This MCP server provides specialized tools to ensure markdown documents are structurally sound for LLM consumption. It performs character-level analysis to validate heading hierarchy, prevent excessive list nesting, ensure marker consistency, and verify code block parity. Use analyze_markdown_structure for a full audit, check_heading_hierarchy to prevent skipped heading levels, or validate_list_integrity to check nesting depth and marker usage.

validate_list_integrity

See how to talk to your AI agent using Markdown Structure Compliance Validator.

Check if this markdown is valid: # Title\n## Subtitle\n- Item 1\n - Item 2\n - Item 3\n - Item 4

The document has a violation: the list nesting depth exceeds the maximum limit of 3 levels.

Is the heading hierarchy correct in: # Header 1\n### Header 3

No, the heading hierarchy is invalid because H2 was skipped.

Validate the list markers in: - Item 1\n* Item 2

The list contains marker mismatches because hyphens and asterisks are used at the same level.

The compliance score is a percentage representing the ratio of valid structural elements to the total number of structural elements detected in your markdown.
