Yahoo Finance (yfinance) MCP server enabling AI agents to access financial market data — retrieving stock prices and historical OHLCV data, fetching company fundamentals and financials, querying earnings and dividends, accessing ETF and mutual fund data, and integrating free financial market data into agent-driven investment research and financial analysis workflows.

Toolkit is a platform for creating AI agent tools, allowing users to generate MCP servers from API documentation and build custom skills for Claude Code.

Local-first MCP server for Meta Ads automation and reporting workflows.

Native C++ bcrypt password hashing library for Node.js. Wraps the native bcrypt implementation via node-gyp for maximum performance. Provides async (bcrypt.hash/bcrypt.compare) and sync (bcrypt.hashSync/bcrypt.compareSync) APIs with configurable cost factor (salt rounds). The native C++ implementation is faster than the pure JavaScript bcryptjs alternative. The standard choice for password hashing in Node.js applications requiring maximum performance.

Express.js middleware that parses Cookie headers and populates req.cookies with an object of cookie name-value pairs. Supports signed cookies (HMAC-SHA256 via a secret) with req.signedCookies for tamper detection. Part of the expressjs GitHub organization. The standard way to read cookies in Express applications — used alongside express-session or directly for stateless cookie-based auth.

Tailwind CSS component library that adds semantic class names on top of Tailwind utilities. Instead of writing 15 Tailwind classes, use class='btn btn-primary' for a styled button. Includes 56+ components and 30+ built-in themes (dark, light, dracula, cyberpunk, etc.). No JavaScript — pure CSS with Tailwind as the engine. The most popular Tailwind CSS component library by GitHub stars.

A WordPress plugin that extends the WordPress MCP Adapter to expose Elementor data, widgets, and page design tools as MCP tools, enabling AI agents to create and manipulate Elementor page designs programmatically.

Environment variable validation library for Node.js. envalid validates and transforms process.env variables at startup — defining required variables, optional variables with defaults, type coercion (str, num, bool, url, email, port), and custom validators. Throws descriptive errors at startup if required variables are missing rather than silently failing at runtime. Essential for 12-factor app configuration.

A hosted version of the Everything server for demonstration and testing purposes, implementing the Model Context Protocol (MCP) with OAuth 2.0 authentication.

FastMCP File Server is a secure file server implementing the Model Context Protocol (MCP) that provides AI assistants with safe file operations, including comprehensive file management and multi-tier authentication.

A Model Context Protocol (MCP) server that provides seamless, standardized access to Fast Healthcare Interoperability Resources (FHIR) data from any compatible FHIR server. Designed for easy integration with AI tools, developer workflows, and healthcare applications, it enables natural language and programmatic search, retrieval, and analysis of clinical data.

A Model Context Protocol (MCP) server that provides authenticated access to Google Workspace APIs, offering integrated Authentication, Gmail, Calendar, and Drive functionality.

MCP server that provides AI access to Logseq and Obsidian knowledge graphs, enabling navigation, search, analysis, writing, and decision-making tools.

Kotlin code formatter and linter from Pinterest — zero-configuration (no .editorconfig required for defaults) formatter that enforces the Kotlin official style guide. ktlint provides: auto-formatting (ktlint --format), lint checking (ktlint check), Gradle integration (ktlintCheck/ktlintFormat tasks), IntelliJ/Android Studio plugin, and EditorConfig support for custom rules. Works as a complementary tool to Detekt — ktlint handles formatting (indentation, spaces, blank lines, trailing whitespace) while Detekt handles code smells and complexity. Part of most Android/Kotlin CI pipelines.
