What is WorldAnvil MCP?

WorldAnvil MCP is a bridge that connects AI assistants with the WorldAnvil platform. WorldAnvil is a world-building platform designed for writers, game masters, and creators to organize and create fantasy worlds, science fiction universes, or any fictional settings.

Usage examples

Create a character profile
As a game master, you need to create a series of NPC characters for an upcoming campaign. Through WorldAnvil MCP, you can quickly generate complete character profiles, including backstories, personality traits, and relationship networks.
Build a location relationship network
A writer is building a fantasy world and needs to ensure that the geographical and political relationships between various locations are logically consistent. Through MCP, you can quickly establish associations between locations.
Manage campaign secrets
A game master needs to record plot clues and secret information that only they know, and this content should not be visible to players.
