This is good. Wonder how we can tie it from the FunctionBuilder functions...

[He-Pin]

I think now, you can attach the xtr as prefix, wdyt @jam01 ,thanks for the input,nice idea.

[jam01]

Looks good to me!

[He-Pin]

@jam01 Seems like you are building xtr on sjsonnet 0.6.0? I think we should add more document to this project.

[jam01]

Yes, I'm adding a couple of things on top of 0.6.0.

What do you mean by document? To my fork?

[He-Pin]

@jam01 I mean the extension point of sjsonnet, our data mapping pipeline is built on sjsonnet too.

[jam01]

Which data mapping is that?

[He-Pin]

We are using jsonnet to transform our mcp server data model with different data source, and export that as a tool

[jam01]

The other changes I've made would require a larger surface and I haven't quite figured out how to hide some things behind feature flags, but I'm open to talk about them.

Would be interested to read more about your project as well.
