How to use "AssignCodingAgent" prompt (GitHub MCP Server) in another MCP client?

[doggy8088]

When I install the GitHub MCP Server into tools other than GitHub Copilot or the GitHub Copilot Coding Agent, it doesn't seem to work correctly. Are there any documents, videos, or use cases that could help me understand this prompt resource?

From what I’ve seen, the AssignCodingAgent prompt is designed specifically for GitHub’s own Copilot MCP client and relies on internal context exchange that other MCP clients don’t implement yet.

At the moment, there’s no public documentation or SDK example showing how to use that prompt outside of the Copilot environment. If you try it in a different MCP client, it won’t resolve correctly because the prompt expects GitHub-specific session tokens and capabilities (like repo context and file diffs).

The best workaround right now is to use a custom MCP client that proxies those capabilities through the GitHub MCP server API — but that’s still experimental. I’d keep an eye on the MCP specification repo
for upcoming examples or compatibility layers.
