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.

AI Client

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

Optional companions

NotebookLM

Turn session notes into podcast-style recaps, player briefings, and infographics.

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.

What You Can Ask Claude After Installing Archivist Nexus

Once Nexus finishes, Claude has full access to your campaign history — sessions, character arcs, open plot threads — and can optionally act through the companion MCPs you chose: Foundry, Notion, Obsidian, or NotebookLM.

“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 NotebookLM.”

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.”

Malachi

“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.”
