How to specify arguments under tools

[likku123]

Hello,

This might be Naive question here. I have deployed MKP mcp server using tool hive and exposing the proxy service with an endpoint.

Now I am using this endpoint in my vscode under mcp.json and specified the url.

Till here it's working fine.

My question is how can I specify/implement the arguments specified here under tools ex: https://github.com/StacklokLabs/mkp#list_resources .

Any example toolhive mcp server manifest/yaml provided would be great.

Thank you !

Hi @likku123, I'm not sure I understand how you use this MCP server, but generally you ask the LLM something like "Please list the Pods in namespace foo" and the LLM should, if powerful enough, notice that the list_resources tool is available and issue a tool call.

I'm not sure this answer your question, could you please clarify your setup and what you want to achieve? Please provide YAML files of the resources you're using as well.

@blkt Basically, I tried listing the nodes(worker and CP nodes) in a cluster there are around 40 nodes in the cluster. When I list it metadata is getting truncated and I am getting partial information only. Might be the context is filling with metadata. I think in order to over come this there is a patch released with below arguments "exclude_annotation_keys.

{
  "name": "list_resources",
  "arguments": {
    "resource_type": "clustered",
    "group": "",
    "version": "v1",
    "resource": "nodes",
    "exclude_annotation_keys": [
      "nvidia.com/*",
      "kubectl.kubernetes.io/last-applied-configuration"
    ]
  }
}

To disable annotations, you can do:

{
  "resource_type": "namespaced",
  "namespace": "kube-system",
  "version": "v1",
  "resource": "pods",
  "include_annotations": false
}

Using the annotation exclusion feature, it would look as follows:

{
  "resource_type": "clustered",
  "version": "v1",
  "resource": "nodes",
  "exclude_annotation_keys": [
    "nvidia.com/*",
    "kubectl.kubernetes.io/last-applied-configuration"
  ]
}

@JAORMX
Where I have to specify this ? In the MCPServer manifest file or in any file?

[JAORMX]

Those are the MCP calls one would do to the mkp server. I tried those in our infra. They are already enabled in the server.

[likku123]

Meaning . Do I need to specify these arguments in my mcp.json file as arguments ?

Anything I have to modify in below config.

{
	"servers": 
	{
		"k8s": {
			"url": "https://mcp-testing.hacochu.com/mcp"
            }
	"inputs": []
}

[JAORMX]

No, those arguments are for MCP calls (done by the LLM) and not part of a configuration.

Got it. Thanks for providing the clarity.

Appreciate your help for the explanation.

Hopefully the present MKP version fix the issue.
