Authentication

Authentication

Local stdio Mode

Pass the API key through environment variables:

• OUTSCRAPER_API_KEY

Example:

{
  "mcpServers": {
    "outscraper": {
      "command": "npx",
      "args": ["-y", "outscraper-mcp"],
      "env": {
        "OUTSCRAPER_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

Hosted HTTP Mode

Enable:

set CLOUD_SERVICE=true

Then provide the API key via one of these headers:

• Authorization: Bearer <api-key>
• X-API-KEY: <api-key>
• X-OUTSCRAPER-API-KEY: <api-key>

Notes

• In local stdio mode, environment-based auth is expected.
• In hosted HTTP mode with CLOUD_SERVICE=true, request headers are used.
• Rotate exposed API keys if they have been shared or logged accidentally.
