Tools

Search and download arXiv papers and read the authors' LaTeX source section by section, export BibTeX and follow topic updates, with papers cached locally. No API key needed.

Microsoft's official skill collection: 170+ skills focused on Azure SDKs (Python, .NET, TypeScript, Java, Rust) and Microsoft Foundry development, plus plugins, custom agents and MCP configs. Microsoft recommends picking skills per project rather than installing them all.

Agent skills maintained by the Flutter team: layered architecture, responsive layouts, fixing layout overflows, declarative routing, internationalization, JSON serialization, and widget and integration tests. Works alongside the Dart MCP server.

Official plugin from the Dart and Flutter teams that installs Flutter skills and the Dart MCP server together, covering layered architecture, responsive layouts, layout error fixes, widget and integration tests, routing and internationalization. Requires the Dart/Flutter SDK locally.

Reviews mobile and desktop app designs against Apple's Human Interface Guidelines, bundled as 123 pages from developer.apple.com, citing the exact guideline through five review lenses, and flags generic, templated choices. Works on screenshots, mockups or code for SwiftUI, Flutter or Electron.

Measurement-first audits and optimization of web quality using Lighthouse, Chrome DevTools performance traces and CrUX data, covering Core Web Vitals, WCAG 2.2 accessibility, SEO and best practices, for any frontend framework. By Addy Osmani (not an official Google project).

Unified search across 20+ academic sources including arXiv, PubMed, bioRxiv, Semantic Scholar and OpenAlex, returning deduplicated, normalized results and downloading full text via open-access channels first. Most sources need no API key.

Replaces arXiv preprint entries in your .bib file with the official published versions from DBLP and ACL Anthology, keeping citation keys, to tidy references before camera-ready. Overwrites the file by default, so preview with --dry-run. Mainly covers CS venues; needs Python 3.10+.

Postgres rules ranked by impact: query optimization, indexing, connection pooling, RLS security, schema design and lock troubleshooting, with wrong-vs-right SQL examples, applicable to any Postgres. Maintained by Supabase.

Connects to your Supabase projects: manage schemas and migrations, run SQL, deploy Edge Functions, create development branches and generate TypeScript types. A remote server hosted by Supabase with OAuth sign-in.

Open-source, agent-friendly BI: define metrics and dashboards in YAML and SQL, and rill init generates project instructions and MCP config for Claude Code so agents can build business dashboards and answer questions in natural language. Local use is free; publishing to Rill Cloud needs an account.

Open-source meeting bot and real-time transcription platform: sends a bot into Google Meet, Teams or Zoom and transcribes live by speaker, with MCP so agents can dispatch bots and read transcripts. Use the hosted service (API key) or self-host.

Supermemory's official Claude Code plugin: hooks save memories automatically when a session ends and recall them on demand, giving persistent memory across sessions and projects, with shared project memory for teams. Needs a Supermemory API key and Node.js 18+.

Google's official terminal coding agent and successor to Gemini CLI: understands your codebase and, with your approval, edits files and runs commands. Shares its engine and settings with the Antigravity 2.0 desktop app. Closed source; sign in with a Google account; free tier included.

Plugin marketplace for multi-agent dev workflows: omo multi-agent orchestration, BMAD agile role flows, requirements-driven development, SPARV and common dev commands, delegating coding tasks to Codex, Claude, Gemini and other backends (their CLIs installed separately). AGPL licensed.

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.

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.

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.

A video production workspace for Claude Code: scripting, AI voiceover, music, generated visuals and Remotion rendering to MP4, with explainer and product-demo templates. The full workflow needs the cloned repo and Node.js 18+; AI generation needs your own cloud GPU (e.g. Modal's free tier).

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.
