OpenMemory MCP connection terminates immediately after initialization with Claude

[capoyeti]

Hi all,

I'm running Claude desktop on a Mac (15.5) and have been using DesktopCommander as the only existing MCP in Claude, I've tried to install OpenMemory but am getting a disconnect straight after Claude starts up.

Environment: OpenMemory containers are running correctly (MCP, vector store, and UI)
Symptoms:

MCP successfully initializes with Claude: [supergateway] SSE connected
Connection immediately closes after receiving protocol info
Logs show: Server transport closed unexpectedly, this is likely due to the process exiting early
Curl test to SSE endpoint works, proving the server is responding correctly

Technical details:
Claude client (v0.1.0) connects successfully
Server response includes protocol version 2025-03-26
The issue appears to be in maintaining the SSE connection, not in establishing it
ECONNRESET error suggests the connection is being reset after initial setup

Verification steps performed:
Restarted all containers in proper order (vector store → UI → MCP server)
Verified server responds correctly to direct HTTP requests
Confirmed all three containers are running and healthy
Examined server logs showing successful connection initialization but premature termination

I‘m facing the same issue. I can connect OpenMemory MCP with Cursor, but cannot connect with Claude desktop.
