[Bug]: A timeout occurs when attempting to connect via MCP from LM Studio. #2120

Open

Description

@garmy-ja

crawl4ai version

0.8.6 - 0.9.2

Expected Behavior

Once you configure LMStudio's mcp.json as shown below, Crawl4AI is ready to be used as an MCP.

{
  "mcpServers": {
    "crawl4ai": {
      "url": "http://192.168.xx.xx:11235/mcp/sse",
      "headers": {
        "Authorization": "Bearer xxxxxxxx"
      }
    }
  }
}

Current Behavior

When attempting to establish an MCP connection from LMStudio to Crawl4AI, there is no response from Crawl4AI, and the connection times out after a delay of several tens of seconds.
Since version 0.9.0, Authorization: Bearer has been included in the headers, but the behavior remains unchanged.

Is this reproducible?
