[GitHub integration] Private personal repo visible in picker but inaccessible via connector

Screenshot

What's Wrong?

Claude.ai can discover my private GitHub repository in "Add from GitHub", but the GitHub connector cannot read it.

GitHub account:
TtomSt

Private repository:
TtomSt/dentflow

Public repository:
TtomSt/ai-advisory-board

Observed behavior:

• Authentication succeeds as TtomSt
• Public repo TtomSt/ai-advisory-board is readable
• Private repo TtomSt/dentflow returns 404
• Repository search through the connector only returns the public repository
• "Add from GitHub" can see and select TtomSt/dentflow
• Selecting the repo inserts the repository URL into the chat
• When Claude uses the GitHub connector, the private repo is still not visible

GitHub-side configuration:

• The normal "Claude" GitHub App is installed
• Repository access is set to "All repositories"
• TtomSt/dentflow is covered by that installation

Separate connector behavior:

• "Claude Github MCP Connector" appears under Authorized GitHub Apps
• It does NOT appear under Installed GitHub Apps
• GitHub previously displayed:

"Claude Github MCP Connector has not been installed on any accounts you have access to."

This creates the following behavior:

Public repositories:
WORK

Private repositories:
FAIL with 404 / invisible to connector

I have already tried:

• disconnecting and reconnecting the GitHub connector
• starting a fresh Claude chat
• using + → Add from GitHub
• selecting TtomSt/dentflow directly
• authorizing Claude Github MCP Connector again
• verifying the normal Claude GitHub App has All repositories access

The issue persists.

This appears similar to:
#91416
#79083

What Should Happen?

After selecting TtomSt/dentflow through "Add from GitHub", Claude should be able to read the repository tree and file contents through the authenticated GitHub integration.

Steps to Reproduce

1. Use a personal GitHub account with a private repository
2. Install the Claude GitHub App with All repositories access
3. In Claude.ai, open a new chat
4. Click + → Add from GitHub
5. Select TtomSt/dentflow and main
6. Add the repository
7. Ask Claude to list the root-level files
8. Claude invokes the GitHub connector
9. Connector authenticates successfully as TtomSt
10. Private repository returns 404 / is not visible
