The file is the only durable way to give a run its roots: there is no roots flag, and `--method roots/set` applies only to that one short-lived connection. Roots configured for a server (the same field the web UI's Server Settings writes) are advertised at connect, so a server that asks for `roots/list` — `@modelcontextprotocol/server-filesystem` does, to learn its allowed directories — gets them.
**Environment-variable semantics.** `MCP_CATALOG_PATH` is honored only when no ad-hoc target is given (positional command, `--server-url`, or `--transport`) — so a shell that exports it can still run one-off ad-hoc invocations without hitting the catalog/ad-hoc conflict. `MCP_STORAGE_DIR` sets the storage directory used by the OAuth persist backend (`<MCP_STORAGE_DIR>/oauth.json`); the per-file `MCP_INSPECTOR_OAUTH_STATE_PATH` override still takes precedence over it.

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).

## Auth token
The dev/prod backend guards every `/api/*` route with `x-mcp-remote-auth: Bearer <MCP_INSPECTOR_API_TOKEN>`. The browser recovers the token, in priority order (see `App.tsx` `getAuthToken()`): the `window.__INSPECTOR_API_TOKEN__` global injected into `index.html` on every page load (`server/inject-auth-token.ts`), then a `?MCP_INSPECTOR_API_TOKEN=…` query param, then `sessionStorage`. Injection is a no-op when auth is disabled (`DANGEROUSLY_OMIT_AUTH`). See the root [AGENTS.md](../../AGENTS.md) for the full rationale.
