writing. It is handy for anyone who writes memos, blog posts, docs, or emails and wants them to sound human.
What is an MCP server? The 30-second version
On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to a service. This one connects your AI to Étincel, a writing checker and voice trainer. Once it is connected, your AI can scan your drafts for AI tells and draft new text in a style you have taught it.
What this MCP server does
You ask your AI to check a piece of writing, or to draft something new. The AI passes your text to this helper. The helper runs a fixed set of rules over the words and measures things like sentence length and paragraph shape. It hands back a score, a list of specific findings with locations, and a note about what is working well. If you have trained a voice, it can also feed that style to the AI before it drafts.

What it gives back to you
You get a plain report in the chat: a tier like green, orange, or red, a score, and a list of findings with severity and a short explanation of each one. It also shows a strengths signal, such as how specific the writing is and how much sentence rhythm varies. For style training, it confirms the voice was saved and you can use it by name afterward.
Before you start
What you need
- The Claude desktop app or another MCP client
- Node.js installed if you run it with npx
- Your own writing samples if you want to train a voice
Good to know
It can permanently delete a trained voice, and forking a public style makes a network call to etincel.ai, but the audit itself never changes your text.
