**Note:** MCP servers are automatically configured by GitHub Copilot without requiring separate configuration files.
## Integration Points
| Component | Configuration | Purpose |
|-----------|--------------|---------|
| **VS Code** | Built-in Copilot context | Loads MCP servers automatically |
| **Codespaces** | Uses `devcontainer.json` | Pre-configures environment |
| **Copilot** | Reads `copilot-instructions.md` | Follows coding guidelines |
| **Documentation** | References guides | Provides developer guidance |
