Connect an AI Assistant
Let ChatGPT, Claude, or another MCP-compatible assistant read and update your ClusterSim workspace. You approve access and can revoke it anytime from the Connected Assistants page.
Your ClusterSim server address
Paste this address into your assistant when it asks for an MCP server URL. It always matches the site you are on.
