Extract Skill

Extract clean content from specific URLs. Ideal when you know which pages you want content from.

Authentication

The script uses OAuth via the Tavily MCP server. No manual setup required - on first run, it will:

Check for existing tokens in ~/.mcp-auth/
If none found, automatically open your browser for OAuth authentication

Note: You must have an existing Tavily account. The OAuth flow only supports login — account creation is not available through this flow. Sign up at tavily.com first if you don't have an account.

Alternative: API Key

If you prefer using an API key, get one at https://tavily.com and add to ~/.claude/settings.json:

{
  "env": {
    "TAVILY_API_KEY": "tvly-your-api-key-here"
  }
}

Quick Start

Using the Script

./scripts/extract.sh '<json>'

Examples:

# Single URL
./scripts/extract.sh '{"urls": ["https://example.com/article"]}'

# Multiple URLs
./scripts/extract.sh '{"urls": ["https://example.com/page1", "https://example.com/page2"]}'

# With query focus and chunks
./scripts/extract.sh '{"urls": ["https://example.com/docs"], "query": "authentication API", "chunks_per_source": 3}'

# Advanced extraction for JS pages
./scripts/extract.sh '{"urls": ["https://app.example.com"], "extract_depth": "advanced", "timeout": 60}'

Basic Extraction

curl --request POST \

  --header 'Content-Type: application/json' \
  --data '{

      "https://example.com/page2",
      "https://example.com/page3",
      "https://example.com/page4",
      "https://example.com/page5"
    ],
    "extract_depth": "basic"
  }'

Tips

Max 20 URLs per request - batch larger lists
Use query + chunks_per_source to get only relevant content
Try basic first, fall back to advanced if content is missing
Set longer timeout for slow pages (up to 60s)
Check failed_results for URLs that couldn't be extracted
