[Feature Request]: Access to remote MCP Servers/Tools via OAuth on behalf of Users

[nheidloff]

Hi, I'd like to be able to connect to remote servers like https://api.githubcopilot.com/mcp/ directly without having to run anything locally.

For agents to work on behalf of users, OAuth needs to be supported so that MCP tools can be run on behalf of users. For example accessing https://github.com/github/github-mcp-server with separate personal credentials without one PAT (personal access token) only.

Thanks!
