One particularly powerful integration is the [Playwright MCP server](https://github.com/microsoft/playwright-mcp), which enables AI to control web browsers for automation tasks. This guide shows you the simplest way to get Playwright MCP working with Google Chrome on Linux using Flatpak. + +## The Simple Solution + +Instead of complex configurations, we'll use a two-step approach: +1.

We'll create a symbolic link pointing to the Flatpak Chrome binary: + +```bash +# Create the directory structure +sudo mkdir -p /opt/google/chrome + +# Create the symbolic link +sudo ln -s /var/lib/flatpak/exports/bin/com.google.Chrome /opt/google/chrome/chrome +``` + +## Step 3: Add to Claude Code + +If you're using Claude Code, you can quickly add the Playwright MCP server: + +```bash +claude mcp add playwright npx @playwright/mcp@latest +``` + +Or manually add this configuration to your MCP settings: + +```json +{ + "mcpServers": { + "playwright": { + "command": "npx", + "args": [ + "@playwright/mcp@latest" + ] + } + } +} +``` + +## That's It! + +Now Playwright MCP server will automatically find and use your Flatpak Chrome installation. + +## Test the Setup + +You can test that everything works by running a simple Playwright script: + +```ini +# Start Claude Code +claude + +# Ask something like +Use the playwright MCP tools to write a haiku in the https://note.thenets.org/playwright-example +# the Chrome Browser should open +``` + +## Why This Works + +- Playwright looks for Chrome at `/opt/google/chrome/chrome` by default +- Flatpak installs Chrome at `/var/lib/flatpak/exports/bin/com.google.Chrome` +- The symbolic link bridges this gap without complex configuration +- Chrome runs with all the security benefits of Flatpak sandboxing + +## Troubleshooting + +If the symbolic link doesn't work, verify the Flatpak Chrome path: + +```bash +ls -la /var/lib/flatpak/exports/bin/com.google.Chrome +``` + +If Chrome isn't at that location, find it with: + +```bash +flatpak list --app | grep Chrome +which com.google.Chrome +``` + +## Conclusion + +This simple two-step solution eliminates the complexity typically associated with using Flatpak browsers with Playwright.
