Thank you for your advice. I added that variable in coolify.:
But unfortunately it still doesn’t work:
Can you please explain what you mean with that?:
" In self-hosted setups, MCP support is tied to **agent mode **…" What is the agent mode?
" check that your container is started with: N8N_FEATURE_FLAG_MCP=true"
How can I check that the container ist started with that? Unfortunately I don’t know how to do that.
