Ryan Malloy 574fdc4959 feat: add snapshot size limits and optional snapshots to fix token overflow
Implements comprehensive solution for browser_click and other interactive tools
returning massive responses (37K+ tokens) due to full page snapshots.

Features implemented:
1. **Snapshot size limits** (--max-snapshot-tokens, default 10k)
   - Automatically truncates large snapshots with helpful messages
   - Preserves essential info (URL, title, errors) when truncating
   - Shows exact token counts and configuration suggestions

2. **Optional snapshots** (--no-snapshots)
   - Disables automatic snapshots after interactive operations
   - browser_snapshot tool always works for explicit snapshots
   - Maintains backward compatibility (snapshots enabled by default)

3. **Differential snapshots** (--differential-snapshots)
   - Shows only changes since last snapshot instead of full page
   - Tracks URL, title, DOM structure, and console activity
   - Significantly reduces token usage for incremental operations

4. **Enhanced tool descriptions**
   - All interactive tools now document snapshot behavior
   - Clear guidance on when snapshots are included/excluded
   - Helpful suggestions for users experiencing token limits

Configuration options:
- CLI: --no-snapshots, --max-snapshot-tokens N, --differential-snapshots
- ENV: PLAYWRIGHT_MCP_INCLUDE_SNAPSHOTS, PLAYWRIGHT_MCP_MAX_SNAPSHOT_TOKENS, etc.
- Config file: includeSnapshots, maxSnapshotTokens, differentialSnapshots

Fixes token overflow errors while providing users full control over
snapshot behavior and response sizes.

## Playwright MCP
A Model Context Protocol (MCP) server that provides browser automation capabilities using [Playwright](https://playwright.dev). This server enables LLMs to interact with web pages through structured accessibility snapshots, bypassing the need for screenshots or visually-tuned models.
### Key Features
- **Fast and lightweight**. Uses Playwright's accessibility tree, not pixel-based input.
- **LLM-friendly**. No vision models needed, operates purely on structured data.
- **Deterministic tool application**. Avoids ambiguity common with screenshot-based approaches.
### Requirements
- Node.js 18 or newer
- VS Code, Cursor, Windsurf, Claude Desktop, Goose or any other MCP client
<!--
// Generate using:
node utils/generate-links.js
-->
### Getting started
First, install the Playwright MCP server with your client.
**Standard config** works in most of the tools:
```js
{
"mcpServers": {
"playwright": {
"command": "npx",
"args": [
"@playwright/mcp@latest"
]
}
}
}
```

<!--- End of options generated section -->
### User profile
You can run Playwright MCP with persistent profile like a regular browser (default), or in the isolated contexts for the testing sessions.
**Persistent profile**
All the logged in information will be stored in the persistent profile, you can delete it between sessions if you'd like to clear the offline state.
Persistent profile is located at the following locations and you can override it with the `--user-data-dir` argument.
```bash
# Windows
%USERPROFILE%\AppData\Local\ms-playwright\mcp-{channel}-profile
# macOS
- ~/Library/Caches/ms-playwright/mcp-{channel}-profile
# Linux
- ~/.cache/ms-playwright/mcp-{channel}-profile
```
**Isolated**
In the isolated mode, each session is started in the isolated profile. Every time you ask MCP to close the browser,
the session is closed and all the storage state for this session is lost. You can provide initial storage state
to the browser via the config's `contextOptions` or via the `--storage-state` argument. Learn more about the storage
state [here](https://playwright.dev/docs/auth).
```js
{
"mcpServers": {
"playwright": {
"command": "npx",
"args": [
"@playwright/mcp@latest",
"--isolated",
"--storage-state={path/to/storage.json}"
]
}
}
}
```
### Configuration file
The Playwright MCP server can be configured using a JSON configuration file. You can specify the configuration file
using the `--config` command line option:
```bash
npx @playwright/mcp@latest --config path/to/config.json
```

### Centralized Artifact Storage
The Playwright MCP server supports centralized artifact storage for organizing all generated files (screenshots, videos, and PDFs) in session-specific directories with comprehensive logging.
#### Configuration
**Command Line Option:**
```bash
npx @playwright/mcp@latest --artifact-dir /path/to/artifacts
```
**Environment Variable:**
```bash
export PLAYWRIGHT_MCP_ARTIFACT_DIR="/path/to/artifacts"
npx @playwright/mcp@latest
```
**MCP Client Configuration:**
```js
{
"mcpServers": {
"playwright": {
"command": "npx",
"args": [
"@playwright/mcp@latest",
"--artifact-dir",
"./browser-artifacts"
]
}
}
}
```
#### Features
When artifact storage is enabled, the server provides:
- **Session Isolation**: Each MCP session gets its own subdirectory
- **Organized Storage**: All artifacts saved to `{artifact-dir}/{session-id}/`
- **Tool Call Logging**: Complete audit trail in `tool-calls.json`
- **Automatic Organization**: Videos saved to `videos/` subdirectory
#### Directory Structure
```
browser-artifacts/
└── mcp-session-abc123/
├── tool-calls.json # Complete log of all tool calls
├── page-2024-01-15T10-30-00.png # Screenshots
├── document.pdf # Generated PDFs
└── videos/
└── session-recording.webm # Video recordings
```
#### Tool Call Log Format
The `tool-calls.json` file contains detailed information about each operation:
```json
[
{
"timestamp": "2024-01-15T10:30:00.000Z",
"toolName": "browser_take_screenshot",
"parameters": {
"filename": "login-page.png"
},
"result": "success",
"artifactPath": "login-page.png"
},
{
"timestamp": "2024-01-15T10:31:15.000Z",
"toolName": "browser_start_recording",
"parameters": {
"filename": "user-journey"
},
"result": "success"
}
]
```
#### Per-Session Control
You can dynamically enable, disable, or configure artifact storage during a session using the `browser_configure_artifacts` tool:
**Check Current Status:**
```
browser_configure_artifacts
```
**Enable Artifact Storage:**
```json
{
"enabled": true,
"directory": "./my-artifacts"
}
```
**Disable Artifact Storage:**
```json
{
"enabled": false
}
```
**Custom Session ID:**
```json
{
"enabled": true,
"sessionId": "my-custom-session"
}
```
#### Compatibility
- **Backward Compatible**: When `--artifact-dir` is not specified, all tools work exactly as before
- **Dynamic Control**: Artifact storage can be enabled/disabled per session without server restart
- **Fallback Behavior**: If artifact storage fails, tools fall back to default output directory
- **No Breaking Changes**: Existing configurations continue to work unchanged
### Standalone MCP server
When running headed browser on system w/o display or from worker processes of the IDEs,
run the MCP server from environment with the DISPLAY and pass the `--port` flag to enable HTTP transport.
```bash
npx @playwright/mcp@latest --port 8931
```
And then in MCP client config, set the `url` to the HTTP endpoint:
```js
{
"mcpServers": {
"playwright": {
"url": "http://localhost:8931/mcp"
}
}
}
```
<details>
<summary><b>Docker</b></summary>
**NOTE:** The Docker implementation only supports headless chromium at the moment.
```js
{
"mcpServers": {
"playwright": {
"command": "docker",
"args": ["run", "-i", "--rm", "--init", "--pull=always", "mcr.microsoft.com/playwright/mcp"]
}
}
}
```
You can build the Docker image yourself.
```
docker build -t mcr.microsoft.com/playwright/mcp .
```
</details>
<details>
<summary><b>Programmatic usage</b></summary>
```js
import http from 'http';
import { createConnection } from '@playwright/mcp';
import { SSEServerTransport } from '@modelcontextprotocol/sdk/server/sse.js';
http.createServer(async (req, res) => {
// ...
// Creates a headless Playwright MCP server with SSE transport
const connection = await createConnection({ browser: { launchOptions: { headless: true } } });
const transport = new SSEServerTransport('/messages', res);
await connection.sever.connect(transport);
// ...
});
