The official MCP debugging tool: connect to any MCP server through a web UI, CLI or terminal UI to list and call its tools, resources and prompts. CLI mode outputs JSON, suited to scripts and CI smoke tests.

Following Sahil Lavingia, author of The Minimalist Entrepreneur, helps founders define 3 to 5 concrete company values with real trade-offs before hiring, with example stories and counterexamples, and explains how to use them in hiring and daily work. Prompt-only; no account needed.

Turns terminal output like architecture explanations, diff reviews and plan comparisons into styled HTML pages or slides with zoomable interactive Mermaid diagrams, replacing hard-to-read ASCII diagrams and tables. No build step; open directly in a browser.

UI skills for design engineers: clean up spacing and hierarchy in AI-generated interfaces, fix accessibility and page metadata, debug janky animations, build DESIGN.md from an existing product or site, and run read-only UI reviews with fix plans. Use with a local frontend project in a coding agent.

Builds a scroll-scrubbed fly-through 3D world landing page for any brand: generates scene stills with Higgsfield and seamless camera clips via Monid (Seedance 2.0, paid per clip) or Higgsfield credits, then wires a vanilla JS scrub engine. Needs Higgsfield CLI and ffmpeg.

Publication-quality matplotlib plotting skill from a Yale PhD student: bar charts, trends, heatmaps and multi-panel figures with consistent fonts, colors and export settings, plus real plotting scripts from papers published in venues like Nature Machine Intelligence. Needs Python.

Reads the exact position of every character, line and table cell in digital PDFs: the CLI exports layout-preserving text or CSV/JSON details, and the Python API extracts tables and form fields, ideal for invoices, statements and reports. Runs locally with Python; scans need OCR first.

Generates editable draw.io architecture diagrams, ER diagrams, UML and BPMN flows from natural language or from Terraform, SQL DDL, OpenAPI specs and code repos, with incremental sync and multi-format export. Native export needs the draw.io desktop app.

Uses a strong model to audit your codebase and list evidence-backed issues across correctness, security, performance and testing, writes a plan a cheaper model can execute, and reviews the results. It never edits code itself. By shadcn.

Lets agents run terminal commands on your machine, manage long-running processes, and read, write, search and diff-edit files. Extends the official Filesystem server; collects pseudonymized telemetry by default (no file contents or command arguments), which you can turn off in config.

Tencent's open-source browser bridge: through the bsk CLI and a Chrome/Edge extension, agents use your logged-in accounts in a separate visible window to browse, fill forms and take full-page screenshots, and correlate network requests with console output to debug sites.

Universal psql-style SQL command line: one tool to connect to PostgreSQL, MySQL, SQLite, SQL Server, Oracle and dozens of other SQL and NoSQL databases, with support for copying data between databases.

Open-source research agent: one command runs literature reviews, deep research, paper reviews, paper-code consistency checks and replication plans, searching arXiv, PubMed and more with sources recorded. Good for grad students writing reviews. Run feynman setup to sign in to a model provider.

Open-source Simplified/Traditional Chinese converter: deterministic dictionary-based conversion (no LLM) covering variant characters and regional vocabulary for mainland China, Taiwan and Hong Kong, with limited Japanese kanji support. Runs offline; CLI plus Node.js and Python APIs.

Processes CSV, TSV, JSON and other structured data like awk, sed, cut, join and sort, but by field name, for cleaning, aggregation, format conversion and pretty-printing. The command is mlr; written in Go with no runtime dependencies.

Annotate and review agent-generated plans, docs and code diffs in the browser, then send feedback back to the agent in one click. Hooks into plan mode and supports Claude Code, Codex and other agents. Run the official install script to set up the CLI first.

Linter and formatter for 20+ SQL dialects that auto-fixes most issues and handles Jinja templating and dbt projects (dbt needs a plugin), suited to warehouse code review and CI.

NVIDIA's open-source LLM vulnerability scanner that probes for prompt injection, jailbreaks, data leakage, hallucination and harmful content, supporting OpenAI, Hugging Face, Bedrock and most REST-accessible models. Scanning cloud models needs their API keys.

Answers wage and hour questions for a specific state or country, such as worker classification, overtime, meal and rest breaks, leave and final pay, citing the law for each point and flagging when judgment is needed. US-focused; needs web or a legal database. Lawyer review required. By Anthropic.

Anthropic's official legal plugin marketplace: 13 plugins covering commercial contracts, privacy, product counsel, M&A, employment, regulatory, AI governance, litigation and IP, plus plugins for law school clinics and law students. All output is a draft for attorney review.

Drafts employee policies such as remote work, parental leave and PTO, generates state or country supplements where rules differ, and flags laws in flux. Mostly US states; needs web access for regulations and is best installed with the employment-legal plugin. Lawyer review required. By Anthropic.

Anthropic's official employment law plugin: reviews hiring and termination risk by jurisdiction, classifies workers, tracks leave deadlines, manages internal investigations, and drafts policies with state supplements. Focused on US state law; output needs attorney review.

Pre-termination check for high-risk factors (recent complaints, protected leave, discrimination or retaliation, thin documentation), reviews severance and separation agreements, and looks up state final-pay deadlines. US-focused; needs web or a legal database. Lawyer review required. By Anthropic.

When revising an employee handbook, compares proposed changes clause by clause with the current version, finds knock-on effects (such as PTO changes affecting final pay) and state supplement changes, and flags risks of cutting existing benefits. US-focused; needs legal review. By Anthropic.
