Unmeasured means there is not enough evidence to decide. How these checks work

Inspect individual checks 22 recorded

Core

  • Fail
    Reachable

    Latest probe outcome is ok, HTTP 200.

  • Pass
    Valid handshake

    protocolVersion 2025-06-18, serverInfo.name flyn.

  • Pass
    Lists tools

    tools/list returned 8 tools.

  • Pass
    Current protocol

    Negotiated 2025-06-18. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 12129 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 12129 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    62 of 62 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-08-20T11:30:04.227126Z, within 180 days.

Capabilities

Tools 8

create_qr_code

Render a QR code for any of six content types: a link, plain text, a v-card contact, a pre-filled email, a phone number, or a pre-filled SMS. The image is returned as a PNG you can look at. Nothing is stored, so this code is STATIC: it encodes the content directly and cannot be changed after it is printed. If the user wants a code they can repoint later, or wants to count scans, create a short link with create_short_link first and then call get_link_qr_code instead. Link and Text work on every plan; V-card, E-mail, Call and SMS require Flyn Pro, as do custom colours and SVG output. WiFi codes contain the network password, so they are made in the Flyn dashboard's QR builder, not through this tool: never ask the user for a WiFi password.

Discovered
create_short_link

Create a new Flyn short link that redirects to a destination URL. Returns the link id, slug, and full short URL. The destination is scanned with Google Safe Browsing before creation. Free accounts can create 25 links per calendar month; click limits, fallback URLs, weighted rotation, and conversion tracking require Flyn Pro. Password protection is set in the Flyn dashboard, not through this tool, so never ask the user for a link password.

Discovered
delete_link

Permanently delete a short link. The short URL immediately stops redirecting and this cannot be undone.

Discovered
get_link

Fetch one short link by its id, including destination, settings, total click count, and its conversion counters (conversionTracking, conversions, conversionValueCents).

Discovered
get_link_analytics

Fetch click events for a short link, newest first. Every plan sees timestamps and total counts; country, city, device, OS, browser, and referrer detail requires Flyn Pro (fields are null on the free plan). Free plans see the last 30 days of history. Click events carry no conversion data: for conversions and total conversion value, read the link itself with get_link or list_links.

Discovered
get_link_qr_code

Render a scannable QR code for an existing Flyn short link. Because the code encodes the short link rather than the destination, you can repoint the link later and every printed code follows, and each scan is counted as a click. The image is returned as a PNG you can look at. Custom colours and SVG output require Flyn Pro.

Discovered
list_links

List the account's short links with pagination, search, and filtering. Returns each link's id, slug, short URL, destination, click count, and settings, plus its conversion counters: conversionTracking (whether the link carries a click id), conversions, and conversionValueCents (total value reported for those conversions, in cents, not currency converted).

Discovered
update_link

Update an existing short link. Can re-point the destination URL without changing the printed/shared short link, plus edit title, slug, tags, expiration, rotation destinations, and Pro settings. Only the provided fields are changed. Link passwords are managed in the Flyn dashboard, not through this tool.
