mcp-markdown-tools

An MCP (Model Context Protocol) server that provides tools for working with Markdown content. Analyze, lint, format, and generate Markdown programmatically through any MCP-compatible client.

Tools

generate_toc

Generate a table of contents from markdown headings. Configure minimum/maximum heading depth and choose between ordered or unordered list output.

lint_markdown

Check markdown for common issues including broken link syntax, heading hierarchy violations, trailing whitespace, missing image alt text, inconsistent list markers, and excessive blank lines.

format_markdown

Format and prettify markdown content. Normalizes heading styles (converts setext to ATX), fixes spacing around headings and blocks, aligns table columns, and wraps long lines at configurable width.

markdown_stats

Compute detailed statistics from markdown content: word count, character count, estimated reading time, headings by level, link count, image count, code block count with language distribution, list items, blockquotes, and paragraph count.

generate_table

Generate formatted markdown tables from JSON data. Supports column selection, custom header labels, and per-column alignment (left, center, right).
