ModWrench

One wrench. Every mod platform. No data kept.

ModWrench is a Model Context Protocol (MCP) server that lets your AI assistant talk to mod platforms on your behalf. Discover mods, read changelogs, check versions, browse by tag, manage your modding workflow — from inside Claude Desktop, Claude Code, Cursor, ChatGPT, or any MCP-compatible client.

ModWrench is a bridge. It holds nothing about you. Your API keys live in your OS keychain. Your conversations stay in your AI client. Nothing is logged, nothing is sent anywhere except the platforms you're already using.

Built by a tinkerer who didn't see this coming. The modding community deserves better tooling than what the platforms ship by default — so here's a wrench.

What it does today

ModWrench bridges four of the biggest modding platforms on Earth, plus a local workbench for diagnostics:

• Nexus Mods — 50M+ users, the dominant home for Bethesda games (Skyrim, Fallout, Starfield), plus thousands of other titles
• mod.io — the cross-platform UGC backbone for PC, console, and mobile, embedded in hundreds of games
• Thunderstore — 270+ communities, the home of Unity co-op modding (Lethal Company, Valheim, R.E.P.O., Risk of Rain 2, Dyson Sphere Program, BONEWORKS, and more)
• Modrinth — the open-source Minecraft hub (mods, modpacks, plugins, datapacks, resourcepacks, shaders). 75% of ad revenue to creators, REST API with no auth needed
• Workbench — local-filesystem awareness: which games are installed, which mod manager you use, what your load order looks like, and what your crashlog actually says

Each capability is a separate MCP package (@modwrench/nexus, @modwrench/modio, @modwrench/thunderstore, @modwrench/modrinth, @modwrench/workbench). Install one, some, or all — same wrench, your choice of attachments. The CLI meta-server (@modwrench/cli) composes whichever you've configured into a single MCP entry.
