Query and Update Your Full TTRPG Campaign History with Archivist MCP

Archivist is a long-term memory layer for TTRPG campaigns. This MCP connector, hosted at mcp.myarchivist.ai/mcp, lets Claude, Cursor, Windsurf, ChatGPT, and other MCP-compatible clients read and write structured campaign data instead of relying on a single chat window.

“What happened in our last three sessions?”

“Summarize every open quest and who is involved.”

“Who are the most important NPCs in this campaign?”

“What do we know about the Thieves' Guild across all sessions?”

“Create a new NPC named Alice and link her to the Thieves' Guild.”

“Draft session prep based on unresolved plot threads.”
