Tools

Lets agents operate Home Assistant: control devices, query state and history, create and debug automations and edit dashboards, with 80+ tools. Community-maintained (unofficial); requires your own Home Assistant instance, and running via uvx needs a long-lived access token.

WordPress's official CLI: install and update plugins and themes, manage posts and users, import and export content, run database search-replace and configure multisite from the terminal, without opening wp-admin. Requires PHP 7.2.24 or later.

From Callstack: lets coding agents inspect, operate and verify apps on iOS, Android and HarmonyOS simulators and real devices, reading accessibility snapshots, taking screenshots and recordings, and capturing logs and performance data. Ships both a CLI and a built-in MCP server.

From Callstack: lets coding agents drive and verify iOS, Android, HarmonyOS and desktop apps through accessibility snapshots, with taps, form filling, screenshots, logs and performance sampling, plus a built-in MCP server. Requires Node.js 22.12+.

CLI and TypeScript runtime for discovering and calling MCP servers from the terminal and scripts: list tool signatures and call tools directly, or generate a standalone CLI or typed client from a server. Auto-imports existing MCP configs from Claude Code, Codex and others.

Draws bar charts, histograms, line charts, scatter plots and box plots in the terminal from CSV/TSV on stdin, so you can glance at data distributions at the end of a shell pipeline. The command is uplot.

Design token build tool: define colors, font sizes, spacing and other design specs in one JSON source, then style-dictionary build generates CSS, SCSS, iOS, Android and other platform code, keeping the design system and implementations in sync. Needs Node.js and a config.json.

Read-only mirror of the community plugin marketplace maintained by Anthropic, with 2,000+ community plugins that passed submission review and automated security scans, for Claude Code and Claude Cowork.

Empirical social science skills from Stanford REAP and CoPaper.AI, bundling 77 in-house and third-party collections: topic selection, literature reviews, DID/RD/IV identification, regression tables in Python, Stata or R, robustness audits and paper writing. Stata flows need Stata installed.

Microsoft's official Azure CLI (az) for managing VMs, storage, resource groups and other Azure resources, with JMESPath queries, table or JSON output and clear exit codes for scripting. Run az login first.

Moves files to the trash instead of deleting them, with commands to list, restore and empty trashed files, so anything an agent deletes by mistake can be recovered. Follows the FreeDesktop.org trash spec and shares the trash with GNOME and KDE.

Firebase's official CLI: deploy Hosting, Cloud Functions and security rules, run local emulators, read and write databases and import or export users. The same repo also provides the official Firebase MCP server. Requires a Firebase sign-in.

Lets agents manage Firebase projects: read and write Firestore and Realtime Database, manage Auth users, validate security rules, and check Crashlytics crashes and function logs. Maintained by Firebase; sign in to the Firebase CLI first.

Generates 26+ chart types with AntV, including line, bar, Sankey, word cloud, mind map and pivot table, returning image links. Officially maintained by Ant Group's AntV team; uses a public rendering service by default and can be self-hosted.

Teaches agents to code against the latest Gemini API and Python/TypeScript SDKs: multi-turn chat, function calling, structured output, and image and speech generation, while avoiding deprecated older models. Maintained by Google's Gemini team.

Gemini API development skills: gemini-api-dev (core API and SDKs), gemini-live-api-dev (real-time bidirectional audio/video streaming) and gemini-omni-flash-api (Omni video generation and editing), filling in APIs released after model training cutoffs. Maintained by Google's Gemini team.

Create, read and modify xlsx workbooks without Microsoft Excel installed: formulas, formatting and conditional formatting, charts, pivot tables and tables. Runs locally over stdio or as a remote HTTP service.

Terminal tool for offline IP geolocation and CDN provider lookup, supporting QQwry, GeoIP2, ip2region and other databases. Pipe output from dig, nslookup and similar commands through it to annotate IPs automatically.

From Dagger: gives each coding agent its own container and git branch so multiple agents work in parallel without interfering, with command logs and the ability to take over the terminal at any time. Connects via MCP; needs Docker and Git. Still experimental.

From Dagger: gives every coding agent an isolated container and Git branch so several agents can work in parallel, and you can view command logs, take over the terminal or discard results anytime. Needs Docker and Git locally; still experimental.

Open-source marketing plugin with 48 skills: SEO and AI search optimization (GEO), GA4 and Search Console analysis, ad diagnostics for Google, Meta, X, LinkedIn, Reddit and TikTok, and WordPress upkeep. Some SEO skills need only a URL; live data requires NotFair OAuth and linked accounts.

Fast async link checker written in Rust that scans websites and Markdown, HTML and other files for broken links and email addresses, with JSON output, config files and an official GitHub Action, often wired into docs CI.

Knownsec's open-source Python-use agent: describe a task in plain language and it writes and runs Python on your machine, e.g. tidying Excel files, summarizing attendance or screening resumes. Needs Python 3.11+ and a model API key such as DeepSeek; code runs locally, so back up important files.

Guides SwiftUI view building: choosing @State, @Binding, @Observable or @Environment by ownership, wiring TabView, NavigationStack and sheets, async loading with .task, small composed views and previews, plus anti-patterns and a component reference index.
