One install. Every agent.

Paste a key into Cursor, Claude, Antigravity, or anything that speaks MCP. You do not replace the IDE.

{
  "mcpServers": {
    "hexum": {
      "serverUrl": "https://hexum.dev/mcp",
      "headers": { "Authorization": "Bearer hexum_live_…" }
    }
  }
}

Then the agent can work with a smaller bill and check your architecture.
