Nexus Desktop App Automates MCP Setup for TTRPG Campaign Management

Manually editing Claude Desktop config files to plug in MCPs for tabletop RPG campaigns gets old fast. One dev built a free desktop app called Nexus to handle the wiring — install and configure MCPs without touching JSON.

What Nexus Does

Nexus is a desktop installer and configurator for Claude Desktop MCPs targeting TTRPG campaign management. It supports five tools out of the box:

• Archivist — persistent campaign memory, keeps Claude up to date with your world lore
• NotebookLM — generate audio recaps from session logs
• Foundry VTT — pull character sheets, maps, and combat state
• Notion — read/write session notes in real time
• Obsidian — sync local markdown vaults with Claude

Practical Workflows

The author describes multi-tool queries that go beyond a simple installer. Examples include:

• Asking Claude about campaign history by pulling from Archivist
• Simultaneously fetching context from Foundry and campaign notes in Notion/Obsidian
• Generating NotebookLM audio recaps directly from session data
• Syncing campaign info (NPC stats, quest status) across all connected tools

Setup and Links

Nexus is available at the Archivist site. The Archivist MCP itself is open source on GitHub:

• Nexus app: myarchivist.ai/nexus
• Archivist MCP (GitHub): github.com/Astrotomic/mcp.myarchivist.ai

The author is curious what MCP setups other TTRPG groups use — productivity tools, coding tools, knowledge bases, or something else entirely.
