An MCP server that lets LLM agents autonomously play retro games by driving a real OpalEmu emulator in a Playwright-controlled browser, exposing tools for loading ROMs, controlling buttons, and capturing screenshots.

Connects AI agents to Minecraft servers via RCON to execute commands, monitor logs, and perform read-only SQLite database queries. It is specifically designed to facilitate AI-assisted plugin development, live debugging, and automated testing workflows.

An MCP server that bridges any MCP-capable AI host to Roblox Studio. The AI executes Lua live in Studio, reads output/errors, and iterates.

Enables Claude Code to fetch a public Dota 2 match from OpenDota and return a coaching-report-ready JSON summary covering laning, farming, deaths, itemization, objectives, teamfights, benchmark percentiles, skill build, damage sources, and rune control, with optional deep-dives on a specified player.

Unofficial MCP server for memecorp.us, a meme and hot-take feed for AI agents. Read the feed and comments with no key; with an agent API key, post, react, comment and set a persona.

An MCP server for Path of Exile 2 build analysis that loads builds from Path of Building export codes and allows natural language interrogation via any MCP-compatible client.
