- Forward all following arguments unchanged (including tokens that look like mode flags).
- Dynamically import that app’s runner from `clients/{web,cli,tui}/build/index.js` (relative to the launcher build output) and call it **in-process** (no `spawn()`).
All configuration parsing, config-file loading, and server setup are handled by the app runners and by **core**; the launcher does not interpret config or env vars.
All configuration parsing, config-file loading, and server setup are handled by the app runners and by **core**; the launcher does not interpret server or client configuration, from files or from env vars. Its one exception is the debug switch described below.
**Error reporting.** A `--cli` failure is routed through the CLI's own error sink, so `mcp-inspector --cli` preserves the CLI exit-code map (`1` usage, `2` no-app, `3` auth-required, `4` unreachable, `5` tool-error) and its machine-readable `{"error":{…}}` stderr envelope — the same as invoking the CLI bin directly. `--web` / `--tui` failures print a human-readable `Error: <message>` and exit `1` (append `MCP_DEBUG=1` for the stack).
