mw_activate_platformActivate an additional platform's tool set without restarting the meta-server. Use this when the user adds credentials or asks about a platform that wasn't loaded at boot. After activation, the new tools appear in the catalog and become callable. Returns the activation result (success with toolCount + baseUrl, or failure with reason — usually a missing-credential hint pointing at `modwrench auth l

Stateless \u2014 rendered fresh from the current catalog, holds nothing. Use when the user says "open the deck", "summon/show ModWrench", or wants a visual dashboard.

ModWrench
An MCP server that connects your AI assistant to mod platforms and to your own modding setup, so you can ask questions in your AI client instead of clicking through web UIs.
It runs on your machine. No account, no service, no server anyone operates.
Paste a crash log. Get the mod that caused it.
SomeArmorMod.esp is named as a suspect, and SomeArmorMod.dll is sitting at frame 2 of the call stack. ModWrench parsed the log and laid out what is in it. It did not decide the cause — that is the model's job, and the panel says so.
Search every platform you have connected, with the author on every row.
These panels are not screenshots of a website. Each one is an interactive MCP-UI resource that a tool returns inline with its answer — self-contained HTML with no external scripts, no stylesheets, no fetches and no images. Your MCP client renders it locally, or shows the text answer if it does not support MCP-UI yet. Nothing about it reaches a server.
One caveat worth knowing before you hit it. A client that does not support MCP-UI does not quietly ignore the panel — it puts the HTML into the conversation as text, and the model reads markup it can do nothing with. One panel is about 28kb, roughly 8,800 tokens, near 7% of a 128k context window. If that is happening to you, turn panels off:
MODWRENCH_UI=offSet it wherever your client puts environment variables. The payload drops from 28kb to about 130 bytes — a 219x reduction — and every tool keeps working exactly as before. Panels are on by default; this is opt-out, not opt-in.
What it does
Four attachments. Install one, some, or all — @modwrench/cli composes whichever you've configured into a single MCP entry.
Nexus Mods — search mods, read changelogs and file lists, check versions, browse trending and recently updated, preview what's inside an archive before downloading, reverse-lookup a file by MD5, and endorse a mod when you ask it to. (15 tools)
mod.io — search and browse mods across the games mod.io hosts; pull mod details, files, tags, stats, dependencies and comments. (17 tools)
Thunderstore — browse communities, search mods, read full version history, and resolve dependency trees. No credential needed; the read API is public. (9 tools)
Workbench — local, on your machine. Find your installed games, mod managers and loaders; read your load order out of MO2, r2modman or Vortex; parse a crash log from Crash Logger SSE, Buffout 4, NetScriptFramework or BepInEx; look a mod up across platforms; check known conflicts. (6 tools)
The conflict check reads two sources: LOOT's masterlist, fetched live for Bethesda games, and a small conflict list bundled inside the package for games LOOT does not cover. That bundled list ships empty — all three files contain [] — so today it asserts nothing. It is named here because it is a channel that could carry claims about someone's mod in a future release, and npx pulls the latest version automatically unless you pin.
Plus two meta tools for activating a platform mid-session and opening a visual panel.
49 tools. 48 of them read. One writes — see The one thing it writes.
