Grimoire for Gamemasters

zafety-vibin/grimoire-mcp

Connects Claude or ChatGPT to your live TTRPG campaign data at ttrpg.bot via OAuth. Exposes 41 tools across NPCs, locations, factions, quests, session recaps, and knowledge graphs. You can parse unstructured notes into entities, query relationships between characters, generate rumors grounded in your actual world state, or pull the narrative context from your last three sessions. Includes a visibility model so player accounts see only player-knowledge entities while GMs get the full picture. Useful if you're running a campaign with enough moving parts that you need structured lookups during prep or play, or if you want the AI to answer questions about your world without hallucinating facts you never wrote.
