Claude Desktop Installer

Archivist Nexus, the Claude Desktop MCP installer

Archivist Nexus: Set Up Claude Desktop Without Editing Config Files

Archivist Nexus is a guided installer (macOS and Windows) that sets up Claude Desktop with the Archivist MCP, plus optional companions for Discord, Gemini Notebook, Foundry, Notion, and Obsidian. No JSON config editing required.

An active Archivist subscription is required

Nexus connects Claude to your Archivist account via OAuth. Without an active subscription and campaign data in Archivist, the integration cannot access your table's memory.

Archivist for Claude Desktop Plus Five Optional MCP Companions

One guided wizard handles the whole setup.

Core connection

Archivist AI

Required

Your campaign source of truth for sessions, characters, quests, journals, and timelines.

Claude Desktop

AI Client

The AI client Nexus installs into. Routes requests to Archivist and any companion MCPs you add.

Optional companions

Discord MCP

Let Claude Desktop search and post in Discord through a bot you create and explicitly connect.

Gemini Notebook

Turn session notes into podcast-style recaps, player briefings, and infographics. Listed as NotebookLM in the installer, its name before July 2026.

Foundry VTT

Draft quests and NPCs from Archivist context and push content into your live world.

Notion

Publish session summaries and wiki pages so player-facing docs stay aligned with the table.

Obsidian

Search and update vault notes grounded in your Archivist history.

Discord MCP Ships with Archivist Nexus

Connect Claude Desktop to Discord through an Archivist companion bot you create. The same bot can also record an additional simultaneous live session. Nexus installs the hosted Discord MCP, handles OAuth, and lets you choose the exact bot Claude can use.

The official Archivist bot is intentionally unavailable for Discord MCP, so you control the bot identity and its reach. Your bot can only see channels and take actions allowed by its Discord permissions. Discord MCP does not add those messages to Archivist campaign memory.

What You Can Ask Claude After Installing Archivist Nexus

Once Nexus finishes, Claude can use your approved Archivist campaign history and optionally act through the companion MCPs you chose: Discord, Foundry, Notion, Obsidian, or Gemini Notebook.

“What happened in our last three sessions?”
“Summarize every open quest and who is involved.”
“Draft session prep based on unresolved plot threads.”
“Turn last session into a player-facing recap for Gemini Notebook.”
“Post last session's recap in our Discord campaign channel.”
“Find the rules debate from Discord and start a thread with the answer.”

Want the longer versions? The Archivist Cookbook has full recipes for session prep, podcast recaps, and campaign infographics.

No manual JSON editing

Nexus backs up and merges your Claude Desktop config. You never touch claude_desktop_config.json by hand.

Bundled dependencies

Node, remote MCP tooling, and companion servers are installed and verified for you.

Verify before you finish

A built-in checklist confirms auth, binaries, and config before you restart Claude.

Real feedback from GMs using Nexus with Claude and Obsidian

“If you're using Claude with Archie and Obsidian then you're already 1000x ahead of normal AI users.”

“Ok I have to admit this just saved me so much work. I am using the Obsidian TTRPG vault by Josh Plunkett. Claude just stepped in, pulled the Archivist session info, and updated the Obsidian vault using the existing templates. All nice and seamless. I am having it look at my public-facing wiki vault now.”
