Bright Data's official MCP: web search (Google, Bing, Yandex), any page to Markdown, structured data extraction from e-commerce, social and other platforms, and remote browser control. Needs an API token; includes 5,000 free requests a month.

Blog writing and SEO skill suite: /blog commands for strategy, outlines, drafting, rewrites, quality audits, multilingual publishing and refreshing old posts; drafts scoring under 90/100 are reworked. Get the review subagents and scripts via the plugin or install script; needs Python 3.11+.

An end-to-end blogging plugin: topic research, outlines, drafting, rewrites, fact-checking, SEO and AI-citation optimization, plus multilingual publishing. Each post is scored on a 100-point rubric and reworked if under 90. Needs Python 3.11+; optional images and voiceover use a Gemini API key.

Translates a finished blog post into one or more languages while keeping formatting, images and charts, localizes keywords, titles, meta descriptions, dates and currencies per market, and flags sentences that read like machine translation. No account needed; part of the claude-blog suite.

Gives agents on-demand guidance for the modern web platform, covering View Transitions, container queries, Popover, INP optimization, accessibility and more, with browser compatibility data so they avoid outdated code. Maintained by the Google Chrome team; currently in preview.

LLM translator for novels, subtitles, ebooks and game text: one-click glossaries keep names consistent and translations get auto-reviewed. Besides the desktop app it has a CLI (translate/analyze, JSONL status). Download from Releases and bring an LLM API; commercial use needs the author's OK.

Scans codebases and dependencies for open-source licenses, copyright notices and package manifests, detecting licenses by full-text matching, with output in JSON, SPDX, CycloneDX and more, for open-source compliance reviews.

65 skills built on methods from business, marketing and design bestsellers like Influence, StoryBrand and The Lean Startup: positioning, copywriting, conversion optimization, sales negotiation, UX review, plus step-by-step startup and site-building guides. Prompt-only, no API key needed.

Gives agents a live local Excalidraw canvas: add, edit and delete elements to draw architecture diagrams and flowcharts, take screenshots to check the result, convert Mermaid and export .excalidraw files. Runs locally with no API key; also ships a CLI and an agent skill.

Perplexity's official MCP with four tools: web search, grounded Q&A, deep research and reasoning, available remotely or run locally. Requires a Perplexity API key.

Simon Willison's website screenshot CLI: batch screenshots from YAML, record demo videos, export PDF and HTML, run JavaScript in pages to extract data, and dump accessibility trees. Built on Playwright; install a browser on first use.

Runs open image models like FLUX, Qwen Image and Z-Image locally on a Mac: text-to-image, reference-based edits, inpainting and upscaling, all on-device. Needs Apple Silicon and uv; the first run downloads models and is slow. Check each model's license before commercial use.

A Chinese-first editing skill that also works on English: strips boilerplate, padded lead-ins and stiff phrasing while keeping numbers, conditions, commitments and the author's voice. Can flag issues without rewriting. It doesn't detect AI text or promise to evade detectors.

Translates whole EPUB books, Word files, SRT subtitles and TXT with local Ollama or cloud LLMs (OpenAI, Gemini, DeepSeek), keeping layout and timings. Builds a glossary for consistent terms and can resume jobs. Mainly a desktop app; the CLI runs from source; cloud models need an API key.

A research-writing plugin from K-Dense: searches the literature in real time before drafting, then produces papers, reviews, grant proposals, posters and slides with verifiable citations and figures. Literature search needs a Parallel API key; PDF output needs LaTeX.

Two-stage deep research: drafts an editable outline for the topic, then parallel subagents search the web item by item and compile a Markdown report. Good for literature reviews, competitor research and due diligence. Install by copying files per the README, plus pip install pyyaml.

Apify's official skill collection: picks from 130+ curated Actors to scrape public data from social networks, maps, e-commerce sites and more, and can also build, package and deploy Actors. Needs an Apify account; a free tier is available.

Four tools for real-time web search, page content extraction, site mapping and full-site crawling, available as a remote server or run locally. Maintained by Tavily; needs an API key or OAuth sign-in, and a free account is available.

Turns a paper's method description (text or PDF) or data files into publication-ready diagrams and plots, with several AI reviewer roles refining each figure. Needs an OpenAI or Gemini API key (billed per image), Python and uv. A community reimplementation, not by the original paper's authors.

Supabase's official CLI: runs the full backend stack locally (Postgres, Auth, Storage, Edge Functions), manages database migrations, generates types and deploys functions. The local stack requires Docker.

Explains a codebase, feature, command or pull request to someone new to it as a PR Lens canvas: one plain sentence first, then a walkthrough that grows the diagram from two boxes to the whole picture, delivered as a shareable link. Requires the PR Lens skill and its npx CLI.

Draws a code change or part of a codebase as an animated architecture or data-flow diagram. The agent writes a JSON graph, validates and renders it to SVG with the PR Lens CLI, then pushes it to a prlens.dev canvas or attaches it to a GitHub, GitLab or Bitbucket pull request.

Uses hooks to enforce test-driven development in Claude Code: blocks implementation without a failing test, prevents code beyond what tests require, and can use lint results to push refactoring. Needs Node.js 22+. Still maintained, but the author suggests its successor Probity for new projects.

Translates entire books: splits PDF, DOCX or EPUB into chunks for parallel subagents, keeps terminology consistent, resumes interrupted runs and verifies with hashes, then outputs HTML, DOCX, EPUB or PDF. Needs Calibre, Pandoc and Python.
