Hi @jesselumarie!

This looks cool. Just converted it to draft until the SEP is accepted and a Typescript SDK release contains the changes needed.

It looks like some SDKs have already implemented this, and there's a related issue here: #861

(Edited)

[cliffhall]

The holdup on icons being an array instead of a space-separated list in a string has been merged in the SDK and is in the latest release.

@jesselumarie can you resolve the conflicts?

[jesselumarie]

@cliffhall just pushed up a resolved version 👍🏻

Hi @jesselumarie

Currently seeing the following in browser devtools:

That's owing to a change made to the Typescript SDK that aren't in your branch.

With the latest version TS SDK temporarily added on my local copy of your branch, I see the icon display when I connect to the simpleStreamableHttp.ts server

I have a pending PR to fix the SDK version: #883 so it will soon be possible for you to merge main and fix this on your branch.

@jesselumarie Still haven't got an everything server example of icons on tools, resources, and prompts, but need to do that for testing this. Otherwise, resolved conflicts, no errors, and server icon display / link works as expected.

@cliffhall i updated resources so they will show icons too, as well as removed the duplicate text issue. you can test it with this server claude spun up for me https://github.com/jesselumarie/mcp-icon-test-server. also updated the package.json to have the updated sdk.

@jesselumarie Tested with your example server that has icons for everything and it's looking good and ready to merge.

However, I'm not certain we need these changes to package-lock.json; there was no package.json change.

ah okay, let me revert that and npm install — i probably had stale local packages

[jesselumarie]

@cliffhall i think that's better — holler if you see any other issues

[cliffhall]

@jesselumarie looks like your change that removed the package-lock.json also reverted .github/workflows/claude.yml

[jesselumarie]

@cliffhall think it should be good now

LGTM! 👍
