+# Using Playwright MCP Server with Google Chrome Flatpak on Linux
+
+The Model Context Protocol (MCP) has revolutionized how AI assistants interact with external tools and services. 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. Install Google Chrome from Flathub
+2. Create a symbolic link that Playwright expects
+
+## Step 1: Install Google Chrome from Flathub
+
+First, install Google Chrome using Flatpak:
+
+```bash
+flatpak install flathub com.google.Chrome
+```
+
+## Step 2: Create the Symbolic Link
+
+Playwright expects Chrome to be located at `/opt/google/chrome/chrome`. 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. By creating a symbolic link, you get the best of both worlds: the security of Flatpak and the simplicity of standard Playwright configuration.
