Use to run a headless-browser CDP endpoint, replace a Chromium process, attach over CDP, enable real layout and screenshot surfaces, or diagnose CDP discovery, connection, and target startup—even when Moli is not named."
}

Run Moli's CDP Server

Run one Moli CDP server and connect the requested CDP client to its endpoint. Preserve the client's existing API where Moli supports it.

Workflow

Resolve moli from PATH. If it is unavailable, install the latest prebuilt release for the current platform:

Linux or macOS:
```
curl --proto '=https' --tlsv1.2 -fsSL \
  https://github.com/lexmount/moli/releases/latest/download/moli-installer.sh | sh
```
On Windows, use PowerShell:
```
powershell -ExecutionPolicy ByPass -c "irm https://github.com/lexmount/moli/releases/latest/download/moli-installer.ps1 | iex"
```
Resolve the installed binary again and run moli --version. The default location is ~/.local/bin/moli on Linux/macOS and %LOCALAPPDATA%\Moli\bin\moli.exe on Windows when it is not yet on PATH.
Start moli serve on the default loopback endpoint http://127.0.0.1:9222.
Add --layout when the workflow needs real element geometry, coordinate input, screenshots, PDFs, or screencasts. Add --resource only when all optional visual/media resources are required.
Probe /json/version before connecting the client.
Connect with the client's remote/attach API; do not launch a second bundled browser.
Close CDP clients cleanly, then stop the Moli server if this workflow owns it.

Playwright over CDP

import { chromium } from "playwright";

const browser = await chromium.connectOverCDP("http://127.0.0.1:9222");
const context = browser.contexts()[0];
const page = context.pages()[0] ?? await context.newPage();

await page.goto("https://example.com");
console.log(await page.locator("body").innerText());

await browser.close();

Integration rules

Bind to 127.0.0.1 by default. Expose another host only when the user explicitly needs remote access and has addressed network access controls.
Treat Moli as a remote endpoint. Avoid Chrome launch flags and assumptions that require a local Chromium executable.
Expect selected CDP coverage, not complete Chrome protocol parity. Preserve explicit unsupported errors.
Use a unique port for parallel isolated runs.
Persist state intentionally with --profile-dir; otherwise keep runs disposable.
Pass proxy, cookie, resource, user-agent, and private-network policy to the Moli server, not to a nonexistent child browser process.

Read references/protocols.md for CDP discovery URLs, server options, client selection, and connection troubleshooting.
