Additional context

@Kludex can you review ?

[barnuri]

@dsp-ant can you look ?

[dsp-ant]

@Kludex any opinions? I personally understand why you would want this, but i think it would be better suited in your application as either a call before starting the server or as an extension to the FastMCP server class. I appreciate the effort but would politely decline adding this.

[Kludex]

I think it's more useful in the stdio case. Since nothing happens when you start the application.

But on the HTTP, it will be a bit noisy...

If it's in debug level then I think it's fine.

[barnuri]

ok i will change to debug

[barnuri]

@Kludex @dsp-ant moved it to helper method and class, I think its very useful, for example in my code when im using sse i will add a route that return this object in some route for example /info (like in rest api have swagger json doc)
the idea of it is to have something simple without creating a client that can be easily visible
same for using stdio and then i will use the debug log
i hope you would like it :)

@dsp-ant @Kludex can you tell me what do you think ?

[barnuri]

@ihrpr @jerome3o-anthropic can you review ?

[ihrpr]

Thank you for working on this!

Sorry for the delays in reviews. Suggested a few small changes as we should be good to go.

[Kludex]

How does the output look like? I think we should be careful here, it's easier to add more stuff, but not that easy to remove usually.

[dsp-ant]

I am closing this out since we haven't made much progress. I think this is mostly on us for screwing up reviewing this properly. Sorry @barnuri . I think in general we are still interested in the feeature, but mindful that we shouldn't add the underlying types to src/mcp/types.py since that file reflects the official protocol. This is an SDK feature only. If you are interested in redoing this ontop of the current state of the repo, please do so and ping me either via the MCP Contributor discord or on the PR and I will get to it.

Again, I am very sorry that we didn't review this in proper time and made the progress very slow.
