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.

Converts PDF, Word, Excel, PowerPoint, images, audio, web pages and YouTube transcripts into Markdown that agents can read and cite. Built on Microsoft MarkItDown; the Docker image lacks audio transcription and image recognition, so build locally for full features.

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.

Searches Korean statutes, case law, administrative rules and local ordinances via the Korean Ministry of Government Legislation's Open API, verifies whether cited provisions and cases exist, and compares versions over time. Needs a free API key and Node.js; have a lawyer review results.

Python library with a built-in MCP server for US SEC EDGAR data: search 10-K, 10-Q, 8-K and other filings and read XBRL-standardized financial statements, Form 4 insider trades and 13F holdings. Free with no API key; just set an EDGAR_IDENTITY.

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.

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.

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.

TypeUI's design fundamentals skill: general UI and interaction principles covering visual hierarchy, spacing, typography, 30 laws of interaction and WCAG accessibility. Needs Node.js to install; the TypeUI design-system library needs its hosted MCP and sign-in.

MiniMax's official CLI, built for agents: chat with MiniMax models from the terminal and generate images, video and speech, plus speech transcription, image understanding and web search. Works with the international platform. Requires a MiniMax Token Plan subscription.

A CLI and Python library by Simon Willison: imports JSON and CSV straight into SQLite with automatic table creation, runs in-memory SQL queries over files, and supports full-text search and table transformations.

Figma's official skill for building FigJam boards through the Figma MCP: sticky notes, sections, connectors, shapes and tables for brainstorms, retros and meetings. Needs a Figma account, the remote MCP server and the figma-use skill; canvas writes are free in beta; usage pricing is planned.

Figma's official skill collection: implement designs as code, map components with Code Connect, generate design-system libraries from code, and build screens and FigJam diagrams on the canvas. Needs the Figma MCP server; canvas writes are in beta and currently free.
