generate-contentLABSCO SUMMARY
The discovery tools are what make the generation usable.
Generating on-brand copy needs IDs the model has no way to guess, so listing style guides, brand voices and audiences — with descriptions attached — is what lets it choose an appropriate tone instead of asking you for a UUID. apply-style is the quieter win: text you or the model already wrote gets conformed to the brand rules without regenerating it from scratch.
What it is
A prototype server for the Jasper AI API. What separates it from asking a model directly is that generation is anchored to your account's configuration: a style guide ID, a brand voice tone ID and an audience ID, all fetched from Jasper and passed into the request. It can also take text you already have and conform it to a style guide.

Requirements
A Jasper API key, set as JASPER_API_KEY. The quickest path in Cursor or Windsurf is npx -y against the repository; for Claude Desktop there is a .dxt extension you drag into the Extensions window and configure with your key. If npx misbehaves under nvm, clone it, pnpm install, pnpm run build, and point the config at dist/index.js with an absolute node path (package jasper-ai-mcp-prototype, version 1.0.0). It is labelled a prototype by the authors.
Setup effort
Add the configuration to your client
USE CASES
01
Writing copy that matches your brand rules
Pick the brand voice and audience from the list, then generate against them.
02
Bringing existing text in line with the style guide
Pass the draft through the styling tool rather than rewriting it.
03
Choosing the right tone for a specific reader
Read the audience descriptions and let the model match one to the brief.
04
Finding out what your Jasper account is configured with
List the style guides, voices and audiences available to you.
