Pay-per-call x402 npm and PyPI package metadata, versions, search, download counts.
Call this server's tools from your browser. Nothing to install.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Use when you need the public npm registry card for a package (scoped or unscoped): returns description, homepage, bugs URL, repository, license, keywords, maintainers as names only (emails stripped), number of versions, latest dist-tag version, created/modified times, and last-week download count from the official downloads API. Private packages are not supported. Paid tool: x402 USDC on Base, $0.002 per successful call; call without payment to receive the PaymentRequired object.

}Use when you need the exact published artifact for an npm version: dependencies, optionalDependencies, peerDependencies, bundledDependencies, engines, os/cpu, dist (tarball URL, integrity, shasum, unpacked size), and the version publish time. Give "latest" as version to resolve the current dist-tag. Paid tool: x402 USDC on Base, $0.002 per successful call; call without payment to receive the PaymentRequired object.

}Use when you need the public PyPI project card: summary, home_page, project_urls, license, requires_python, a subset of classifiers, requires_dist (capped), current version, and yank status. Author/maintainer emails are omitted or redacted; only display names remain when present.

}Use when you need the published artifacts for a specific PyPI version: each file with filename, packagetype (sdist/bdist_wheel…), size, upload time, yank flags, digests (sha256/blake2b/md5) and download URL. Give "latest" as version to use the project's current version. Paid tool: x402 USDC on Base, $0.002 per successful call; call without payment to receive the PaymentRequired object.

}Use when you have a likely PyPI project name (or a few tokens) and need to resolve it to live projects: tries the query as-is, PEP 503 normalization (lowercase, [-_.] → -), and hyphen/underscore/dot variants, then returns up to "limit" matching projects with summary, version, requires_python and license. This is name resolution, not full-text discovery — prefer exact package names when known. Author emails are redacted.
