+### Added
+
+- **VSCode Copilot MCP Mirroring**
+  - When Copilot is a configured agent, MCP server configuration is now mirrored to `.vscode/mcp.json` using the VSCode-specific schema (`"servers"` + `"inputs": []`)
+  - Ensures GitHub Copilot agents in VSCode can discover MCP servers registered via `coldbox ai mcp` commands
+  - `.vscode/mcp.json` is written alongside the root `.mcp.json` whenever `generateMCPJson()` runs (install, refresh, MCP add/remove)
