Congratulations on the new release! Update run smooth.
I have a couple of questions regarding MCP. Is there any documentation available for MCP and for debugging it? I’m unable to connect via OpenWebUI or via curl.

@hexed crater can add more details w.r.t to NABox implementation

#

Did you enable MCP in preferences?

regal loom
#

Yes

hexed crater
#

interesting, what does curl say ?

#

You also have to generate a token by the way

curl -X POST https://grafana.xxxxxx/mcp -H "Authorization: Bearer 6dba8xxxxb612d9" <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" /> <link rel="icon" type="image/svg+xml" href="/assets/favicon-DhTzhEKd.ico" /> <meta name="viewport" content="minimum-scale=1, initial-scale=1, width=device-width, user-scalable=no" /> <title>NAbox</title> <script type="module" crossorigin src="/assets/index-CXlQ2WE1.js"></script> <link rel="stylesheet" crossorigin href="/assets/index-D9QzQSYr.css"> </head> <body> <div id="root"></div> </body> </html>

looking good

#

-L would make curl follow redirect, or you can add the trailing / in your command

Let's apply the good old method

#

but after rebbot it's not up again, only after disable and enable it by hand

hexed crater
#

Ok I wonder what makes that different for you, I need to do some tests, thank you !
