Apify MCP Server is an MCP server from Apify that lets AI assistants use Apify Actors as tools for web search, data extraction, scraping, browsing, and automation. Its hosted endpoint at mcp.apify.com supports Streamable HTTP and OAuth, while a local stdio distribution is available through the @apify/actors-mcp-server package. The server dynamically discovers Actors from the Apify Store, loads their input schemas, runs them, and exposes results through Apify datasets and key-value stores. It also provides tools for searching Apify documentation, inspecting and managing Actor runs, tasks, schedules, builds, and source files. Tool selection can be restricted through URL parameters or CLI flags, and the server supports agentic payment mechanisms including AGI, direct x402, and Skyfire.

AstrBot is an open-source all-in-one AI agent chatbot platform and development framework that connects instant-messaging platforms with LLM services, plugins, multimodal features, MCP, skills, knowledge bases, persona settings, and automatic context compression. It supports platforms including QQ, Telegram, WeCom, Feishu, DingTalk, Slack, Discord, LINE, and others, and can connect to services such as OpenAI-compatible APIs, Anthropic, Gemini, Ollama, LM Studio, Dify, Coze, and Alibaba Cloud Bailian. Its plugin system offers one-click installation of more than 1,000 plugins, while its agent sandbox isolates code and shell execution and supports session-level resource reuse. AstrBot provides a WebUI and web ChatUI with agent sandbox and web-search support, and can be deployed with uv, Docker or Docker Compose, desktop applications, or other documented deployment methods.

OpenMausBot is an open-source, local-first chat application for managing a team of AI bots as separate contacts. Each bot can have its own personality, model, conversation thread, computer, and connected applications, using agents launched through locally installed Claude, Codex, or Grok command-line tools and existing user logins. A local harness server on 127.0.0.1 manages agent processes, transcripts, keys, and events in the user's local OpenMausBot data directory. Bots can work through a cloud Linux desktop, an isolated local virtual machine, or—where supported—the host computer. Shell commands, file edits, and questions are routed through a permission broker and shown as approval or response cards. The application includes model selection, bot and conversation management, browser-accessible desktop takeover, and connected applications through Composio, including services such as Gmail, Slack, GitHub, Notion, and Linear. The repository provides desktop distributions for macOS, Windows, and Ubuntu, with Ubuntu Wayland host control disabled according to the README while a stated issue is resolved.

Universal Modder is an open-source toolkit by rehan-remade for AI coding agents that create offline, single-player mods for PC games. Its skills and tools identify a game's engine and existing modding route, inspect code and files, back up saves, build a working mod slice, generate art, 3D assets and audio through the fal MCP server, test the result in the running game, package it, and record findings for later agents. The repository supports Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and other agents that read AGENTS.md, and includes the Python `um` CLI for game scanning, asset generation and processing, Windows automation, save management, video capture, publishing checks and a shared knowledge base of game-specific field notes. Its rules restrict use to games owned by the user and offline or single-player work; they prohibit online cheats, anti-cheat or DRM bypasses, and distributing game files or decompiled code. The repository is MIT licensed and requires Python 3.10+ and ffmpeg; Blender is used for 3D-to-sprite rendering.

Project AIRI is a self-hosted AI companion for creating virtual characters or digital pets, with Live2D or VRM avatars and real-time voice chat. It connects to multiple model providers and can interact through Discord, Telegram, and games including Minecraft and Factorio. The project supports web, macOS, and Windows, and provides installation options through Winget, Scoop, and Homebrew Cask.
