Fetches US, Hong Kong and China A-share stock data with zero runtime dependencies: real-time quotes, daily, weekly and monthly candles and search as JSON, falling back across Tencent, Sina and Eastmoney sources. Also runs as an MCP server. Unofficial public APIs, no stability guarantee.

A three-stage workflow for math modeling contests like MCM/ICM and CUMCM: analysis, solving and plotting in Python or MATLAB, and a Word (optionally LaTeX) paper, with stage-check subagents and OpenAlex plus AnySearch literature search. Generated papers are for reference only.

Community-maintained Slack MCP: reads channel, DM and thread history, searches messages and fetches unread messages; write actions like posting are off by default and must be enabled explicitly. Works with user OAuth or bot tokens over stdio, SSE or HTTP.

German-language HR plugin for German startups of about 100 people: employment contracts, DATEV payroll handoff, personnel files and data protection, AGG complaints, works councils, absences, benefits and dismissals under German labor law. German law only; have a lawyer or HR pro review.

MathWorks' official server that lets agents start your local MATLAB, write and run scripts and unit tests, and check code style and potential errors, for computing, simulation and data analysis. Needs a licensed MATLAB R2021a+ and the downloaded server binary.

Recommends daily papers from arXiv and Semantic Scholar by research interest, reads them and writes illustrated Obsidian notes and a paper graph; can also search venues like CVPR and NeurIPS. Needs Python 3, Obsidian, a vault path and an interests config; the web app needs an Anthropic API key.

From Harvard Medical School's Zitnik Lab: one MCP connecting 1,000+ scientific tools and databases for drugs and targets, genes and proteins, clinical trials, FDA data and PubMed, for biomedical and drug research. Runs with uv; some sources need API keys; medical conclusions need expert review.

Econometrician Pedro Sant'Anna's academic Claude Code setup (fork the repo to use it): Beamer/Quarto lecture slides, paper review and mock refereeing, R/Python analysis and replication packages, with specialist subagents and quality gates. Needs Git and Python; slides need XeLaTeX and Quarto.

Lets agents drive WinDbg's CDB/KD to analyze crash dumps, debug user-mode processes remotely and debug kernels, and triage many dumps in a batch. Windows only; requires WinDbg or Debugging Tools for Windows.

Uses the Qdrant vector database as a semantic memory layer for agents: store information and retrieve it by meaning, connecting to a remote instance or a local path, with FastEmbed generating embeddings by default. Maintained by Qdrant.

People-management skill pack for managers and HR with 7 skills: performance reviews, performance improvement plans (PIPs), 360-degree feedback surveys, interview scorecards, team health checks, team offsites and a 90-day plan for new managers. Text-only; no account or API key.

HR skills plugin: write inclusive job descriptions, build 30/60/90-day onboarding plans, design and analyze engagement surveys, and plan redundancy consultations (UK employment law by default) and organizational change. Text-only, no account; have legal or senior HR review redundancy plans.

Recruiting and sourcing skills: generate Boolean and X-ray search strings, plan sourcing strategy and draft candidate outreach, plus interview question banks, scorecards, reference-check scripts and offer letters, with an emphasis on structured, fair evaluation. Text-only; no account needed.

Connects LLMs to ROS and ROS 2 robots: publish and subscribe to topics, call services and actions, set parameters, and read sensor and robot state, without changing robot code. The robot side needs rosbridge running.

Hiring lessons from 21 Lenny's Podcast and Newsletter guests on recruiting product managers and engineers: defining the role, sourcing through networks, assessing potential and closing offers, with frameworks and question lists. Methodology-focused, for recruiters and hiring managers.

Collects hiring advice from dozens of Lenny's Podcast and Newsletter guests to help you design realistic work samples or paid trials, shared rubrics and solid reference checks, instead of hiring on interview polish and resumes. Geared to product and tech teams; prompt-only, no account.

76 product skills distilled from Lenny's Podcast and Newsletter, covering product strategy, prioritization, user interviews, PRD writing, OKRs, launches and growth, hiring and team management. Each includes frameworks, checklists and templates, with verified quotes. Docs only, no account.

Helps managers and HR partners prepare tough performance feedback: frameworks like GAIN and Radical Candor, turning judgments into observable facts, role-playing the conversation, and planning follow-up. Distilled from Lenny's Podcast and Newsletter guests; prompt-only, no account needed.

Gives agents controlled access to MySQL: list databases and tables, inspect schemas and sample data, and run SQL, with multi-database mode, SSL and SSH tunnels. Configure your own database user, ideally with least privilege.

Pulls new papers from Hugging Face Daily Papers and arXiv, scores them by research area into a recommendation page, and writes deep-read Obsidian notes for key ones; can also batch-read Zotero collections. Needs Python 3, Obsidian and poppler; copy the whole skills folder per the README.

MathWorks' official toolkit for reading, building, modifying and testing Simulink models via the MATLAB MCP server, with skills for control design, Simscape, code generation and compliance checks. Needs licensed MATLAB R2023a+ and Simulink; run the official installer in MATLAB first.

LangChain's official skill collection: framework selection, quickstarts, middleware, persistence, human-in-the-loop approval, RAG and eval design across LangChain, LangGraph and Deep Agents, in Python and TypeScript. Also installable as a Claude Code plugin. Still in early development.

Connects agents to live Jupyter notebooks: read, write, insert and execute cells and read multimodal outputs like charts, for interactive data analysis. Bring your own JupyterLab or JupyterHub; open source, maintained by Datalayer.

MathWorks' official toolkit: set up the MCP server via the MATLAB installer so agents can run code, run tests and do static checks; domain skill sets for signal processing, controls, statistics and machine learning install as Claude Code plugins. Needs MATLAB R2021a+.
