What it can do

Tool names and descriptions exactly as the server reported them on Nov 11, 2026. The maker wrote them, not us; we show them as plain text.

  • check_before_install

    Call this before adding a dependency. Returns only the facts a reviewer would be annoyed to discover afterwards: whether the publisher has withdrawn the package, whether it runs scripts on the installing machine, whether its repository is archived, how many advisories are on reco

  • check_package

    Read the current standing of one open-source package: downloads with the window they cover, OpenSSF scorecard, advisory count, licence, whether the repository is archived, and when it was last pushed to.

  • check_stack

    Read a whole dependency list at once and report what is archived, what carries advisories, what has a source-available licence, and what has not been pushed to in a year. Use when reviewing a package.json, requirements.txt, Cargo.toml, composer.json or Gemfile.

  • search_repositories

    Find watched repositories whose name contains a string, with their current readings. Use it to discover what is covered before calling the other tools.

  • compare_repositories

    Hold two watched repositories against each other across downloads, OpenSSF scorecard, advisories, forks, stars and findings on record. Compares only; it does not pick a winner.

  • find_model

    Find language models by price and context window, from a catalogue read daily across sixty providers. Use this before choosing a model: prices move without announcement and training data is out of date on the day it ships.

  • check_eol

    Check whether a runtime, database or framework release is still receiving security fixes, and what to move to. Covers about two dozen products read daily from endoflife.date.

  • check_provider

    Recorded incidents for a hosting or API provider over a window, kept after the provider’s own status page dropped them.

  • list_readings

    List every reading this server can return, what each one measures, and which require a key. Call this first if unsure which tool answers a question.

  • who_can_publish

    How many accounts hold publish rights on a package, as the registry lists them. Answers who can put code on your machine, which is a different question from who writes it. Requires a key; see https://sighttrue.com/pricing.

  • package_weight_history

    How the published artefact size has moved over time. Returns the readings taken, not a verdict. Requires a key; see https://sighttrue.com/pricing.

  • withdrawn_but_installed

    Packages whose own publisher has withdrawn them and which are still being installed heavily, with the download figure and the publisher’s notice. Requires a key; see https://sighttrue.com/pricing.

  • typosquat_check

    Whether a name is one edit away from a more widely installed package. States that both names exist; which one was meant is the caller’s call. Requires a key; see https://sighttrue.com/pricing.

  • funding_gap

    Packages that ask for funding, beside how heavily they are installed and how many people write them. Requires a key; see https://sighttrue.com/pricing.

  • time_to_fix

    Days between an advisory being published and a release appearing that postdates it, per package and as a distribution. Requires a key; see https://sighttrue.com/pricing.

  • advisory_severity

    Advisories broken down by severity rather than counted, with identifiers and dates. Requires a key; see https://sighttrue.com/pricing.

  • runtime_deadlines

    Support end dates for the runtimes a dependency set requires, including any already past. Requires a key; see https://sighttrue.com/pricing.

  • base_image_check

    For a container base image: its size, when it was last rebuilt, and whether the OS underneath it is still supported. Requires a key; see https://sighttrue.com/pricing.

  • registry_health

    Recorded outages of the package registries themselves, kept after their status pages drop them. Requires a key; see https://sighttrue.com/pricing.

  • provider_incidents

    A provider’s recorded incidents, grouped by the component that failed, over the whole archive rather than the window its status page shows. Requires a key; see https://sighttrue.com/pricing.

  • provider_transparency

    How long a provider takes to acknowledge an incident: the interval between an incident starting and its first public update. Requires a key; see https://sighttrue.com/pricing.

  • provider_terms_changed

    When a provider last changed its terms or pricing page, from a stored fingerprint of the page. Requires a key; see https://sighttrue.com/pricing.

  • model_price_history

    Every recorded price for a model, with the date each was read. Requires a key; see https://sighttrue.com/pricing.

  • model_withdrawn

    Models that were in the catalogue and no longer are, with the date last seen. Requires a key; see https://sighttrue.com/pricing.

  • help_availability

    For a technology tag: questions asked against questions answered, over time. Requires a key; see https://sighttrue.com/pricing.

  • audit_manifest

    Read a whole manifest and return every reading on record for it, ordered by how much a reviewer would want to know. One call instead of one per dependency. Requires a key; see https://sighttrue.com/pricing.

  • diff_since

    What changed for a set of packages since a given date, read from the daily archive. Requires a key; see https://sighttrue.com/pricing.

  • watch_add

    Add a package to the caller’s own private watchlist, so later readings are about their stack rather than the public one. The list is private to the key that created it. Requires a key; see https://sighttrue.com/pricing.

  • watch_changes

    Everything that has changed across the caller’s private watchlist since a given date: withdrawals, licence changes, advisories, archived repositories and runtimes going out of support. Requires a key; see https://sighttrue.com/pricing.

  • explain_finding

    Given a finding id, return what was measured, when, by whom, and the address it can be checked at. For an agent quoting a figure into a review. Requires a key; see https://sighttrue.com/pricing.

  • domain_risk

    Whether the domains a package points at — homepage, funding, documentation — still resolve to a registered owner. Requires a key; see https://sighttrue.com/pricing.

Common questions

Is Sighttrue safe?

It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed yesterday, and the latest version (1.0.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?

permissions:

pull-requests: write # only needed for the comment

steps:

  • uses: actions/checkout@v4
  • uses: sighttrue/sighttrue@v1 with: manifest: package.json fail-on: withdrawn,archived,relicensed

Fails the build when a dependency's own publisher has withdrawn it — npm calls it deprecated, PyPI and crates.io call it yanked, RubyGems yanked, Packagist abandoned, NuGet deprecated — or when its repository has been archived or moved to a source-available licence, and reports advisories either way. Reads package.json, requirements.txt, pyproject.toml, Cargo.toml, composer.json and Gemfile. No key, no account, no service to sign up to — it reads published measurements and talks to OSV. A network problem is never a finding: if the readings cannot be fetched the step says so and passes, because a build that breaks when somebody else's site is down is a build that gets deleted.

On a pull request it also leaves a comment with the findings as a table, and rewrites that same comment on every push rather than adding another. A red build tells a reviewer that something is wrong; it does not tell them which dependency, or what changed about it, without opening the log. Set comment: false to report only in the step summary. A pull request from a fork gets a read-only token, so the comment is skipped there and the step still passes.

Also runs against requirements.txt and Cargo.toml.

Or install the App and change nothing

The Action needs a workflow file in every repository that wants it. The GitHub App needs one install and then watches every repository it is given, with no workflow, no key and no configuration: when a pull request adds a runtime dependency that is on the watchlist, it leaves one comment with what is on record — downloads, OpenSSF scorecard, advisory count, licence, last push — and edits that same comment on every later push.

It says nothing at all when a pull request changes no manifest, adds no dependency, or adds nothing that is tracked. That is the common case and it is the point: a bot that comments to say it found nothing gets uninstalled. It never calls a package safe, unsafe or recommended, because none of those are things this project measures.

The Action fails a build; the App only reports. Both read the same published bundle, so they cannot disagree.

An SBOM you are allowed to hand over

/stack exports the readout as a CycloneDX 1.6 document, with each dependency's advisory count, scorecard, licence, publish date and bus factor attached as properties. Built in the browser from the pasted manifest, like everything else on that page — nothing is uploaded, and there is no endpoint to send a manifest to.

It states no versions. A manifest declares ^1.6.0; it does not say what was installed, and it says nothing about the transitive tree underneath. The document says both of those things in its own metadata rather than leaving a reader to notice, because an SBOM that guessed would be worse than none: a compliance artefact asserting something nobody resolved.

Suggest something to watch

The watchlist is curated and partial, and it was chosen by hand with no method beyond judgement — its weakest point. Open an issue to argue for a repository. Every change to the list is a reviewed commit, so that issue is where the review happens.

For coding agents

An MCP server over the same readings, so an agent can answer "is this dependency healthy" from a measurement taken today rather than from training data a year old.

{ "mcpServers": { "readout": { "url": "https://sighttrue.com/api/mcp" } } }

Nine tools free, twenty-two paid. check_before_install is the one to reach for while writing code: given a package it returns only what a reviewer would be annoyed to discover afterwards — a publisher that withdrew it, scripts it runs on the installing machine, an archived repository, advisories, a source-available licence, a long silence — each with the address of the body that published it. It does not say whether to install. It says what is on record so the decision is made knowing it, and an empty result says plainly that it means nothing was found rather than that the package is safe.

Then check_package, check_stack, search_repositories, compare_repositories, find_model, check_eol, check_provider, list_readings . Read-only, no key, no account. Every result carries the limits of what it can support, because an agent will paste these figures into a code review and a scorecard quoted without "measures declared practices, not whether the project is safe" is a claim this project does not make.

Without MCP, one GET returns the same thing:

curl 'https://sighttrue.com/api/verdict?pkg=npm:axios'

curl 'https://sighttrue.com/api/verdict?pkg=pypi:django&version=4.2'

Advisories, licence, when the registry last shipped it, the bus factor, and whether the release is still supported — each with the address of the body that published it, so a figure quoted into a review can be checked in one click. Despite the name there is no verdict in it: no score, no rank, no recommendation. Those would be this project's judgement of somebody else's work wearing the costume of a measurement.

One agent watches 417 open-source repositories and takes eleven readings, most of which never touch GitHub: 807 provider incidents kept after their own status pages dropped them, 522 release lines on the end-of-life clock, 382 model prices, 182 packages by real ship date, 416 commit histories for the bus factor. It runs every four hours on GitHub Actions, commits what it reads to this repository, and publishes a static site.

Every page and every bundle is a file. There are five dynamic routes and no page depends on any of them: /api/ask, /api/mcp, /api/chain, /api/github/webhook for the App, and the sign-in and watchlist endpoints under /api/auth and /api/watchlist. Signing in with GitHub saves a watchlist and nothing else — the readings on a signed-in page are the same published bundle anyone can download.

The commit history of data/ is the point. It is an audit trail: every reading is timestamped, append-only, and checkable against GitHub directly.

What it reports

Eleven readings, each named by the question it answers rather than by the collector that produces it. The same list drives the site's navigation, so the two cannot drift — they had, three times over, before it was written down once.

ReadingQuestion it answersTouches GitHub

The six that never touch GitHub are the answer to the fair complaint that a GitHub summariser is worth only what GitHub already shows you.

Whether each detector's threshold is reachable at all is published too, on the index under Our record. A detector nothing has ever come close to is not a quiet detector, it is a misconfigured one, and the site says so about itself.

How to read it

Every comparison is against a repository's own history, not against other repositories. "27× baseline" means 27 times what that project normally does, and the baseline is drawn on the chart so you can see what normal means.

Confidence is stated, never implied.

StateMeaning
formingUnder 14 days of history. Raw counts only. No multiplier is computed and none is implied.
detectedCrossed the threshold once. Neutral treatment.
confirmedPersisted across two consecutive daily snapshots.

Only confirmed signals are treated as findings. That costs up to a day of speed and buys the thing that cannot be bought back.

Generated prose is set in a different typeface from measured values. Where a sentence explains a number, every figure in that sentence is checked against the source record before it is published; if any of them is not in the record, the sentence is discarded and a templated one is used instead.

What this does not claim

  • The watchlist is curated and partial. It is chosen by hand and is not a survey of open source. Dependency and demand findings describe the repositories being watched, not the ecosystem.
  • The data is not real-time. Four hours is the floor, and scheduled runs are routinely delayed.
  • Nothing here predicts anything, and nothing here says a repository is good, bad, safe, or unsafe.
  • Appearing on the watchlist is an observation, not a relationship. No project listed here has endorsed this.

Published findings that turn out to be wrong are superseded by a correction event carrying the same prominence. Events are never deleted and history is never rewritten.

The data

Every bundle the site reads is served as JSON, so any claim can be checked against the same file the page used.

data/

├── live/state.jsonl Latest reading per repository. Sorted, rewritten each pulse. ├── live/window.jsonl Timestamped fork samples, for the rolling 24h delta. ├── live/manifests.jsonl Last-seen dependency set, diffed daily. ├── history/YYYY-MM-DD.jsonl One immutable snapshot per day. ├── events/YYYY-MM.jsonl Append-only. Never rewritten, never pruned. ├── summaries.jsonl Generated prose, keyed by event id. ├── watchlist.jsonl What is watched, and since when. └── meta.json Last run status.

Files are sorted with a fixed key order so a repository that did not change produces no diff. That is what keeps a repository committed to six times a day from growing without bound.

Running it

Node 24. Types are stripped natively, so there is no build step and no runtime dependencies.

It said 22.18+ until the D1 schema arrived. The tests load migrations/ into node:sqlite, which is stable in 24 and behind a flag in 22 — so on 22 the suite fails on an import rather than on an assertion, which is a confusing way to learn a version requirement.

npm install          # dev dependencies only: typescript, vitest, fonts

npm test npm run typecheck

node scripts/pulse.ts --limit=20 # needs GITHUB_PAT node scripts/daily.ts node scripts/build.ts # emits dist/

Watchlist maintenance

The watchlist is curated. Deriving it from a search query was tried and produced a worse list — topic search only finds repositories that tagged themselves, and sorting by stars ranks tutorials and link collections above infrastructure. derive-watchlist.ts is kept for proposing candidates a curator might have missed, and because the negative result is worth being able to reproduce.

node scripts/verify-watchlist.ts   # check every entry against the API

node scripts/retire-watchlist.ts # mark archived and deleted ones inactive node scripts/derive-watchlist.ts # propose candidates, writes n
