Ash-AI MCP and Cursor

My MCP config in Cursor:

{
  "mcpServers": {
    "tidewave": {
      "command": "/Users/foo/mcp-proxy",
      "args": [
        "http://localhost:4000/tidewave/mcp"
      ]
    },
    "ash": {
      "command": "/Users/foo/mcp-proxy",
      "args": [
        "http://localhost:4000/mcp/ash_ai"
      ]
    }
  }
}

{
  "mcpServers": {
    "tidewave": {
      "command": "/Users/foo/mcp-proxy",
      "args": [
        "http://localhost:4000/tidewave/mcp"
      ]
    },
    "ash": {
      "command": "/Users/foo/mcp-proxy",
      "args": [
        "http://localhost:4000/mcp/ash_ai"
      ]
    }
  }
}

When I enable the MCP server in Cursor, the output from my Ash app run via

mix phx.server

mix phx.server

outputs the following endlessly:

```
[info] POST /mcp/ash_ai
[debug] Processing with AshAi.Mcp.Router
