Packages

An MCP server providing read access to Meta/Facebook Ads data including campaigns, ad sets, ads, performance insights, creative assets, and activity history via the Meta Ads API.

Rust port of the Testcontainers library for managing Docker containers in integration tests. Starts real Docker containers (PostgreSQL, Redis, Kafka, etc.) for each test and cleans them up afterward. Allows writing Rust integration tests against real databases and services without mocking. Supports both sync and async (Tokio) test patterns.

Provides globally distributed pub/sub messaging infrastructure with channels, presence tracking, and guaranteed message ordering for real-time applications.

Built-in Rails file attachment system — attaches files to ActiveRecord models and stores them in cloud storage (S3, GCS, Azure Blob) or local disk. Active Storage features: has_one_attached :avatar / has_many_attached :documents in models, form with file_field, direct upload to S3 (bypasses Rails server), image transformation via Vips/ImageMagick (variant), file validation via custom validators or active_storage_validations gem, service configuration in config/storage.yml, background job for variant processing, mirroring between services, and CDN URL generation. Included in Rails since 6.0 with no additional gems required for basic usage.

Declarative resource-based framework for Elixir that generates entire business logic layers from resource definitions. An Ash resource (defresource MyApp.Post do) declares attributes, actions (CRUD + custom), policies, relationships, and calculations. Ash generates CRUD operations, validation, authorization policies, GraphQL (via AshGraphql), JSON:API (via AshJsonApi), and admin UIs (via AshAdmin) automatically. Think Rails scaffold × 10 with declarative policies.

MCP server providing complete macOS desktop automation capabilities including mouse control, keyboard input, screenshot capture, and UI element interaction via Accessibility APIs.

Managed cloud vector database service built on the open-source Chroma engine, offering a REST API and Python/Node SDKs for storing and querying embeddings in agent RAG pipelines.

Automated toolkit for creating, enhancing, and maintaining CLAUDE.md instruction files for Claude Code projects. Includes a skill for analysis/generation, a slash command for interactive enhancement, and a guardian agent for background auto-sync of documentation with codebase changes.

Extends Django to handle WebSockets, long-polling, background tasks, and other async protocols alongside standard HTTP. Django Channels replaces Django's WSGI server with ASGI (via Daphne or Uvicorn), adds channel layers (Redis-backed pub/sub for cross-process communication), and provides WebSocket Consumers (async or sync class-based handlers). Key concepts: Consumer (handles WebSocket connection lifecycle), Channel Layer (Redis pub/sub for broadcasting to groups), Channel Groups (broadcast to all connections in a group). Used for real-time agent status updates, live agent chat interfaces, streaming agent responses to browser, and collaborative agent workspaces.

FastAPI-inspired async Python framework for building message broker microservices. Single unified API for Kafka, RabbitMQ, NATS, and Redis Pub/Sub. Automatic schema generation, built-in testing with TestClient, and type-safe message handling with Pydantic. Dramatically reduces boilerplate for event-driven Python services compared to raw aiokafka or pika.

Frankfurter is a free, open-source, no-API-key-required currency exchange rate API that serves European Central Bank reference rates for 32 currencies with HTTPS and transparent ECB sourcing.

Google Sheets API v4 — read, write, format, and manage Google Sheets spreadsheets programmatically, enabling agents to use Sheets as a lightweight database or reporting surface.

Helicone LLM observability proxy — a drop-in proxy that intercepts LLM API calls (OpenAI, Anthropic, etc.) to log requests/responses, track costs, enable caching, rate limiting, and provide analytics dashboards with minimal code changes.

Email finder and verification API that discovers professional email addresses by domain or name, verifies deliverability, checks for disposable or catch-all configurations, and returns confidence scores. Used for B2B sales prospecting and outreach automation.

Provides a command-line suite and library API for creating, editing, converting, and compositing raster and vector images across 200+ formats including JPEG, PNG, TIFF, WebP, HEIC, PDF, and SVG.

MCP server for Korea's G2B (Government to Business) procurement system — the Nara Market platform for Korean government contracts and procurement. Enables AI agents to search and retrieve Korean government procurement opportunities, contract data, and bidding information.

Original JavaScript monorepo management tool, now maintained by Nx and integrated with Nx task scheduling. Manages multiple npm packages in a single repository — versioning, changelogs, and publishing to npm. Lerna v6+ integrates with Nx for task running and caching. Known for its two versioning modes: fixed (all packages same version) and independent (packages version independently). Still widely used but many teams have migrated to Turborepo or Nx.

LLM-powered PDF and document parsing service from LlamaIndex. LlamaParse converts complex PDFs (multi-column, tables, charts, images) into clean Markdown or structured text optimized for LLM ingestion and RAG. Uses LLMs to understand document structure rather than pure text extraction — producing better table formatting, section hierarchy, and figure descriptions. Designed as the ingestion layer for LlamaIndex RAG pipelines but usable independently.

Provides 132 domain-specific skills (structured documentation with acceptance criteria) for AI coding agents working with Azure services, covering Python, .NET, TypeScript, Java, and Rust SDKs.

Async Python MongoDB driver — the official asyncio-native MongoDB driver for Python, wrapping PyMongo for async/await usage. Motor features: AsyncIOMotorClient, AsyncIOMotorDatabase, AsyncIOMotorCollection, async CRUD (await collection.insert_one(), await collection.find_one()), async aggregation pipeline, change streams with async_for, GridFS async, connection pooling, Tornado support, and full PyMongo feature parity via async interface. Required for FastAPI, aiohttp, and asyncio-based agent backends that use MongoDB.
