Claude Desktop Companion

Archivist Nexus

Your campaign memory, wired into Claude in minutes

Archivist Nexus is a desktop installer that configures Claude Desktop with the Archivist MCP — plus optional companions for NotebookLM, Foundry, Notion, and Obsidian — so you can ask Claude about your table without editing config files.

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.

Five MCPs. One wizard.

Archivist AI

Required

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

NotebookLM

Optional

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

Foundry VTT

Optional

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

Notion

Optional

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

Obsidian

Optional

Search and update vault notes grounded in your Archivist history.

Ask Claude with full campaign context

Once Nexus finishes setup, Claude can pull from years of session history, character arcs, and open plot threads — then optionally act on Foundry, Notion, Obsidian, or NotebookLM through the companions you chose.

“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.
