Overview

Description from the maker (original English)

31 no-AI tools: image conversion and EXIF stripping, App Store assets, colour maths. No API key.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Design, images & audio

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 2 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 31 things (tools) estimate_ai_tokens, generate_app_icon_set, build_app_store_link, calculate_app_store_net_revenue …
  • The registry lists no key to fill in.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 9, 2026. The maker wrote them, not us; we show them as plain text.

  • estimate_ai_tokens

    Heuristic estimate (NOT a real per-model BPE tokenizer) of how many tokens a piece of text will become, ported from GO AI's browser-side token counter. Blends a chars/4 and words/0.75 baseline with surcharges for punctuation, digits and non-Latin script; typically within ±10-15%

  • generate_app_icon_set

    Turns one source image into a ZIP containing a complete iOS Xcode AppIcon.appiconset (AppIcon.png at 1024x1024, plus a hand-written Contents.json Xcode accepts, and optionally AppIcon-Dark.png and AppIcon-Tinted.png for the appearance variants modern iOS asks for), a full Android

  • build_app_store_link

    Builds a correct apps.apple.com URL for an app ID or a pasted App Store URL, in a chosen two-letter storefront, with optional App Store Connect campaign attribution parameters (pt, ct, and mt=8). Always returns the assembled URL and a params table describing what each part does.

  • calculate_app_store_net_revenue

    Computes what a developer actually receives from an App Store sale: first removes the storefront's VAT/GST already baked into the customer-facing sticker price, then applies Apple's commission (standard 30%, Small Business Program 15%, or the post-year-one subscription 15%) to th

  • appstore_search

    Searches one Apple App Store country storefront by term, via Apple's public iTunes Search API (the same request the GO AI "App Store storefront checker" tool makes from the browser), and returns matching apps with title, seller, price, rating and a direct App Store link. Returns

  • appstore_compare_markets

    Looks up one app (by numeric App Store id, or a pasted apps.apple.com URL) in up to 30 App Store storefronts in a single call, via Apple's public iTunes Lookup API, and reports per-market availability, localized title, price and rating. Capped at 30 storefronts per call by design

  • calculate_bmi_and_body_fat

    Computes BMI (with its standard weight-category label) and body fat percentage via the US Navy circumference method from height, weight, neck, waist, and (for females) hip measurements, plus the resulting lean body mass. The Navy equations are fitted in inches, so metric inputs a

  • bpm_delay_calculator

    Resolves a musical tempo — either a direct BPM, or a set of tap timestamps/intervals run through the same median-filtered outlier rejection and 2-second session-reset logic as GO AI's tap-tempo tool — then returns the full straight/dotted/triplet delay and LFO-rate table (ms and

  • css_clamp_calculator

    Generates a CSS clamp() declaration (in rem) that linearly interpolates a size between a value at a small viewport width and a value at a large one, exactly matching GO AI's clamp() calculator tool (same slope/intercept math, rounded to 4 decimal places). Returns a status: 'sameV

  • image_compress

    Downscales an image to fit within a maximum dimension (default 1600px on the longer side, never enlarges -- matching GO AI's browser compressor tool) and re-encodes it as JPEG, WebP or AVIF at a given quality (1-100 scale, default 75). Input is base64-encoded image bytes (any for

  • image_compression_curve

    Analysis-only tool (no image bytes returned): re-encodes an image at the same fixed 14 quality levels GO AI's browser compressor samples to draw its size-against-quality curve (5, 10, ..., through 100 -- see the qualities in each returned point), for JPEG, WebP or AVIF, and repor

  • check_contrast

    Computes the WCAG 2.x contrast ratio between a foreground (text) and background hex colour, and reports AA/AAA pass or fail for normal text, large text, and UI components (icons/borders/focus rings) separately, since WCAG grades each case on its own threshold. Also reports the ne

  • find_nearest_passing_color

    Given a foreground/background hex pair, moves only the lightness of one side (hue and saturation held fixed) in the smallest step that clears a target WCAG contrast ratio, so a failing brand colour can be fixed without draining its hue. Defaults to the 4.5:1 normal-text AA thresh

  • strip_image_metadata

    Reads a JPEG or PNG's hidden metadata (JPEG: EXIF — camera make/model, lens, body/lens serial numbers, capture date, GPS coordinates and altitude — plus XMP, IPTC/Photoshop resources and comment segments; PNG: tEXt/iTXt/zTXt/eXIf/tIME chunks) and returns a structured report of ex

  • generate_favicon_set

    Turns one source image into a complete favicon set: favicon.ico (a real multi-resolution ICO container holding 16, 32 and 48px PNG-encoded entries -- not a single-size file with an .ico extension), favicon-96x96.png, apple-touch-icon.png (180px, flattened onto backgroundColor bec

  • project_weight_goal_date

    Projects the calendar date a goal body weight is reached under a fixed daily calorie intake. Unlike a naive straight-line calculator (kg to lose x 7700 / deficit, also returned here for comparison), this recomputes Mifflin-St Jeor maintenance calories at each simulated day as wei

  • convert_heic_to_jpg_png

    Converts iPhone HEIC/HEIF photos to JPEG or PNG, decoding with a WebAssembly build of libheif (LGPL-3.0) and re-encoding with sharp -- the same pipeline as GO AI's browser-based HEIC converter tool, run server-side. Accepts 1-50 files as {filename, dataBase64} (each up to ~30MB d

  • inspect_mobileprovision

    Reads an iOS/macOS provisioning profile (.mobileprovision or .provisionprofile, given as base64) by byte-searching its CMS/PKCS7-signed container for the embedded '<?xml ... ' property list and parsing that XML -- it never validates or decodes the cryptographic signature, and doe

  • recommend_ai_model

    Static editorial recommendation -- NOT a live benchmark or leaderboard -- for which of six AI models (GPT-5, Gemini, Grok 4, Claude, DeepSeek, Kimi) to use for a given kind of task, ported from GO AI's own daily side-by-side-use judgement, current as of August 2026. Pick a task a

  • oklch_convert

    Converts a color to and from OKLCH. Accepts either a CSS color string via `color` (hex, rgb()/rgba(), hsl()/hsla(), or oklch()) or explicit OKLCH lightness/chroma/hue via l, c and h — supply one or the other. Returns the canonical oklch() text for the color exactly as requested,

  • oklch_ramp

    Builds a perceptually even OKLCH swatch ramp from a base color (same `color` or l/c/h input as oklch_convert) by sweeping one channel — hue, lightness, or chroma — while holding the other two fixed, so every swatch keeps the same visual weight (this is the reason to build a ramp

  • plant_watering_calendar

    Builds a soil-check interval per houseplant from a fixed drought-tolerance table (32 common houseplants), adjusted by pot size, pot material, light and season, and returns both a schedule breakdown and the full text of a downloadable RFC 5545 .ics calendar file -- one recurring a

  • build_app_privacy_label

    Given which SDKs and features are present in an iOS app (analytics, crash reporting, ads, attribution, accounts, in-app purchases, location, HealthKit, contacts, search, etc.), returns the App Store Connect privacy data types those items most likely require declaring, grouped the

  • recipe_convert_ingredient

    Converts an amount of one ingredient between cup, tablespoon, teaspoon, millilitre, gram and ounce using that specific ingredient's own USDA FoodData Central portion weight, not a single water-based figure applied to everything -- a cup of flour (125 g) and a cup of honey (339 g)

  • recipe_scale

    Scales a pasted recipe (one ingredient per array entry, e.g. '2 cups all-purpose flour') from one servings count to another, multiplying each line's leading amount by the ratio and reformatting it as a whole number or simple/mixed fraction rather than a decimal. When a line's uni

  • resize_images

    Resizes a batch of 1+ images to a named real-world preset (App Store screenshots, Open Graph/social cards, Android launcher icon densities, a favicon set) or a custom width/height, using contain (whole picture, padded), cover (fills the frame, crops overflow) or stretch (distorts

  • render_app_store_screenshot

    Composite one or more app screenshots into a drawn device frame (rounded bezel, Dynamic Island on phone-shaped canvases) with a gradient background and optional headline/caption text, and export as PNG at any/all of the 4 official App Store Connect sizes. A blank page (image omit

  • check_strings_files

    Compares two or more iOS Localizable.strings files (sent as base64-encoded raw file bytes, not text) against a base file and reports keys missing from each other file, keys present in another file but not the base ("extra", reported but not counted toward the issue total), values

  • calculate_tdee

    Calculate Basal Metabolic Rate with Mifflin-St Jeor and Harris-Benedict (plus Katch-McArdle when body_fat_percent is given), then Total Daily Energy Expenditure, a goal-adjusted calorie target (cut/maintain/bulk), and a protein/fat/carb macro split, from sex, age, height, weight

  • convert_video_to_gif

    Ports GO AI's browser Live Photo-to-GIF tool server-side: trims a SHORT video clip and converts it to an animated GIF, or (a server-side addition the browser tool cannot do) a real MP4/WebM video. Input is base64 video bytes plus its mimeType (any container/codec this server's ff

  • estimate_window_light

    Estimates the indoor light level a window gives a plant, in the category words houseplant care guides use (Direct sun / Bright indirect / Medium light / Low light / Too dark), from the window's hemisphere, compass aspect, what obstructs it, and how far back the plant sits from th

Common questions

Is GO AI Tools safe?

It passed 2 of 3 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 –, and the latest version (1.0.0) reached the registry 2 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 in developer mode.

What can I use instead?
