On Next.js 14, also set `experimental.instrumentationHook: true` in `next.config.js`. ```ts theme={"theme":{"light":"github-light","dark":"github-dark"}} // src/instrumentation.ts export async function register() { if (process.env.NEXT_RUNTIME === 'nodejs') { const { manifest } = await import('manifest'); manifest(); } } ``` ### Laravel Call `manifest()` from a service provider, and add the entry to `config/services.php`: ```php theme={"theme":{"light":"github-light","dark":"github-dark"}} // app/Providers/AppServiceProvider.php public function register(): void { \Mnfst\manifest(config('services.manifest.key'), config('services.manifest.url')); } ``` ```php theme={"theme":{"light":"github-light","dark":"github-dark"}} // config/services.php 'manifest' => ['key' => env('MNFST_KEY'), 'url' => env('MNFST_URL')], ``` ## What Manifest covers Manifest heals a [recoverable request](/glossary#recoverable-request) with a JSON or form body up to 256 KiB. The SDK records every other request without healing it. In Python, the SDK sees `httpx`, `httpx2` and `requests`. In Node, the SDK sees the global `fetch` and the `http` and `https` modules, so it sees Axios too. In PHP, the SDK sees the Laravel `Http` facade, Guzzle, Symfony `HttpClient`, CakePHP and WordPress. It records a library with its own raw `curl_*` client but never heals it. The PHP SDK needs the `opentelemetry` extension, so it cannot run on shared hosting. Laravel Vapor and Bref need a Lambda layer that includes the extension. Without a writable temporary folder on the server, the SDK stops recording but keeps healing. In Hermes, the plugin sees tool calls to MCP servers reached over HTTP. A failed tool call shows the status `418` in the dashboard. This code stands for a failed tool call, never for a real API answer. The SDK retries a patched request once. A retry can repeat a side effect of the first request, so send an idempotency key when the API accepts one. A script that exits with `process.exit()`, `os._exit()` or a signal can lose its last requests, so let it end on its own. A PHP worker such as Laravel Octane or `queue:work` sends its requests only when it restarts. ## Check your install Each `doctor` command checks the install and the key. Run it in the folder and the environment of your app: ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}} mnfst run mnfst doctor ``` ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}} npx manifest doctor ``` ```bash theme={"theme":{"light":"github-light","dark":"github-dark"}} vendor/bin/manifest doctor ``` Outside Next.js, the Node command warns "Loads before your app" when your app calls `manifest()`. Check the setup screen instead. When the setup screen shows "Waiting for your first request", check that: * `MNFST_KEY` is set where the app runs * the app restarted after you set it * Manifest starts before the first API request * in PHP, the `opentelemetry` extension is active. When the setup screen shows "Connected. Waiting for a failing request", the install works. To open the dashboard now, send a JSON request that your API rejects with `400`, `404` or `422`.
