Static MCP Registry question

[erw444]

I was referred to this repository by GitHub Support, Ticket 3841364

My company is looking into setting up an MCP Registry for our GitHub Copilot Organization account.
We have set up a URL that serves a JSON file in the style of here:
https://docs.github.com/en/copilot/how-tos/administer-copilot/configure-mcp-server-access#simplestatic-registry

We have downloaded the Insider version of VSCode and noticed that the URL we set in our GitHub account is being appended to, which causes the Json file to not be found.

https:///mcp-registry/mcp-registry-0.0.3/githubSampleRegFile.json/v0/servers?limit=1
VS
https:///mcp-registry/mcp-registry-0.0.3/githubSampleRegFile.json

Is this how to configure this feature?
Is the Simple Static Registry configuration going to be supported?

Affected version

VSCode 1.106

Steps to reproduce the behavior

1. Configure static MCP registry file URL in our Enterprise GitHub account.
2. Setup copilot in VSCode 1.106
3. MCP registry is not able to be found, throws a Get Error in the logs.

Expected vs actual behavior

Expected: MCP registry file is found by VSCode when I log into my GitHub enterprise account.
Actual: Get error for the URL because the URL is being appended to.
