    How to connect

    How to connect Sighttrue to Claude

    The server address to paste into Claude settings:

    https://sighttrue.com/api/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect Sighttrue to ChatGPT

    The server address to paste into ChatGPT settings:

    https://sighttrue.com/api/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    check_before_installCall 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 Returns only the facts a reviewer would be annoyed to discover afterwards: whether the publisher has withdrawn the package, whether it runs scripts on the installing machine, whether its repository is archived, how many advisories are on record, whether the licence is source-available, and how long since it was actually published. Each fact carries the address of the body that published it. It does not say whether to install; it says what is on record.
    check_packageRead 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_stackRead 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_repositoriesFind watched repositories whose name contains a string, with their current readings. Use it to discover what is covered before calling the other tools.
    compare_repositoriesHold 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_modelFind 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_eolCheck 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_providerRecorded incidents for a hosting or API provider over a window, kept after the provider’s own status page dropped them.
    list_readingsList 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_publishHow 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_historyHow 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_installedPackages 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_checkWhether 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_gapPackages 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_fixDays 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_severityAdvisories broken down by severity rather than counted, with identifiers and dates. Requires a key; see https://sighttrue.com/pricing.
    runtime_deadlinesSupport end dates for the runtimes a dependency set requires, including any already past. Requires a key; see https://sighttrue.com/pricing.
    base_image_checkFor 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_healthRecorded outages of the package registries themselves, kept after their status pages drop them. Requires a key; see https://sighttrue.com/pricing.
    provider_incidentsA 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_transparencyHow 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_changedWhen 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_historyEvery recorded price for a model, with the date each was read. Requires a key; see https://sighttrue.com/pricing.
    model_withdrawnModels that were in the catalogue and no longer are, with the date last seen. Requires a key; see https://sighttrue.com/pricing.
    help_availabilityFor a technology tag: questions asked against questions answered, over time. Requires a key; see https://sighttrue.com/pricing.
    audit_manifestRead 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_sinceWhat changed for a set of packages since a given date, read from the daily archive. Requires a key; see https://sighttrue.com/pricing.
    watch_addAdd 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_changesEverything 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_findingGiven 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_riskWhether the domains a package points at — homepage, funding, documentation — still resolve to a registered owner. Requires a key; see https://sighttrue.com/pricing.
