I am trying to setup the supabase MCP in my n8n instance…
Was originally going to do this with an sql agent but thats gone now!
Here is the documentation…
But for the life of me I cannot get this thing to trigger.
Below is one of my setups of this but I have tried so many variants, including using the access in environments
Has anyone actually done this or have an idea on how to, having 10 tools this agent can use just isnt going to cut it.
I’ve got exactly the same problem. Works fine with other MCP servers but just not Supabase
Same boat, tried all types of different methods to get it running.
Can we get someone to tell us what we’re doing wrong?
Estou tentando o mesmo problema…
Ocorre o erro:
Failed to execute operation: Failed to connect to MCP server: MCP error -32000: Connection closed
By the looks of it it’s in the bug reports on their GitHub. So it’s recognised as an issue, just need to wait it out now
Looks like they got the issue resolved, at least I can use it in Windsurf AI now. But it doesn’t seem like I can use it with n8n. Has anybody had any luck?
Apparently it’s resolved in n8n. Someone else has managed to get it to work. I am going to do some testing tonight and see
Well, I still can’t get it to work on my end. I’m still getting the same error. I even tried getting a new API key to see if that was the issue, but no. I did the update, restarted Docker.
Any other suggestions? Can anybody verify that it is working?
Okay, we got it to work. The problem was we had the API key down in the environment field, which is wrong. It needs to be in the same field as the arguments right after access token.
I couldn’t manage to make it works. I updated to the last version of n8n and already provide the access-token value in arguments filed but it returns the same error. is there any modification rathere the suggested one?
Where do I find the MCP Client STDIO API tool in n8n, been looking for this? Please advise? Is this a community node or something?
@LordBumble I think you want this community node: n8n-nodes-mcp - npm
I am trying to setup the supabase MCP in my n8n instance…
@Dan_Smith I may be completely off track, but: why aren’t you using the built-in Supabase node as a tool for your MCP server?
Why do you prefer their “raw” MCP ?
Because my original post was pre dating n8n releasing their native MCP nodes… mine was simply the community node.
