do we need to pass token or auth ?

#

in the "Building from Source" section of the documentation does the harvest-mcp:local refer to a docker installation on the NABOX itself?

north sage Dec 16, 2025, 11:02 PM

#

Yes you have to pass a token generated in the security section in NAbox

#

That's a Bearer token

inner raptor Dec 17, 2025, 12:19 AM

#

is it better to use a docker container in openshift or local would be just fine

dreamy remnant Dec 17, 2025, 8:53 AM

#

@inner raptor Thank you ,Yup since it is avaible in NABOX , don't have manged external docker i was using same

#

@north sage Do you have exemple mcp json file ?

inner raptor Dec 17, 2025, 9:25 PM

#

No, I don't have an example mcp json file, I am just starting to wrap my head around it now.

#

meaning the implementation of the mcp server

tawdry wing Dec 18, 2025, 3:06 PM

#

@north sage

#

something like below may work

        "harvest-mcp-http-local": {
            "type": "http",
            "url": "http://1.1.1.1/mcp/",
            "headers": {
                "Authorization": "Bearer xyz"
            }
        },

north sage Dec 18, 2025, 3:10 PM

#

Yep, I have :

{
    "servers": {
        "nabox-lab-france": {
            "url": "http://nabox.fr.netapp.com/mcp/",
            "headers": {"Authorization": "Bearer <BEARER>"},
            "type": "http"
        }
    },
    "inputs": []
}

inner raptor Dec 18, 2025, 5:53 PM

#

and the MCP server is hitting the monitoring counters in Harvest, it doesn't touch any actual data on the clusters. Right?

north sage Dec 18, 2025, 6:13 PM

#

Correct, just presenting data that are in the database, it doesn't have any access to the clusters

inner raptor Dec 19, 2025, 12:51 AM

#

So, because my NABOX doesn't have access to github, I downloaded the zip file and extracted it. The extraction produced harvest-main/harvest-main/mcp folder structure. In the docs I saw that the path is harvest/mcp and I renamed harvest-main to harvest and copied the folder to /home/admin which resulted to a path to the MCP folder like so: /home/admin/harvest/mcp. When I cd to MCP folder and execute docker build command "docker build -f mcp/Dockerfile -t harvest-mcp:local ." I get the following error: [+] Building 0.0s (0/0) docker:default
ERROR: resolve : lstat mcp: no such file or directory

#

Actually after I specified the full path, the build started, but apparently the process goes again to a https source to load docker metadata and my server can't fetch it.

#

You don't need to build mcp in NABox. It already should have mcp bundled. @north sage

inner raptor Dec 19, 2025, 4:26 PM

#

then you just need to edit the mcp.json for the integration? Where in the folder structure is the file?

tawdry wing Dec 19, 2025, 5:40 PM

#

inner raptor then you just need to edit the mcp.json for the integration? Where in the folder...

These instructions are to use mcp with copilot plugin for example in vscode.

#

So, I use the syntax in the harvest installation documentation and create the mcp.json file in VS , first start HARVEST_TSDB_URL=http://your-prometheus:9090 /path/to/harvest-mcp/bin/harvest-mcp start --http --port 8082 (I can't find /path/to/harvest-mcp/bin/harvest-mcp to specify it)

@north sage When I worked on the MCP integration, I thought that I messed up the NABOX and because I had a snapshot on the VM, I restored it to the previous day snapshot. And I see now that the Grafana lost the historical data. I see the graphs are populating now from scratch. Is there any way to bring the historical data back? I would appreciate your help in that. Thanks!

north sage Dec 19, 2025, 8:15 PM

#

Restoring from a snapshot broke historical data ? Yes that is weird. Is the time correct ?

inner raptor Dec 19, 2025, 8:30 PM

#

also I had a clone, which I started and it is the same. The grafana dashboards are starting to plot anew. Where should I look at the time

#

Actually, the historic data is there when selecting earlier than 24 h.

#

Thank you, I have hard time configuring the MCP server and because I deleted the harvest folder I copied manually, I thought that I broke the NABOX. This is how it came to restoring from the snapshot.

north sage Dec 20, 2025, 12:02 AM

#

If data are actually there, it’s often because of labels change. It could be due to harvest ports that changed but it might be something else. @tawdry wing, you have a magic query to identify those ?

dreamy remnant Dec 24, 2025, 1:45 PM

#

@north sage i used same code still gettting error TypeError: fetch failed

{
"servers": {
"nabox-lab-france": {
"url": "http://nabox/mcp/",
"headers": {"Authorization": "Bearer <BEARER>"},
"type": "http"

},

}

north sage Dec 24, 2025, 2:36 PM

#

What would curl say if you test with -v and POST to the url (with trailing slash) with the token in -H ?

#

Let me know if you need the full command.

dreamy remnant Dec 24, 2025, 3:45 PM

#

curl -X POST -v --head -H "Authorization: Bearer <token >" http://nabox/mcp/

#

it is fixed now, token copy with extra character thank you 🙂

Could you please let me know how to build a mcp client i have a llm downloaded
