Changes

Code Changes

Documentation

Registry Support

ScrapeGraphAI packages can now be published using:

1. PyPI (https://pypi.org - default):

   • Validates via PyPI JSON API
   • Checks for mcp-name: <server-name> in package README

2. Smithery (https://smithery.ai):

   • Validates via npm API (Smithery uses npm backend)
   • Checks for mcpName field in package.json

3. Direct npm (https://registry.npmjs.org):

   • Also supported as an alternative

Example Usage

PyPI:

{
  "registryType": "scrapegraphai",
  "registryBaseUrl": "https://pypi.org",
  "identifier": "web-scraper-mcp",
  "version": "1.0.0"
}

Smithery:

{
  "registryType": "scrapegraphai",
  "registryBaseUrl": "https://smithery.ai",
  "identifier": "@ScrapeGraphAI/scrapegraph-mcp",
  "version": "1.0.0"
}

Testing

The validator follows the same patterns as existing registry validators (npm, pypi, etc.) and includes proper error handling and validation logic.
