Content Optimizer

This is a free, open source alternative to paid SEO tools like Surfer SEO and Clearscope. It exposes six MCP tools that score content against SERP competitors across seven categories: keyword usage, word count, heading structure, readability, entity coverage, content depth, and internal structure. The score_content tool gives you a 0-100 grade with per-category breakdowns, while analyze_keyword pulls data from top 10 ranking pages to set benchmarks. You also get readability scoring via Flesch-Kincaid, heading hierarchy analysis, and a find_missing_topics tool that shows what competitors cover that you don't. Useful when you're writing or editing SEO content and want data-driven recommendations without a monthly subscription.
