Connect a tool once and it shares memory with every other tool you’ve connected. Claude learns something on Monday, Cursor knows it on Tuesday. Each connection takes one to three minutes.

​
What a connection gives your tool

Every connected tool talks to the same context lake: one per user or team, holding your context graphs (Personal, Teams, Agents). Agents read from one or many graphs and write to their own. The connection exposes four MCP tools. That’s the whole surface; your AI tool does no orchestration.

​
Two ways to authenticate

  • OAuth (Claude, Claude Code, ChatGPT): sign in through your browser once. No key to copy.
  • API key (Cursor, Windsurf, Antigravity, generic clients): a bearer token you generate in the app’s connect guide. Each tool gets its own key so you can revoke them independently. The full value is shown exactly once.
Server endpoints, if your client asks:

​
Pick your tool

Claude Code

Install the plugin, sign in via /mcp. ~1 min, OAuth.

Claude

Add a custom integration in Settings. ~3 min, OAuth.

Cursor

One-click install or paste the config. ~2 min, API key.

ChatGPT

Create an app in ChatGPT settings. ~2 min, OAuth.

Windsurf

Paste the config and restart. ~2 min, API key.

Antigravity

Direct SSE connection with header support. ~2 min, API key.

Any MCP client

Streamable HTTP or legacy SSE. ~2 min, API key.
The in-app guides at app.xysq.ai walk the same steps with your key and config pre-filled, and watch for your tool’s first call to confirm the connection is live. These pages mirror them for reference.
