MCP SSE failing to connect

[kneelesh48]

What happened?

Librechat fails to Connect to SSE

This is what my librechat configuration looks like

Do I need to expose port 3001 in the docker container?

Steps to Reproduce

1. Install librechat by using git clone
2. Enable mcpServers in librechat.yml
3. Run docker compose up -d

What browsers are you seeing the problem on?

TL;DR

You need to be running the SSE server beforehand, and it must be reachable to your instance.
