How to automate Jasper

API and webhooks

Jasper has a developer portal with APIs, including an image API. Check the developer portal for webhook support. One concrete idea: call the API from your CMS workflow to draft product descriptions in your brand voice, then queue them for review.

MCP server

Jasper hosts an MCP server at mcp.jasper.ai with OAuth 2.0 or API key headers, and a local option via a desktop extension or an NPM package. It exposes nine tools: brand voices, audiences, style guides, products and knowledge search, agent execution, on-brand content generation and file upload. The IQ access is read only. One concrete idea: let your own AI assistant pull your brand voice and audience before it drafts an email.

Native integrations

Jasper has a browser extension and third-party integrations. One concrete idea: use the extension to draft and tighten copy directly inside your CMS or email editor.
