Build JavaScript and TypeScript apps with Bun, an all-in-one toolchain that replaces Node.js, npm, a bundler, and a test runner with one fast binary that executes TypeScript directly.

Figma MCP bridge that connects Claude Code, Cursor, and other agents to a Figma plugin through WebSocket channels so they can read designs and modify nodes, text, layouts, styles, annotations, and components.

MCP server that gives Claude and other MCP clients structured access to n8n node documentation, workflow templates, validation tools, and optional n8n API workflow management.

Source-backed Claude agent prompt for contributing to the official storybookjs/storybook monorepo using its AGENTS.md guidance for the next branch, Node 22.12+, Yarn Berry, NX, yarn task, Storybook Vitest, sandboxes, framework packages, docs, and generated-file safety.

Next.js App Router production-architecture specialist focused on the server/client boundary, the explicit caching model, route handlers, and Node-vs-Edge runtime tradeoffs — decisions, not component tips

Aggregate Markdown folders into cohesive knowledge bases with automated table of contents generation, cross-link validation and rewriting, heading normalization, and multi-format export (HTML, PDF, DOCX, EPUB).

Explore and script against REST APIs with comprehensive authentication support (API keys, OAuth 2.0, JWT Bearer tokens, Basic Auth), pagination utilities (cursor-based, offset-based, page-based), retry logic with exponential backoff and jitter, error handling for HTTP status codes, rate limiting with Retry-After hea...

The official Codacy MCP server (@codacy/codacy-mcp) that gives AI assistants access to the Codacy API for code quality, security, and coverage — listing repository and pull-request issues, retrieving file coverage and duplication, searching security (SRM) findings, inspecting analysis tools and patterns, and running local analysis with the Codacy CLI.

The official Convex MCP server, built into the Convex CLI, that lets AI agents introspect and query a Convex deployment — listing tables, paginating data, running deployed functions and read-only one-off queries, reading logs and function specs, and managing environment variables — with production deployments blocked by default as a safety measure.

The official Infisical MCP server (@infisical/mcp) that lets AI assistants work with Infisical's secrets-management API through function calling — reading, creating, updating, and deleting secrets, and managing projects, environments, folders, and project members — authenticating with a Machine Identity (universal auth) or an access token against Infisical Cloud or a self-hosted instance.

The official InfluxData MCP server for InfluxDB 3 (Core, Enterprise, Cloud Dedicated, Clustered, and Cloud Serverless). It lets LLMs run SQL queries, write line-protocol data, inspect databases and measurement schemas, manage databases and tokens, and check cluster health over the Model Context Protocol.

The official Mux MCP server (@mux/mcp) that gives AI agents access to the Mux API for video and analytics. It uses a "Code Mode" scheme — exposing a documentation-search tool and a code tool that runs agent-written TypeScript against the Mux SDK in an isolated sandbox — to work with Mux Video (assets, live streams, playback IDs, uploads) and Mux Data (viewer metrics and monitoring).

The official Paddle MCP server (@paddle/paddle-mcp) that lets AI assistants work with Paddle Billing — managing the product catalog, prices, and discounts, customers and businesses, subscriptions, transactions and adjustments, and financial reports — over the Paddle API, with sandbox or production environments and a read-only / non-destructive / all tool-permission filter.

The official Telnyx MCP server (@telnyx/mcp) that lets AI assistants use Telnyx's communications APIs through function calling — messaging (SMS/MMS), voice and call control, phone-number management, SIP connections, verification, and wireless. The npx package proxies to Telnyx's hosted MCP server over HTTPS and authenticates with a Telnyx API key.

The official Tigris MCP server (@tigrisdata/tigris-mcp-server) that connects AI agents to Tigris, a high-performance S3-compatible object storage system — listing, creating, and deleting buckets; listing, uploading, and deleting objects; creating folders and files; and generating shareable links — using S3-style access keys against the Tigris endpoint.

The official Xero MCP server (@xeroapi/xero-mcp-server) that lets AI assistants work with a Xero accounting organisation — managing contacts, chart of accounts, invoices, credit notes, payments, bank transactions, manual journals, quotes, items, and payroll, and reading financial reports — using Xero OAuth2 custom connections or a bearer token.

Claude Code statusline that uses simple-git status data to show dirty worktree risk, staged changes, untracked files, and merge conflicts.

Official TypeScript SDK for Model Context Protocol clients and servers, with the production v1 `@modelcontextprotocol/sdk` package, active v2 server and client package work, Node.js, Bun, and Deno support, transports, OAuth helpers, tools, resources, prompts, examples, and API documentation.

Compile Rust, C++, or Go to WebAssembly and run it in the browser, Node.js, and serverless runtimes: wasm-bindgen JS interop, WASI for system access, the Component Model, and SIMD.

MCP server for controlling Adobe After Effects through a local Node bridge and ScriptUI panel for compositions, layers, keyframes, expressions, masks, and effects.

MCP server that lets Claude install other MCP servers into Claude Desktop by writing MCP config entries for npm packages, uvx packages, or locally cloned Node-based MCP server projects.

Unity Editor MCP bridge from CoderGamester that lets Claude and other MCP clients inspect scenes, manage GameObjects, edit components and materials, run tests, read console logs, and automate Unity project workflows through a Node.js stdio server connected to a Unity WebSocket bridge.

Build and review Hono TypeScript APIs for Cloudflare Workers, Bun, Deno, Node.js, Vercel, Netlify, and other Web Standards runtimes with routing, middleware, validation, RPC clients, OpenAPI generation, deployment checks, and production safety review.

MIT-licensed DataFrame query engine written in Rust for Python, Rust, Node.js, R, and SQL workflows with lazy execution, streaming, Arrow integration, and file, database, and cloud I/O.

Complete Claude Code WSL2 installation tutorial in 30 minutes. Configure Node.js, resolve PATH conflicts, and optimize Windows development performance.

A Stop hook that runs npm audit, pip-audit, safety, or bundler-audit automatically at the end of every Claude Code session, detecting CVEs and outdated packages across Node.js, Python, and Ruby projects.

PostToolUse hook that detects writes to migration, schema, and SQL files then runs framework-specific status checks — runs knex migrate:status for Node.js projects and python manage.py showmigrations for Django projects.

Add PostHog to a Next.js app with client and server event capture, user identification, feature flags, session replay privacy controls, reverse-proxy planning, and production analytics validation.
