    DISCORD.js-selfbot

    DISCORD.js-selfbot

    An unofficial discord.js fork for creating selfbots

    DISCORD.js-selfbot is an archived Node.js library based on discord.js that targets Discord user-account API behavior instead of normal bot accounts. It exposes structures for messages, guilds, interactions, status, activity, voice, video, and other user-specific Discord features. The project was built around Discord API v9 and backported selected functionality from later discord.js versions. It includes documentation, examples, tests, and npm distribution history, but the repository is no longer actively maintained. Because automating Discord user accounts violates Discord’s Terms of Service and can lead to account penalties, this project should be treated as a risky proof-of-concept or research library. It is not appropriate for compliant production bot development.

    MCP Toolbox for Databases

    MCP Toolbox for Databases

    Open source MCP server that exposes database tools for AI agents

    GenAI Toolbox, also known as MCP Toolbox for Databases, is an open source server designed to simplify how generative AI applications interact with databases. It provides a central service that exposes database operations as reusable tools that can be consumed by AI agents and developer workflows. It handles common infrastructure concerns such as authentication, connection pooling, and performance optimization so developers do not have to implement them individually in each application. By defining tools and data sources through configuration files, developers can standardize how AI systems access and operate on database resources. GenAI Toolbox is designed to integrate with agent frameworks and development environments so that AI assistants can execute database-related tasks with proper context and security. It also supports observability through built-in metrics and tracing capabilities, allowing developers to monitor how tools are used and debug interactions.

    Mocha

    Mocha

    A feature-rich JavaScript test framework running on Node.js

    Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases. Hosted on GitHub. Mocha runs in the browser. Every release of Mocha will have new builds of ./mocha.js and ./mocha.css for use in the browser. Mocha is the most-depended-upon module on npm and Mocha is an independent open-source project, maintained exclusively by volunteers. Given Mocha’s use of function expressions to define suites and test cases, it’s straightforward to generate your tests dynamically. No special syntax is required — plain ol’ JavaScript can be used to achieve functionality similar to “parameterized” tests, which you may have seen in other frameworks.

    WebTorrent

    WebTorrent

    Streaming torrent client for the web

    WebTorrent is a streaming torrent client for node.js and the browser. YEP, THAT'S RIGHT. THE BROWSER. It's written completely in JavaScript – the language of the web – so the same code works in both runtimes. In node.js, this module is a simple torrent client, using TCP and UDP to talk to other torrent clients. In the browser, WebTorrent uses WebRTC (data channels) for peer-to-peer transport. It can be used without browser plugins, extensions, or installations. It's Just JavaScript™. Note: WebTorrent does not support UDP/TCP peers in browser. To make BitTorrent work over WebRTC (which is the only P2P transport that works on the web) we made some protocol changes. Therefore, a browser-based WebTorrent client or "web peer" can only connect to other clients that support WebTorrent/WebRTC.
