Tools

Runs locally with no API key: looks up drug labels and adverse events from FDA, EMA and DailyMed, plus WHO health statistics, PubMed papers, clinical trials and clinical guidelines, with auto-generated evidence-level tags on papers. Needs Node.js. Have a doctor or pharmacist verify results.

Guides building small always-on WebGL visuals (avatars, ambient orbs, glass and iridescent surfaces) inside product UI: one shared context, a single capped frame loop, cheap fragment shaders, context-loss handling, a mandatory non-WebGL fallback, and React SSR and Server Components pitfalls.

Makes the agent use Tailwind container queries instead of viewport breakpoints for responsive components, migrating sm:/md:/lg: classes to @container variants. Explains when page-level layout should keep viewport breakpoints and lists common review mistakes. Tailwind v3 needs a plugin.

Connects to PACS and other DICOM servers: query images by patient, study and series, read text from PDF reports embedded in DICOM, and forward series to AI nodes such as segmentation. Needs uv and a YAML config. Not for clinical use or real patient data (per the author).

Official Google Ads API assistant: ask in plain language, generate and validate GAQL queries, run them to export account data to CSV, and debug offline conversion uploads. Account-changing code is generated, not run. Needs a developer token, credentials file and Python 3.10+.

Analyzes your codebase and generates a render.yaml Blueprint, or creates services directly through the Render MCP, to deploy apps to Render. Maintained by Render and included in OpenAI's curated skills. Needs a Render account and code pushed to GitHub, GitLab or Bitbucket.

Wolfram's official agent tools: use the Wolfram Language and Wolfram|Alpha for symbolic and numeric math and scientific and statistical data, for teaching and research. The command runs the official Docker image with a free developer license; Wolfram 15+ users can install it in the app.

Searches 600,000+ studies registered on ClinicalTrials.gov, shows protocols and posted results (efficacy, adverse events), and matches patients to recruiting trials by age, sex, condition and location. Public data, no API key; needs Node.js 24+. Unofficial; results must be reviewed by a doctor.

PostHog's official plugin with a built-in MCP and 30+ skills: query product analytics, feature flags, A/B experiments, dashboards and error tracking from chat, and optionally send Claude Code sessions to LLM Analytics. Needs OAuth sign-in with a PostHog account.

Fixes janky web animation by moving width, height, position and box-shadow animations onto compositor-only transform and opacity, using pseudo-element opacity for shadows and the FLIP technique for layout changes and height: auto, to reach smooth 60/120fps motion.

Builds animations out of text characters: brightness-ramp mapping with cell aspect correction, generative ASCII fields, image, video and Three.js scene to ASCII conversion, and terminal intros or loaders, rendered with <pre>, canvas or ANSI output.

Applies tiered prefers-reduced-motion handling instead of disabling everything: removes vestibular triggers like parallax and scroll hijacking, softens large movement into short fades, and keeps essential motion. Covers CSS and JS gating for GSAP, Framer Motion and Lenis, per WCAG 2.3.3.

Guides code-driven web motion with GSAP: timelines, ScrollTrigger pinning and scrubbing, horizontal scroll sections, SplitText reveals, Flip layout transitions, and syncing with Lenis or Locomotive smooth scroll to avoid jitter and broken pins.

Integrates Lottie and dotLottie animations from After Effects into web, iOS, Android and React Native: playback and segment control, scroll- or hover-driven interactivity, runtime theming and recoloring, plus an After Effects export checklist.

Implements page and route transitions in the Next.js App Router and fixes Framer Motion exit animations that never fire on navigation, using template.tsx with a pathname-keyed AnimatePresence and FrozenRouter, or the View Transitions API via next-view-transitions.

MLflow's official skills plugin: lets coding agents add MLflow Tracing to LLM apps, analyze failed traces, build evaluation datasets and scorers, and query token and latency metrics, closing the instrument, evaluate, iterate loop. Needs MLflow 3.8+.

Builds frosted and liquid-glass UI: backdrop-filter blur, translucent fills, bright edge highlights and layered shadows, SVG displacement for refraction, hover, scroll and entrance motion, plus accessible reduced-transparency fallbacks.

Adds functional UI micro-interactions with Framer Motion (motion/react) and modern CSS: hover and press feedback, toggles, toasts, drawers, modals, list reorder and shared-element transitions, with 100-250ms timings, asymmetric enter and exit easing, and reduced-motion support.

Animates SVG with stroke draw-on effects, path morphing via GSAP MorphSVG or Flubber, motion along a path, animated icon state changes, and gradient or filter animation, choosing between CSS, SMIL and GSAP per task.

Twelve Data's official MCP: real-time and historical prices for stocks, ETFs, forex and crypto, 60+ technical indicators, plus financials, dividends, fund holdings, company news and SEC filings. Hosted; sign in with your Twelve Data account in the browser, no API key to copy.

UK legal research service from i.AI, the UK government's AI incubator, with a remote MCP: semantic search over UK legislation, amendments and explanatory notes. Connect directly, no account. Officially experimental; case law is temporarily disabled and results need a lawyer's review.

Readwise's official CLI: lets agents search articles and highlights saved in Readwise and Reader, save web pages, tag items and organize reading lists, with a read-only mode to prevent accidental changes. Needs Node.js; Readwise is a paid subscription with a 30-day free trial.

SimpleLocalize's official CLI: upload and download translation files, trigger machine and AI auto-translation, publish translations to the CDN, and extract translation keys from source code for CI. Needs a SimpleLocalize account and project API key; paid service with a 14-day free trial.

Zendesk's official CLI: preview, import and publish Help Center themes locally, and create, package and deploy Zendesk apps such as ticket sidebar apps. Needs a Zendesk account, Node.js 20.17+ and yarn, some HTML/CSS for themes; run zcli login first.
