## What it is
mq is a jq-like command-line tool and query language for slicing, filtering, and transforming Markdown via its AST, written in Rust as a single native binary. It includes a REPL, LSP support, a debugger, and companion tools such as an MCP server for AI assistants.

## Use cases
- extract all headings from markdown files
- filter and transform markdown documents from the command line
- prepare structured markdown input for LLM prompts
- batch process documentation files
- convert html to markdown
- query markdown like jq queries json

## When to choose
- you already know jq and want the same workflow for Markdown
- you need fast, structural (AST-based) Markdown manipulation without regex
- you process Markdown for LLM pipelines or documentation at scale

## When to avoid
- you need rich-text or WYSIWYG Markdown editing rather than programmatic querying
- your documents are not Markdown and you don't want format conversion
- you need a fully stable, long-term-supported tool given active development

## Facets
- artifact type: cli-tool
- maturity: active
- function: parser, cli, interpreter, markdown, mcp, llm-inference, developer-tools
- domain: developer-tools, large-language-models, documentation
- platform: cli, windows, rust, cross-platform
