Packages

Provides an MCP server (stdio transport) that uses xlwings to automate Microsoft Excel through session-based operations (open workbook sessions, read/write cell data, apply formulas, manage worksheets/ranges/tables, and create charts), with configurable session TTL and limits.

Zen is a self-hosted, single-binary notes app that stores markdown notes in SQLite with tag-based organization, BM25 full-text search, and an optional MCP server for AI agent integration with note operations.

Developer-focused email sending API with powerful routing, parsing, and validation features for transactional email delivery.

BrowserStack's official MCP server that enables agents to programmatically manage and execute test cases, run manual/automated tests on real devices and browsers, debug test failures, and perform accessibility testing through natural language prompts integrated into IDEs like VSCode, Cursor, and Claude Desktop.

An MCP (Model Context Protocol) server that performs multi-step web research using Tavily Search and Tavily Crawl, then returns structured JSON (including documentation instructions) for an LLM to generate detailed markdown documents. Optionally supports secure file writing of research outputs when explicitly enabled.

GoPeak is an MCP server for Godot Engine that exposes a large toolset (scene/project editing, runtime inspection, screenshots/input injection, and LSP/DAP-style debugging) to AI clients via the Model Context Protocol. It supports tool exposure profiles (compact/full/legacy), dynamic tool groups, and cursor-based pagination for tool listings.

n8n is a fair-code workflow automation platform with native AI capabilities, enabling technical teams to build automations using a visual editor combined with custom JavaScript/Python code across 400+ integrations, including LangChain-based AI agent workflows.

ScreenHand is an open-source MCP server (stdio transport) that gives AI agents local control over macOS and Windows desktop UIs (via Accessibility APIs) and optionally browser automation (Chrome DevTools Protocol). It exposes a large set of tools for UI inspection, interaction (click/type/keys/scroll/menus/drag), perception/OCR fallbacks, job orchestration, and per-app “app mastery map” learning.

vMLX is a local inference server for Apple Silicon that runs MLX-based text/vision models and provides an OpenAI/Anthropic/Ollama-compatible HTTP API (plus image generation/editing and audio STT/TTS). It also advertises MCP support via a Python dependency.

wati-mcp-server is a Python Model Context Protocol (MCP) server that integrates with the WATI WhatsApp Business API, exposing MCP tools for messaging, contacts, template/broadcast messaging, media file handling, and conversation history retrieval (with pagination/filtering), plus a demo get_weather tool.

ZotLink is a Python MCP server that connects to a local Zotero instance and saves open scholarly preprints (e.g., arXiv and selected open preprint servers) into Zotero, including metadata extraction and attaching PDFs (or validated link fallbacks). It uses browser automation (Playwright) when needed and provides MCP tools for checking Zotero status, listing collections, extracting metadata, and saving papers.

A Python MCP server that searches for flight offers (one-way, round-trip, multi-city) and retrieves offer details using the Duffel flight search API. It exposes MCP tools like search_flights and get_offer_details and requires a Duffel API key provided via environment variable.

just-prompt is an MCP (Model Control Protocol) server that exposes a unified interface to multiple LLM providers (OpenAI, Anthropic, Google Gemini, Groq, DeepSeek, and Ollama). It provides MCP tools to send prompts to one or more models, run prompts loaded from files (optionally writing outputs to disk), list providers/models, and run a multi-model “board” workflow where a “CEO” model decides based on board member responses.

Local AI inference server supporting text generation (LLM), image generation, speech-to-text, and text-to-speech across CPU, GPU (Vulkan/ROCm), NPU (XDNA2), and Apple Silicon. Exposes an OpenAI-compatible REST API on localhost:8000 for drop-in integration with existing tools.

Converts any OpenAPI V3 REST API specification into a working MCP server automatically, enabling AI agents to call any REST API through MCP without writing custom integration code.

Provides an MCP server that lets an agent generate PlantUML diagrams (e.g., sequence/class/C4) and return embeddable URLs or images, plus encode/decode PlantUML for URL sharing.

MCP server implementation for QuickBooks Online integration

A universal preprocessing platform that converts documentation websites, GitHub repositories, and PDFs into structured AI knowledge assets, exportable to 16+ formats including Claude Skills, Gemini Skills, OpenAI GPTs, and vector database formats.

Provides an unofficial MCP server exposing vnstock (Vietnam stock/finance data) functionality as MCP tools, with multiple transport options (stdio, SSE, and HTTP streaming).

Valve's Steam Web API providing access to player profiles, game libraries, achievement data, game news, store information, and community features for the Steam gaming platform.
