`notary_check_packages`Use when the user or an agent is about to install or import npm or PyPI packages: before npm install or pip install, when adding lines to package.json or requirements.txt, or when a package name came from an AI answer, a tutorial or memory and may be invented. Looks each name up in the live registry and returns whether it exists, the latest version, whether a pinned version exists, weekly downloads, first and last publish dates, deprecation or yanked status, install-time scripts, whether the name is one or two typed characters from a well-known package, and real similar packages when the name does not exist. Example: {"packages":[{"ecosystem":"npm","name":"@anthropic/mcp-client"},{"ecosystem":"pypi","name":"requests","version":"2.32.3"}]}. Up to 10 packages per call; versions must be exact, not ranges. Not a malware or vulnerability scan: "ok" means it exists and nothing looked wrong.
