Add GitHub Copilot CLI as a supported MCP client#5287
Merged
Conversation
Copilot CLI reads MCP server entries from ~/.copilot/mcp-config.json using the standard mcpServers map. Register it with type "http" for streamable HTTP and SSE for the legacy transport, matching the behaviour we already use for VS Code and Cursor.

Summary
GitHub Copilot CLI supports MCP servers via
~/.copilot/mcp-config.jsonusing the standardmcpServersmap format that ToolHive already handles. Adding it here means users can runthv client register copilot-cliand have ToolHive-managed servers wired up automatically, alongside the other 27 supported clients.The Copilot CLI docs list four transport
typevalues (local,stdio,http,sse). Since ToolHive always proxies servers as streamable HTTP, registered entries get"type": "http"(matching the VS Code / Cursor pattern), with"sse"reserved for the legacy SSE transport.Type of change
Test plan

Yes.
copilot-cliis now a valid argument tothv client register,thv client remove, and shows up inthv client status.
