Packages

Cross-platform Python library for accessing system and process information. psutil provides CPU usage, memory stats, disk I/O, network connections, and process management (list, kill, inspect) through a unified Python API that works on Linux, macOS, and Windows. Used in monitoring agents, resource-aware task schedulers, and system health checks.

Configuration management library for Python using Pydantic models. pydantic-settings loads configuration from environment variables, .env files, AWS Secrets Manager, Azure Key Vault, and other sources — automatically parsing and validating values with Pydantic's type system. Define a Settings class once and get type-safe configuration with validation, documentation, and source priority out of the box. The standard for 12-factor Python applications.

Data parallelism library for Rust. Converts sequential iterators to parallel with a single `.par_iter()` call. Uses a work-stealing thread pool to automatically distribute work across all CPU cores. The simplest way to achieve CPU parallelism in Rust — no manual thread management, no locks, no unsafe code.

MCP server for xAI's Grok models — the frontier LLMs from Elon Musk's AI company. Grok models offer real-time knowledge (via X/Twitter data), long context windows, and competitive frontier model capabilities. OpenAI-compatible API enables easy integration. Enables AI agents to call Grok-1.5, Grok-2, and future Grok models.

Ansible Automation Platform (AAP) MCP server enabling AI agents to interact with Red Hat's enterprise automation platform — launching playbook templates, monitoring job status, querying inventory, managing credentials, and integrating Ansible Tower/AAP's automation workflows into agent-driven infrastructure automation and DevOps pipelines.

MCP server plugin for Cocos Creator 3.8+ that enables AI assistants to control the game editor through 50 integrated tools covering scene operations, node management, component handling, prefab system, project builds, debug tools, asset management, and scene view control. Implements 99% of editor functionality via standardized MCP protocol over HTTP.

Low-level JavaScript library for positioning floating elements (tooltips, popovers, dropdowns, menus) relative to anchor elements. Handles collision detection, overflow prevention, placement flipping, and arrow positioning. Framework-agnostic core with React, Vue, and React Native adapters. Successor to Popper.js — more modern API, better TypeScript support, smaller bundle. Used internally by Radix UI, Headless UI, and many UI libraries.

JavaScript utility library providing 300+ functions for arrays, objects, strings, numbers, and functional programming. Deep cloning, debounce/throttle, groupBy, merge, pick, omit, chunk, flatten, and hundreds more. One of the most downloaded npm packages ever. 'The Swiss Army knife of JavaScript' — fills gaps in native JavaScript APIs with consistent, well-tested utility functions. Lodash/fp variant provides auto-curried, immutable versions of all functions.

Full-featured React component library and hooks collection. Mantine ships 100+ components (Button, Modal, DataTable, DatePicker, RichTextEditor, etc.) and 50+ hooks (useForm, useLocalStorage, useMediaQuery, etc.). Unlike Radix UI which is unstyled primitives, Mantine provides fully styled components with a complete design system, dark mode, theming API, and form utilities. Well-regarded for quality, documentation, and active maintenance.

Modular RAG MCP server providing a flexible, composable Retrieval-Augmented Generation system for AI agents — supporting multiple vector stores (Chroma, Pinecone, etc.), embedding models, and retrieval strategies, enabling agents to query and maintain knowledge bases with configurable RAG pipeline components.

Elegant terminal spinner library for Node.js CLI applications. Displays animated loading spinners with text in the terminal during async operations. Supports multiple spinner styles (dots, line, arc, etc.), success/failure/warning state changes with icons, persistent lines, and concurrent spinner management with ora.all(). Ora v8+ is ESM-only. The go-to library for CLI UX feedback in Node.js tools like deployment scripts, build tools, and agent CLIs.

MCP server for querying Oracle Cloud Infrastructure (OCI) pricing data. Enables AI agents to retrieve OCI service pricing, compare costs across regions and SKUs, estimate workload costs, and support FinOps workflows for Oracle Cloud environments.

Collection of essential Vue Composition API utilities (composables). 200+ functions covering sensors (useMousePosition, useResizeObserver), state (useLocalStorage, useSessionStorage), browser APIs (useClipboard, useWebSocket, useNotification), and more. The Vue 3 equivalent of React's custom hooks ecosystem — eliminates the need to write common composable utilities from scratch.

Comprehensive JavaScript date utility library with a functional programming approach. Unlike Day.js/Moment.js (object-oriented), date-fns exports 200+ pure functions that work with native JavaScript Date objects. Each function is independently importable — perfect tree-shaking. Functions like format(), addDays(), differenceInCalendarDays(), isAfter(), startOfWeek() cover everything date manipulation needs. Called 'Lodash for dates'.

MCP server for experimental small-scale engineering agents with multi-provider LLM support (OpenAI GPT-5, Anthropic Claude, Ollama local models). Implements a nested two-layer agent system where an outer MCP client spawns inner autonomous agents that can perform file system operations. Includes CLI, benchmarking, and HOP/LOP evaluation patterns for systematic multi-model testing.

MCP server enabling AI agents to interact with pfSense firewall and routing appliances — querying firewall rules, monitoring network traffic, checking VPN status, reading system logs, managing firewall rules, and controlling network infrastructure through pfSense's management API. Enables AI-driven network security monitoring and operations.

Clever REST API for K-12 EdTech single sign-on (SSO) and rostering platform. Enables AI agents to retrieve rostered student, teacher, and section data synced from district SIS systems, handle SSO authentication flows for EdTech applications, access district and school hierarchy data, retrieve course and class assignments, manage student-teacher-section relationships, integrate with PowerSchool, Infinite Campus, and other SIS platforms, and connect EdTech applications to district identity infrastructure.

Deprecation decorator for Python functions and classes — emits DeprecationWarning or other warnings when deprecated code is called. deprecated features: @deprecated decorator for functions/methods/classes, reason= parameter for migration instructions, version= parameter for when deprecation was introduced, action= parameter for warning category (always/once/default/error/ignore), category= for custom warning class, @deprecated.classic.deprecated for simpler API, wrapt-based transparent wrapping that preserves function signatures, and __deprecated__ attribute for deprecation metadata.

Miro is an online collaborative whiteboard platform. Its REST API v2 enables agents to create and manage boards, add visual items (sticky notes, shapes, connectors, images, text, cards, frames), and automate whiteboard content. WebSocket support enables real-time board updates.

OpenGuardrails MCP server enabling AI agents to apply safety guardrails — validating agent outputs for harmful content, checking responses against configurable safety policies, enforcing content restrictions, and integrating AI safety controls into agent-driven applications requiring responsible AI guardrails.
