Cannot use GitHub MCP server

[K3UL]

Describe the bug

The documentation states that the tool ships with the GitHub MCP server. However, it does not seem to be the case. Tested on Windows and Debian.

Almost identical example from the docs :

Trying to list MCP servers, it comes up empty

Affected version

0.0.327

Steps to reproduce the behavior

Run copilot -p "Use the GitHub MCP server to list my open PRs" --allow-all-tools

Or use the command /mcp show in interactive mode.

Expected behavior

The tool should use the MCP, which allows it to do much more things than the gh cli, which it falls back to.

Additional context

No response

Thanks for the report! We're looking into this!

In interactive mode, I can run /mcp add and use the MCP without issue. However, after using only copilot -p one for that MCP, I cannot use it.
I will post a discussion to determine whether this is a known gap or user error.

This should be resolved as of v0.0.363. The GitHub MCP server is now a built-in server that auto-starts when you're authenticated and shows up in /mcp show. MCP servers also work in prompt mode (copilot -p) since that release. If you believe this isn't fully resolved, please feel free to reopen this issue.
