## What it is
mgrep is a CLI tool by Mixedbread that provides semantic, natural-language search over local files including code, text, PDFs, and images. It uses background indexing via 'mgrep watch' to keep a Mixedbread store up to date, supports web search, and integrates with coding agents to reduce token usage.

## Use cases
- semantically search a codebase with natural language queries
- find where authentication is set up in a repo without knowing keywords
- search PDFs and images alongside code from the terminal
- index a git repository in the background for instant semantic lookup
- give coding agents a semantic search tool to reduce token usage
- search the web together with local files

## When to choose
- you want grep-like speed but with natural-language, semantic queries
- you work across mixed file types like code, PDFs, and images
- you want to equip AI coding agents with efficient repo search
- you prefer a CLI-native workflow with background indexing

## When to avoid
- you need fully offline search without a Mixedbread account or API key
- you only need exact string/regex matching, which plain grep handles well
- you cannot send your code or documents to a cloud service
