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.

deps_audit Read-only

Health verdict for every package in a manifest or a list, in one call (≤25 packages): deprecated / archived / stale / active / unknown per package with the latest version, release and push ages, advisory counts and replacements, plus a summary. Use when reviewing a repository's package.json or requirements.txt before an upgrade, an audit or a fork decision.

task_contextstring, required

One sentence on what the user is ultimately trying to do (the task this call serves). Required; it tunes the result and is how this free service learns what agents need.

manifeststring

Raw package.json (dependencies, devDependencies, peer, optional) or requirements.txt text; other formats are reported as unparsed.

packagesarray

Explicit list of packages; combine with or instead of `manifest`.

package_health

Is this package alive? One verdict — deprecated, archived, stale, active or unknown — with the evidence: per-version deprecation from the native registry, yanked/retracted latest release, repository archived and last-push dates, maintainer and dependent counts, advisory ids for the exact version, and what replaced it. Use when choosing, pinning or upgrading a dependency in npm, PyPI, crates.io, RubyGems, Go, Maven, NuGet or Packagist.

read-only

Argument	Type	Description
name*	string	Package name as the registry spells it: "@scope/name", "requests", "serde", "rails", "github.com/gorilla/mux", "org.apache.commons:commons-lang3", "Newtonsoft.Json", "monolog/monolog"
version	string	The exact version you use or intend to pin; enables per-version advisories and deprecation. Omit for the latest.
ecosystem*	string	npm \| pypi \| cargo (crates.io) \| rubygems \| go (module path) \| maven (group:artifact) \| nuget \| packagist (vendor/package)
task_context*	string	One sentence on what the user is ultimately trying to do (the task this call serves). Required; it tunes the result and is how this free service learns what agents need.

runtime_eol

Support and end-of-life dates for a runtime, OS, database or framework version from endoflife.date (470+ products): each cycle with a verdict — supported, security-only or eol — the latest patch, LTS flag and days to EOL. Use when deciding which Node, Python, Ubuntu, PostgreSQL, Java, Django… version to target or whether a deployed one is still safe.

read-only

Argument	Type	Description
cycle	string	One release cycle to report, e.g. "22" for Node 22, "3.12" for Python, "24.04" for Ubuntu. Omit for every cycle.
