[Question]: MCP server implementation

• K8sGPT Operator

Steps to reproduce

Connect to k8sgpt through MCP server

Expected behaviour

k8sgpt provides an MCP server that platforms like Claude can connect to and uses without leaving the interface

Actual behaviour

No support for MCP server

Additional Information

Would like to know if MCP server support is on the map for k8sgpt or is it out of scope for this project? I do see overlap in this but maybe slight separation where the reasoning part is offloaded to external party and the project just focus on exposing tools to them.

Taking a look at this, have some ideas to try out.

[ronaldpetty]

Made a prototype. Here was the basic idea.

• clone k8sgpt
• added hardcorded MCP server
• launch at startup
• register "hello" tool that appends results

Nothing perfect, but proves it can be done. Next I suppose is to think about what a good enough solution might look like.

go build -o mybuild
mybuild serve

% curl -N --http2 -H "Accept: text/event-stream" http://localhost:9999/sse
event: endpoint
data: http://0.0.0.0:9999/message?sessionId=3c8ebbcc-35f1-468a-8228-9e7c8e33dbab

% curl -X POST -H "Content-Type: application/json" \                               
     -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"hello_world","arguments":{"name":"Alice"}}}' \
     "http://localhost:9999/message?sessionId=86d58e1d-a584-4c0e-982f-eed8756da228"
{"jsonrpc":"2.0","id":1,"result":{"content":[{"type":"text","text":"Hello, Alice {\n  \"errors\": null,\n  \"problems\": 0,\n  \"provider\": \"\",\n  \"results\": null,\n  \"status\": \"OK\"\n}!"}]}}

I need to chat with the team because we have a few places something like this could live.

Awesome work @ronaldpetty do you think we would implement this in practice, as an external module/analyzer etc?

[ronaldpetty]

@AlexsJones the primary design is that MCP is pull based (MCP client asks MCP server for tool execution results, the server being K8sGPT).

If we used the Operator, we could just read Results.

If we used the CLI, we could potential do it via k8sgpt serve or through exposing an endpoint and/or port (similar to above).

I don't exactly remember k8sgpt serve purpose (aside development) so maybe that is not the way.
