+### Added

+- `mcp doctor`: new subcommand diagnoses a broken or missing MCP setup by inspecting plugin files, credentials, editor registrations, Claude Code's plugin registry, and Codex's `config.toml`, optionally performing a live initialize handshake against each server. `install` now points users at it when credentials are configured or warnings occur. (#324)
+- `mcp update`: new subcommand reads the install manifest to update the plugin and re-register it across all previously configured editors, without requiring the user to re-specify editor names. (#324)
