Packages

MotherDuck managed cloud DuckDB — run DuckDB analytical queries in the cloud with shared databases, collaboration, and hybrid local+cloud execution via the DuckDB client.

MCP server that exposes thousands of Apify Actors (pre-built web scrapers and automation tools) to AI assistants, enabling structured data extraction from social media, search engines, e-commerce sites, and more.

Official Microsoft Learn MCP server providing AI agents with access to the full Microsoft documentation corpus — Azure, .NET, Microsoft 365, Visual Studio, and thousands of Microsoft technical docs.

ATLAS (Adaptive Task and Logic Automation System) MCP server enabling AI agents to manage projects and tasks hierarchically — creating and organizing project trees, tracking tasks with dependencies, storing research notes and knowledge, and integrating structured project management into agent-driven development and planning workflows.

Official Cloudflare Workers MCP server enabling AI agents to interact with Cloudflare's developer platform — deploying and managing Workers functions, configuring Cloudflare services (DNS, CDN, security rules), querying D1 databases, managing KV stores, and integrating Cloudflare's edge computing infrastructure into agent-driven DevOps and serverless deployment workflows.

Elastic REST API for Elasticsearch, Kibana, and the ELK Stack observability and search platform. Enables AI agents to perform full-text and vector search across indexed documents, handle log analytics and query (EQL/KQL/Lucene) workflows, access Elastic Security SIEM detection rules and alerts, retrieve observability APM traces and metrics, manage index and data stream lifecycle, handle machine learning anomaly detection and classification, access Elastic AI Assistant integration, retrieve Kibana dashboard and visualization data, manage Elasticsearch cluster health and node management, and integrate search and analytics with data pipelines and applications.

Official MCP server from the Jotai team (jotaijs org) for Jotai — the primitive and flexible state management library for React. Enables AI agents to access Jotai documentation, API references, and usage patterns for building React applications with Jotai's atomic state model.

Official Quarkus extension enabling Java developers to build MCP servers using the Quarkus framework — exposing tools, resources, and prompts via Quarkus CDI beans, integrating with Quarkus developer experience (hot reload, native compilation, GraalVM), and enabling enterprise Java teams to build production-grade MCP servers with Quarkus's cloud-native capabilities.

Anthropic's official reference MCP server for browser automation via Puppeteer/Chromium. Gives agents the ability to control a real browser — navigate pages, click elements, fill forms, take screenshots, and execute JavaScript.

Official CircleCI MCP server enabling AI agents to interact with CircleCI's CI/CD platform — querying pipeline runs, monitoring build status, analyzing test failures, managing contexts and environment variables, and integrating CI/CD data into agent-driven DevOps workflows.

Official PostHog MCP server enabling AI agents to interact with PostHog's product analytics platform — querying events, trends, funnels, cohorts, feature flags, and experiments from an open-source analytics stack.

Official Quarkus MCP Servers — a collection of MCP server implementations built with Quarkus Java framework — providing production-quality filesystem, git, and fetch MCP servers with Quarkus's native compilation and low-memory footprint, offering Java-ecosystem alternatives to Node.js reference implementations.

Supabase is an open-source Firebase alternative that bundles four distinct APIs over a single Postgres database: the PostgREST auto-generated REST API (instant REST endpoints from your table schema), the Auth API (JWT-based user authentication with OAuth providers, magic links, and OTP), the Storage API (S3-compatible object storage with access policies tied to Row Level Security), and the Realtime API (Postgres CDC websocket subscriptions). Edge Functions (Deno Deploy) provide serverless compute. All APIs are governed by Row Level Security (RLS) policies defined in Postgres — the data access rules live in the database, not in application code.

Official Unleash MCP server enabling AI agents to interact with Unleash's feature management platform — querying feature flag states, creating and updating toggles, managing strategies and rollout rules, and integrating Unleash's feature flag system into agent-driven release management and experimentation workflows.

Official MotherDuck MCP server enabling AI agents to run SQL analytics with DuckDB — querying local files (Parquet, CSV, JSON), cloud-hosted MotherDuck databases, and performing in-process analytics without spinning up a cluster.

Supabase's official MCP server provides AI agents with direct access to manage Supabase projects including PostgreSQL databases, authentication, storage, and edge functions.

A single-binary CLI and MCP server that provides unified natural language and structured access to 15+ biomedical databases (PubMed, ClinicalTrials.gov, ChEMBL, UniProt, etc.) across 12 entity types including genes, variants, drugs, and clinical trials.

Docs MCP server enabling AI agents to scrape, index, and search documentation from any website — ingesting documentation pages, indexing their content with vector embeddings, and providing semantic search over the indexed docs to give agents accurate, up-to-date answers from any online documentation source.

Enhanced filesystem MCP server by cyanheads providing comprehensive file system operations for AI agents. Extends the basic MCP filesystem server with additional capabilities including recursive operations, pattern matching, file metadata, and improved error handling — a quality alternative/complement to the official filesystem MCP.

MCP Discovery CLI tool built in Rust enabling developers to discover and inspect MCP server capabilities — connecting to any MCP server and listing its tools, resources, and prompts, validating server implementations, and providing a lightweight CLI for MCP server exploration and debugging.
