Packages

Natural language scripting framework where you write AI workflows in .gpt files using plain English, and GPTScript executes them by calling LLMs, tools, and external APIs.

Google Cloud Run API — deploy and manage containerized services that scale to zero, with automatic HTTPS, traffic splitting, and pay-per-use pricing.

Google Cloud Tasks managed async task queue — enqueue HTTP tasks or App Engine tasks with configurable retry, rate limiting, deduplication, and scheduled dispatch.

HackerRank REST API for technical skills assessment and developer hiring platform. Enables AI agents to create and manage coding tests, invite candidates, retrieve assessment scores and code submissions, track hiring funnel progress, and integrate technical screening into ATS workflows. HackerRank is widely used for technical hiring screening across the software industry.

Cloud cost estimation tool for Terraform, OpenTofu, Pulumi, and CloudFormation. Infracost analyzes IaC code and shows the cost impact of changes before deployment — posting a cost diff comment on PRs showing what infrastructure changes will cost. Supports all major cloud providers (AWS, GCP, Azure) with a public pricing API and a CI/CD integration layer for Atlantis, GitHub Actions, GitLab, and more.

Terminal UI for Kubernetes — interactive ncurses-style dashboard for managing and monitoring Kubernetes clusters. K9s features: real-time pod listing with status and restarts, log streaming (l key), exec into pods (s key for shell), port-forward (shift-f), describe resources (d key), delete resources (ctrl-d), namespace switching, resource filtering (/pattern), custom views via plugins, pulses view for resource changes, xray for dependency tree, and skin themes. Replaces repetitive kubectl commands with interactive navigation. Works with any kubectl-accessible cluster (minikube, EKS, GKE, AKS).

Modern Apache Kafka client for Node.js written from scratch in JavaScript (no librdkafka dependency). Supports producer/consumer groups, transactions, schema registry integration, admin client for topic management, and TypeScript types. The most popular Kafka client for Node.js agent event streaming pipelines.

AI-powered test generation and record-replay testing tool. Keploy captures real API traffic and automatically generates integration tests + mocks/stubs from captured traffic. Uses eBPF for network-level traffic capture (no code changes needed). When re-run, Keploy replays the captured API calls against your application and mocks external dependencies. Designed to dramatically reduce the effort of writing integration tests for backend services.

TypeScript-native headless CMS with code-first schema definition, built-in REST and GraphQL APIs, and deep Next.js App Router integration for full-stack content management.

A framework (Python and JavaScript) for building full-featured Slack apps that handle events, slash commands, interactive components, and workflows using a middleware pipeline with both HTTP and Socket Mode transport.

Statsig's REST API and SDKs for managing feature gates, dynamic configs, experiments, and layers — with built-in metrics and statistical analysis for measuring feature impact.

Open-source tool that queries cloud infrastructure, SaaS APIs, and security tools using SQL. Steampipe translates SQL queries into API calls across 140+ plugins (AWS, Azure, GCP, GitHub, Kubernetes, Slack, Okta, etc.), enabling unified infrastructure querying. Steampipe Cloud provides a REST API for running queries and benchmarks remotely. Used for cloud security auditing, asset inventory, and compliance checking via SQL.

Supabase Storage REST API — S3-compatible object storage with Postgres RLS-based access control, enabling agents to upload, retrieve, and manage files in buckets with fine-grained per-row access policies, built-in CDN, and on-the-fly image transformation.

PostgreSQL extension for time-series data that adds automatic partitioning (hypertables), continuous aggregations, and compression while preserving full SQL compatibility and the PostgreSQL ecosystem.

Serverless Kafka-compatible message streaming service with a REST API optimized for edge and serverless environments — pay-per-message pricing with zero cluster management and HTTP-based produce/consume for environments where native Kafka TCP connections are not available.

High-performance reactive database for React Native and web apps. WatermelonDB uses SQLite (native) or IndexedDB (web) for local storage with a reactive observation system that automatically re-renders components when data changes. Designed for 'lazy loading' — queries run lazily and only fetch data when observed. The sync engine enables server synchronization with a push/pull protocol that your server implements. Used by Nozbe (productivity apps) in production with tens of thousands of records.

A standardized framework for recording browser user interactions via a Chrome extension and replaying them either exactly or as AI-condensed smart sequences, with the ability to convert recordings into reusable MCP servers for AI agent consumption.

Serverless PostgreSQL-compatible database with built-in full-text search powered by Elasticsearch and native AI/vector search features, accessible via REST API and TypeScript SDK.

Web indexing and search tool that crawls websites, generates vector embeddings, and exposes crawled content through an MCP server and REST API for LLM agents.

Official ElevenLabs MCP server enabling AI assistants to generate speech, clone voices, transcribe audio, isolate voices, and create soundscapes through the ElevenLabs API.
