+### Workspace MCP servers
+
+- Workspace MCP configuration lives in `.vscode/mcp.json`.
+- Prefer the `github` MCP server for live GitHub context such as issues, pull requests, status checks, branches, commits, releases, and cross-repo search. It is intentionally configured as read-only, so do not plan on it for creating or editing GitHub resources.
+- Prefer the `playwright` MCP server for browser-driven UI validation, repro steps, navigation, form interactions, screenshots, console inspection, and network checks when validating frontend behavior.
+- If `.vscode/mcp.json` changes, reload the VS Code window before assuming the new MCP configuration is active.
