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.
