+# @reaatech/agent-auth-proxy-server
+
+Identity-aware proxy server for agent-to-service communication. Ships as a Fastify plugin (exporting `buildApp` and `start` from `app.ts`) and a CLI binary (`agent-auth-proxy-server`).
+
+Handles API key authentication, OAuth2 authorization code flow with PKCE, JWT issuance, scope enforcement, proxied credential injection, and audit logging. Pairs with `@reaatech/agent-auth-proxy-core` for shared schemas and `@reaatech/agent-auth-proxy-client` for the typed HTTP SDK.
+
+## Install
+
+```bash
+pnpm add @reaatech/agent-auth-proxy-server
+```
+
+## Quick start
+
+```ts
+import { buildApp, start } from '@reaatech/agent-auth-proxy-server';
+
+// Build the app without starting it (useful for testing)
+const app = await buildApp();
+await app.ready();
+
+// Or start the full server with signal handling
+await start();
+```
+
+Or from the CLI:
+
+```bash
+npx agent-auth-proxy-server
+```
+
+Requires a PostgreSQL database and configuration via environment variables (see `.env.example`).
+
+## What's exported
+
+- **`buildApp()`** — Creates and configures a Fastify instance with all routes, plugins, and error handling registered. Returns the app without listening.
+- **`start()`** — Calls `buildApp()`, registers signal handlers, starts listening, and begins background cleanup timers. Returns the listening app.
