Microsoft Translator's translation quality tool: GPT scores each sentence using MQM error categories or a direct score; --list_mqm_errors shows error types and severity. Needs line-aligned source and target files, Python and an OpenAI or Azure OpenAI key (paid); a translator should still review.

Styles elevated surfaces such as cards, dialogs, popovers and toasts with smooth-shadow-ring utilities instead of pairing a border or ring with a shadow, avoiding the double-edge look. Covers ring and shadow tinting, dark mode and overrides. Requires the shadow-plugin Tailwind plugin.

Diffs a live page's accessibility violations against a baseline, stashing uncommitted changes by default or comparing with a branch, and reports new, fixed and pre-existing WCAG issues with selectors and fixes. Locates only, no edits. Runs AccessLint's Chrome and CLI tools via npx.

Runs the AccessLint rule engine against a live page and returns a worklist of WCAG 2.2 violations, each with its DOM selector, source file and line when mapped, evidence and a suggested fix. Locates without editing; sets up a debuggable Chrome and runs the CLI via npx.

DeepL's official MCP: translate text and documents (PDF, DOCX, PPTX, XLSX and more) and rephrase or polish writing, using the glossaries and style rules in your account. Needs a DeepL API key.

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.

Sonar's official plugin bringing SonarQube checks into the agent coding loop: secrets-scanning hook, issue fixing, quality gates, coverage and dependency risk; with Vortex analysis on, every edit is checked. Needs SonarQube (free Community Build works), the sonar CLI and Docker.

From Twilio Labs: exposes Twilio's public APIs (SMS, voice, phone numbers, Serverless and more) as MCP tools generated from its OpenAPI specs, with filtering by service or tag. Needs a Twilio API key; marked as a proof of concept.

Strips AI-writing tells from prose while keeping meaning, voice and density: locks facts and quotes, flags filler, inflated significance and formulaic contrast, and rewrites without inventing details. Includes scripts for slop, passive-voice and meaning-preservation checks.

Shapes the agent's own replies rather than your documents: separates what changed from what was verified, cuts invented confidence, leads with the action and keeps load-bearing caveats. Manually invoked and stays on until you say stop; a script can enable it in CLAUDE.md or AGENTS.md.

Neon's official plugin combining the Neon MCP and skills to manage serverless Postgres: projects and branches, object storage, Functions and the AI Gateway. Signs in to Neon via OAuth the first time you use the MCP.
