Tools

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.

Supabase's official CLI: runs the full backend stack locally (Postgres, Auth, Storage, Edge Functions), manages database migrations, generates types and deploys functions. The local stack requires Docker.

Terraform and OpenTofu best practices from Anton Babenko: diagnoses the failure mode first, then guides testing, module structure, state management, CI/CD and security scanning. Works for AWS, Azure and GCP.

Uses hooks to enforce test-driven development in Claude Code: blocks implementation without a failing test, prevents code beyond what tests require, and can use lint results to push refactoring. Needs Node.js 22+. Still maintained, but the author suggests its successor Probity for new projects.

Lets Claude Code and other agents call Antigravity CLI or Gemini CLI, using Gemini's large context window to analyze big files and whole codebases; with Gemini CLI it can also test code in a sandbox. Install and sign in to the CLI first. Not an official Google project.

WordPress's official skill collection: block development, block themes, plugin architecture, REST API, Interactivity API, WP-CLI, performance profiling and Playground, so agents write code to modern WordPress standards and avoid common security pitfalls.

Draws a code change or part of a codebase as an animated architecture or data-flow diagram. The agent writes a JSON graph, validates and renders it to SVG with the PR Lens CLI, then pushes it to a prlens.dev canvas or attaches it to a GitHub, GitLab or Bitbucket pull request.

Explains a codebase, feature, command or pull request to someone new to it as a PR Lens canvas: one plain sentence first, then a walkthrough that grows the diagram from two boxes to the whole picture, delivered as a shareable link. Requires the PR Lens skill and its npx CLI.

Stripe's official CLI: forward and trigger webhook events locally, tail API request logs in real time, and create, read, update or delete Stripe objects to debug payment integrations. Needs a Stripe account; run stripe login first.

App Store Optimization and app marketing skills: keyword research, title and description optimization, competitor tracking, review management, launch and ad planning. Works from general knowledge alone; add an Appeeky API key or MCP for real App Store data (free accounts get 100 credits a month).

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 native Go MCP server for Kubernetes and OpenShift: talks to the API server directly to create, read, update and delete any resource, view pod logs, exec commands and install Helm charts, without needing kubectl. Supports multiple clusters.

Translation management for Ruby/Rails: statically analyzes code to find missing and unused keys, normalizes locale files, fills gaps via Google Translate, DeepL or OpenAI, and exports CSV for translators. Requires the i18n gem (Rails default) and Bundler; machine translation needs an API key.

The Linux Foundation's open-source compliance toolchain: analyzes project dependencies, scans licenses and copyrights, checks known vulnerabilities, flags policy violations and generates SBOMs and notice files. Needs Java 25 or Docker and ideally 8 GB RAM; have legal review license findings.

The HR department of headcount's company-style agent org: 12 skills for org design, hiring, pay and levels, performance, employee relations, compliance, benefits and leave, on/offboarding, payroll, workforce planning and training. No account needed; have HR or a lawyer check compliance.

The legal and risk department of headcount's company-style agent org: 8 skills for contracts and negotiation, governance, disputes and evidence, IP, privacy, compliance and a risk register; can vet other departments' work. Skills only, no account; laws vary by region, so have a lawyer review.

Unofficial Freshservice CLI built with Printing Press: lets AI check an IT agent's queue, flag tickets near SLA breach, search tickets and the knowledge base, gauge team workload, spot recurring issues and KB gaps, and manage changes and assets. Needs a Freshservice account and API key.

Microsoft's official Azure DevOps MCP server: query and act on work items, repos, pull requests, build pipelines, test plans and wikis. Sign in with a Microsoft account that has access on first use; Microsoft recommends the no-install remote version instead.

Community-maintained GitLab MCP server: manage projects, merge requests, issues, pipelines, wikis and releases, with support for self-hosted instances and a read-only mode. Needs a GitLab personal access token or OAuth.

Self-hostable long-term memory for agents, offering MCP, a REST API and a web dashboard: semantic search, knowledge graph and automatic memory consolidation. Embeddings are computed locally; choose SQLite, Cloudflare or Milvus as the backend.

Stripe's official plugin: bundles the remote Stripe MCP with skills for integration best practices, Connect, Stripe Apps and API upgrades, plus commands that explain errors and list test card numbers. Available in the official Claude and Codex marketplaces.

Guides Stripe integration decisions: Checkout vs PaymentIntents, Connect, subscription billing, tax, webhooks and key security, and steers away from deprecated APIs. Maintained by Stripe.

Stripe's official skill collection: payment integration best practices, SDK and API version upgrades, Connect platform onboarding and docs lookup, with content synced automatically from the Stripe docs.

Searches and reads official Microsoft Learn documentation and code samples for Azure, .NET and more, so agents give fewer outdated answers about Microsoft tech. Maintained by Microsoft; the remote server is free and needs no key.
