Overview

Fetch normalized crates.io package metadata including versions, downloads, licenses, repository links, keywords, and descriptions. This first-party Better Fetch tool turns a focused request into predictable structured output that can be inspected in the web workspace, exported as JSON or CSV, called through REST, or composed by an AI agent over MCP. It is designed for repeatable production research rather than fragile copy-and-paste scraping.
