Overview

What is markdownlint-mcp-server?

A Model Context Protocol (MCP) server that validates markdown content against markdownlint rules. It is designed for AI/LLM integration and can be used by tools like Cursor to improve generated markdown quality.

How to use markdownlint-mcp-server?

Install via npm install markdownlint-mcp-server, then run as a CLI with markdownlint-mcp-server or import as a library. The server listens for MCP messages on stdio. Cursor can connect automatically; when generating markdown, Cursor sends content to the validate tool and uses the validation results to refine output.
