Tools

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.

200+ skills for brand growth: customer and competitor research, ad and social performance analysis, ad creatives and social content, SEO, lead mining and outreach. Most are free; skills that pull external data use GooseWorks account credits (1,000 on sign-up), and some need keys like Apify.

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+.

Drives a local ClipForge (open source) to turn product images, links or a one-line topic into vertical short videos with script, footage, voiceover, captions and music, plus a QA pass. Self-host it with Node.js and FFmpeg; scripts need an LLM (Ollama works); AI visuals need a paid key.

The standard machine translation scorer: computes BLEU, chrF and TER with significance tests and downloads public test sets such as WMT, to compare engines or prompts. Needs Python 3.9+ and reference translations; automatic metrics are a rough screen, so final copy still needs human review.

Pre-submission review for CS conference papers (CVPR, ACL, NeurIPS and more): polish, translate or condense on request, or let AI reviewers raise issues and a jury rule on them. Only wording fixes are drafted, with your approval; missing experiments go back to you, never invented. Needs Node.js.

Creates and edits local CapCut (JianYing) drafts from the terminal: rough cuts on silence, styled subtitles and multilingual versions, still editable track by track in CapCut. Needs Node 18+ and desktop CapCut; subtitles need Whisper, translation an Anthropic key. No encrypted drafts. Unofficial.

Skills Sentry's engineering team uses itself: code review, bug finding, security review, writing commits and PRs, and iterating on a PR until CI passes. Maintained by Sentry; some skills follow its internal conventions.

Lets agents query Google Ads accounts, campaigns and performance data with GAQL; currently read-only tools only. Maintained by Google; needs Google Cloud credentials and Google Ads API access.

Salesforce's official skill that sets up Service Cloud Omni-Channel routing from the CLI instead of Setup clicks: agent and supervisor users, queues, presence statuses, permissions and routing flows. Read-only preview; writes only to sandbox, trial or dev orgs. Needs Service Cloud, sf and jq.

Salesforce's official plugin that helps service admins configure Service Cloud web chat, messaging, WhatsApp and Email-to-Case channels, connect Agentforce service agents to them and set up handoff to humans. Needs Salesforce org admin rights, a logged-in Salesforce CLI (sf) and Python.

Alibaba Cloud's official CLI (aliyun): manage ECS, OSS and other services through OpenAPI, with structured output, JMESPath filtering, waiting on resource states, product plugins and a built-in MCP proxy. Configure credentials first; OAuth sign-in works locally.

Turns ComfyUI workflows into MCP tools with no code, covering generation and conversion across text, image, speech and video; works with local ComfyUI or RunningHub in the cloud. Start the server with uvx pixelle and configure an LLM first.

A large skill library for non-engineering teams: 372 skills covering project management, marketing, executive advisory, legal (NDA triage, contract review, privacy, DPIAs), SOC 2 and GDPR compliance, HR and finance. Add it from the Claude desktop plugin page. Have legal output reviewed.

HR operations plugin bundling four skills: recruiting (job descriptions, interview scorecards, funnel analysis), HRBP (talent planning, performance, employee relations), people analytics (attrition prediction, pay equity) and ops, with helper Python tools. Scripts need Python 3.

Open-source library of 170+ marketing and SEO skills: technical SEO, keyword and competitor research, content, email and community, platform ads, launches, pricing and traffic analysis. Install a few per task and supply your product details; Search Console and ad analysis need those accounts.

Turns product info, packaging and reference images into a visual plan designers or image models can execute: per-image layouts for main images, detail pages, listings and A+ content, in-image copy and prompts. Keeps an evidence log and checks ad-law risk; covers Amazon, Taobao, JD and more.

Microsoft's official Microsoft 365 MCP: query your email, meetings, OneDrive and SharePoint files, Teams messages and colleagues in plain language, e.g. tomorrow's meetings or someone's budget emails. Needs a Microsoft 365 Copilot license, tenant admin consent and Node.js 18+; public preview.

ComfyUI's official CLI: install and launch ComfyUI in one step, manage custom nodes and model downloads, and run image and video workflows, with --json output on every command for agents. Can also submit jobs to paid Comfy Cloud.

Sentry's official CLI: upload source maps and debug symbols, manage releases, and view issues and logs. Needs a Sentry account or self-hosted instance; a newer official CLI is replacing it, so this repo mainly gets bug fixes.

ChatCut's official plugin: edit ChatCut video projects by chat from Claude Code or Codex: import media, adjust the timeline, transcribe and caption, generate voiceover, music and motion graphics, and export. Needs a ChatCut account (free tier available); sign in via browser on first use.

Lets agents read and write Google Sheets: list and search spreadsheets, read and batch-update cells, insert rows and columns, create and share sheets and build charts, with the option to enable only some tools to save context. Needs a Google Cloud service account or OAuth credentials.

Graph database MCP server from Neo4j Labs: reads the graph schema and runs read and write Cypher queries, with read-only mode, query timeouts and response token limits. Needs a Neo4j instance with the APOC plugin enabled.
