MCP SSE Service Connection Issue Solution
Problem Description
MCP SSE service only listens on 127.0.0.1:8000, cannot be accessed from external IP addresses
The --host 0.0.0.0 parameter is ineffective, service still binds to localhost
Causes "Connection refused" errors when plugins try to connect

step 1: Install Port Forwarding Tool sudo apt install socat -y

Step 2: Start MCP SSE Service

Step 3: Set Up Port Forwarding
socat TCP-LISTEN:8001,bind=0.0.0.0,fork TCP:127.0.0.1:8000
tep 4: Configure Client Connection
Update your MCP client connection configuration to:
{
"server_name": {
"url": "http://YOUR_IP/sse",
"headers": {},
"timeout": 50,
"sse_read_timeout": 50
}
}
