Tools

Third-party LSP plugin marketplace with 30+ language server plugins, including TypeScript, Python, Rust, Go, Java, C/C++, Vue, Svelte, Elixir and Haskell, covering more languages than the official set. Requires Claude Code 2.1.50+; install the language servers yourself.

Appium's official MCP server: lets agents start sessions on Android and iOS emulators and real devices, locate elements, tap, type and take screenshots, and generate Java/TestNG test code. Needs the Android SDK or Xcode.

Official Firebase skills: CLI and project setup, Authentication, Firestore, Hosting and App Hosting, Data Connect, Remote Config, Crashlytics, AI Logic, and writing and auditing security rules. Most use the Firebase CLI and need a Firebase project.

Official Firebase skill: install and sign in to the Firebase CLI, create and switch projects, download app config files such as google-services.json, and set up the other Firebase skills for Auth, Firestore, Hosting and more.

Develops an original visual language for a brand, campaign, publication, site or product. Without looking at contemporary design, it builds ten typography-only HTML directions; once you lock one, it turns it into a production system. Not for routine UI fixes or existing design systems.

Official Tavily skills: let agents search the web, extract page content, discover site URLs, crawl in bulk and run cited deep research through the Tavily CLI (tvly). Install the CLI first; search and extract have a limited no-login tier, other features need sign-in or an API key.

Design token CLI (formerly Cobalt UI): reads W3C DTCG tokens for color, type, spacing and more, validates them and generates CSS, Sass, JS/TS, Swift, Tailwind and other code via plugins. Runs in CI so design specs flow into code automatically. Needs a Node.js project.

Lets agents work with Salesforce orgs authorized on your machine: SOQL queries, metadata deploy and retrieve, Apex test runs and permission set assignment, plus toolsets for LWC development. Maintained by Salesforce; authorize your org with the Salesforce CLI first.

Astronomer's official data engineering plugin: write Airflow DAGs to best practices, debug pipeline failures, trace data lineage, profile warehouse tables and migrate from Airflow 2 to 3, with a built-in Airflow MCP server and session hooks.

Research guardrails for PhD students: reproduce arXiv papers, debug training anomalies with evidence, compare runs at matched epochs, check paper-code consistency, verify BibTeX, find literature gaps and predict reviewer comments. No MCP or extra dependencies; mostly for ML research.

Design engineering skill that steers agents away from generic AI-looking UI when building dashboards and landing pages, reviews interfaces for usability and adds motion and polish. npx installs the skill only; slash commands, MCP quality gates and review agents need the CLI or plugin.

Deploys HTML or full-stack projects generated by agents to Tencent Cloud EdgeOne Makers and returns a public URL; supports both the international and China sites. Maintained by Tencent Cloud EdgeOne (formerly EdgeOne Pages MCP); sign in via browser or set an API token.

Browser automation MCP built on Selenium WebDriver for Chrome, Firefox, Edge and Safari: locate elements, click and type, upload files, take screenshots, run scripts, and handle alerts and cookies. A good fit for test teams already using Selenium.

Official FinLab quant skill: lets agents use FinLab data (mainly Taiwan stocks, plus US, Japan, Korea and Hong Kong) to write stock-picking strategies, run backtests and analyze factors. Needs a FinLab account (free tier has a daily data cap), Python 3.10+ and uv. Not investment advice.

Makes a product film (landing-page loop, launch video, promo, demo reel) in code with Remotion, reusing the product's own design system, components and voice. It interviews the user first, then writes the story, syncs scenes to music beats, reviews stills in loops and verifies the final render.

Applies a Scandinavian visual system: black-and-white neutrals with alpha ink for hierarchy, restrained sans-serif type, generous spacing, clear page chapters and minimal decoration, without sacrificing clarity or accessibility. Has apply, review, prototype and deep modes; manual invoke only.

Lets agents run local ComfyUI workflows to generate images, audio and video, regenerate from earlier results with new parameters, check the queue and switch models. Install and start ComfyUI, then clone this repo and run the server with Python (port 9000 by default).

Connects to self-hosted or managed Nextcloud so agents can manage files, calendars, contacts, notes, Deck boards and mail, and read PDF and Word content (OCR for scans is opt-in); suits teams that value data ownership. Needs a Nextcloud account with an app password, and uv.

Hands Figma node layout, styles and images to AI coding tools to turn into high-fidelity HTML/CSS, React or Tailwind code, and downloads design images locally. Needs a Figma personal access token; sends basic usage stats; switch to the plugin version if you hit Figma API rate limits.

Official Databricks plugin with skills for the CLI and auth, Genie data queries, Apps, Lakebase, Lakeflow jobs and pipelines, Model Serving and DABs deployment, plus hooks for prompt routing, session context and auth failure hints. Needs a Databricks account.

Official Databricks skills guiding agents to build Lakeflow pipelines and jobs, Apps, Lakebase, Vector Search, Model Serving and AI/BI dashboards on the lakehouse. Needs the Databricks CLI.

Official testing skills from TestMu AI (formerly LambdaTest) covering 40+ frameworks including Selenium, Playwright, Cypress, Appium, pytest and JUnit, guiding agents to write unit, end-to-end and mobile tests. Runs locally; cloud cross-browser and real-device runs need an account.

Mapbox's official MCP: geocoding, POI search, driving, walking and cycling directions, travel-time matrices, multi-stop route optimization, isochrones and map rendering, plus offline distance and area calculations. Needs a Mapbox access token; an official hosted endpoint is available.

Apache Doris's official MCP: gives agents read-only access to explore table metadata, run and explain SQL, diagnose slow queries, and check cluster status, load jobs and data governance info. Needs Python 3.12+ and Doris 2.0 or later.
