Improving access permissions for assets in a GitHub private repository

### Describe the feature or problem you’d like to solve

Hello,
When using AI agents like Claude Code and accessing a GitHub private repository via MCP, I’m unable to access screenshots embedded in issue or PR bodies.

Even if I can read the links listed in the body text, attempting to fetch asset links, returns a status code 404. It’s natural that 404 occurs since Claude Code doesn’t have access rights to my private repository, but if there were a way for MCP to directly access assets attached in the body, it would greatly help improve development workflows using AI agents.

### Proposed solution
Access permission for asset in a Github private repository via MCP
