# Grammarly MCP Server

> Use this tool when you need to automate content optimization and ensure AI-generated text appears human-like, solving problems of AI detection and plagiarism by iteratively rewriting text based on Grammarly scores and Claude suggestions. It takes in text inputs and outputs rewritten content that meets target thresholds for humanized content. Ideal for use cases where high-quality, undetectable AI-generated content is required, such as content creation and copywriting.
