MCP Community node not working on Railway in "active" mode

[Kris_Ograbek]

Hi!

I get a weird behavior on Railway.com.

I’ve set up a Notion MCP. It works fine when I run it using “Test Workflow”.
But as soon as I switch to “Active” mode, I get Unrecognized node type: n8n-nodes-mcp.mcpClientTool

So it behaves as if I didn’t set the N8N_COMMUNITY_PACKAGES_ALLOW_TOOL_USAGE="true" variable… But I did.

What is the error message (if any)?

Please share your workflow

Information on your n8n setup

• n8n version: latest
• Database (default: SQLite):
• n8n EXECUTIONS_PROCESS setting (default: own, main):
• Running n8n via (Docker, npm, n8n cloud, desktop app): Railway.com
• Operating system:

Same issue here and in Railway, as well.

Hi,

Shouldn’t it be N8N_COMMUNITY_PACKAGES_ALLOW_TOOL_USAGE=true instead of N8N_COMMUNITY_PACKAGES_ALLOW_TOOL_USAGE=“true” (which would be a string instead of a boolean. Also i might think of something like worker / versus UI execution differences?

I’ve these configurations on Railway
N8N_ENABLE_COMMUNITY_NODES=true
N8N_COMMUNITY_PACKAGES_ALLOW_TOOL_USAGE=true

but same problem

I have the same issue, did you manage to solve it?

Same issue

[chchen]

I set N8N_COMMUNITY_PACKAGES_ALLOW_TOOL_USAGE=true in Docker env.
it’s work, n8n version: 1.84.0

did you figure it out?

edit: ok I see. You not only have to add to settings → shared variables but also have to click the share button on the same row and select which “boxes” to share with then finally, re-deploy.

still getting this error no matter what I try but this works perfectly on local install but not cloud installs like railway so i’ll stick to local
