An MCP server designed to audit webpage document outlines. It ensures structural integrity by checking for proper H1-H6 nesting, verifies the presence of target keywords in headings, and calculates semantic density to measure information richness across different heading levels. Use check_hierarchy to detect skipped levels or multiple H1s, verify_keywords to ensure SEO compliance, and calculate_semantic_density to assess content variety.

Check if this list of headings has any hierarchy errors: [{'level': 'h1', 'text': 'Title'}, {'level': 'h3', 'text': 'Subtitle'}]

The hierarchy is invalid because an H3 follows an H1, skipping the H2 level.

Are the keywords 'SEO' and 'HTML' present in my headings?

Yes, both 'SEO' and 'HTML' were found in your heading structure.

Calculate the semantic density for these headings: [{'level': 'h1', 'text': 'Main Title'}, {'level': 'h2', 'text': 'Section 1'}]

The density score for h1 is 1.0 and for h2 is 1.0.

Use the `check_hierarchy` tool by providing an array of objects containing the level and text of your headings. Tools available: `your_tool_name`.
