Orbismo
Build a world your AI knows. Orbismo is a world-building knowledge platform for AI. Keep track of the people, places, events, and details that make up your world — then any AI you use can draw on it in any chat, so you never have to start over.
Connect the Orbismo MCP server and your AI reads and writes a connected knowledge graph you own: entities, relationships, timelines, lore, and your own world instructions. Organize separate worlds for your life, your work, and the stories you're writing — and share a world to build together with your team.
What you can do
- Capture your world — create and update entities (people, places, events, references, rules, and more) through natural conversation.
- Connect the dots — map relationships between entities and traverse an entity's neighborhood.
- Recall anything — search entities and lore, and read events back in chronological order on a timeline.
- Steer your AI — give a world its own standing instructions so any connected agent behaves the way you want.
- Keep worlds separate — switch between worlds, and share one to collaborate.
Getting started
-
Create a free Orbismo account at orbismo.com. New accounts get a coupon code for a free world to start building right away.
-
Add the server to your MCP client (Claude, ChatGPT, Cursor, Claude Code, or any MCP client):
{ "mcpServers": { "orbismo": { "url": "https://app.orbismo.com/api/v1/mcp" } } } -
Sign in when your client opens the browser — OAuth handles the rest. No secret to copy or store.
Full setup guides for each client are at help.orbismo.com/connect-ai.
Two ways to connect
- Connector URL (all worlds):
https://app.orbismo.com/api/v1/mcp— sign in with OAuth. Recommended. - Per-world API key: generate a key (
oc_live_…) under World Settings → API Connections and use the world-specific URLhttps://app.orbismo.com/api/v1/worlds/<world_id>/mcpwith anAuthorization: Bearerheader. You set read-only or read-write access when you create the key.
Transport & auth
- Transport: Streamable HTTP (the modern MCP transport)
- Auth: OAuth 2.1 + PKCE for the connector, or a per-world API key for world URLs
- Access: read-only and read-write both supported, scoped to your role
- Hosting: fully hosted at
app.orbismo.com— nothing to run locally
