NPX-based MCPs (most common)

{
  "mcp-name": {
    "command": "cmd",
    "args": ["/c", "npx", "-y", "@package/name"]
  }
}

UVX-based MCPs (Python)

{
  "mcp-name": {
    "command": "cmd",
    "args": ["/c", "uvx", "package-name"]
  }
}

With Environment Variables

Fast Playwright Token Optimization

Fast Playwright reduces token usage by 70-90% compared to vanilla Microsoft version.

Why Fast Playwright?

Feature	Vanilla	Fast
Tokens/snapshot	~12k	~2-3k
Batch execute	❌	✅
Diff mode	❌	✅
Snapshot selector	Basic	Fine-grained

Optimization Patterns

Pattern 1: Batch Execute (90% reduction)

{
  "name": "browser_batch_execute",
  "arguments": {
    "steps": [
      {"tool": "browser_navigate", "arguments": {"url": "https://example.com"}},
      {"tool": "browser_type", "arguments": {"selectors": [{"css": "#search"}], "text": "query"}},
      {"tool": "browser_click", "arguments": {"selectors": [{"css": "#submit"}]}}
    ],
    "globalExpectation": {"includeSnapshot": false, "includeConsole": false}
  }
}

Pattern 2: Targeted Snapshots

{"expectation": {"snapshotOptions": {"selector": ".product-list"}, "includeConsole": false}}

Pattern 3: Diff Mode

{"expectation": {"diffOptions": {"enabled": true, "format": "minimal"}}}
