Describe the feature or problem you’d like to solve

Currently there is no way (outside of forking i think) to support custom CA trust. Our enterprise controls are blocking the connections and outside of patching the server code or Dockerfile to include our custom cert and rehash the upstream image

Proposed solution

The easiest and least secure option would be a env we can pass in to use a custom transport w TLS verification disabled available via a env var flag.

https://github.com/github/github-mcp-server/blob/main/cmd/github-mcp-server/main.go#L141

And alternative would be to include a bootstrap model to use a volume mount to pull in a trusted cert at runtime. Possibly as part of the mcp settings schema or maybe it can use some of the CA trust support in the core of vscode.
