v0.4.13

**A new update bringing feed spiders and a smarter MCP server 🎉**

## 🚀 New Stuff and quality of life changes

- **New feed spider templates**. `XMLFeedSpider` iterates over the nodes of any XML feed (RSS, Atom, product feeds, etc.), and `CSVFeedSpider` iterates over CSV rows as dictionaries. Both decompress gzipped feeds automatically. (Check the [docs](https://scrapling.readthedocs.io/en/latest/spiders/generic-templates.html))
  ```python
  from scrapling.spiders import XMLFeedSpider

  class RSSSpider(XMLFeedSpider):
      name = "rss"
      start_urls = ["https://example.com/feed.xml"]

      async def parse_node(self, response, node):
          yield {"title": node.findtext("title"), "link": node.findtext("link")}

  result = RSSSpider().start()
  ```
- **Upgraded the MCP server to MCP SDK v2 and made it smarter**. The server now ships instructions that teach your AI agent how to use the tools efficiently; every tool declares annotations so clients like Claude Code can auto-approve the read-only ones; tool descriptions are leaner to save tokens; and the server advertises its version and logo to MCP clients. (Check the [docs](https://scrapling.readthedocs.io/en/latest/ai/mcp-server.html))
- **Added a `scrapling-mcp` command** that maps directly to `scrapling mcp`, so registering Scrapling with MCP clients and registries that expect a single command is now a one-liner.
- **Unpinned Playwright/Patchright and browser versions**. The generated browser User-Agent now always matches the exact Chromium version your installed Playwright/Patchright drives, so Scrapling no longer pins their versions and you can upgrade them freely. Run `scrapling install --force` after updating to refresh the browsers.

## 🐛 Bug Fixes

- **Fixed importing Scrapling crashing with a `browserforge` ValueError** when the fingerprints data package lags behind the browser versions. (Fixes [#394](https://github.com/D4Vinci/Scrapling/issues/394), [#396](https://github.com/D4Vinci/Scrapling/issues/396), and [#400](https://github.com/D4Vinci/Scrapling/issues/400))
- **Fixed the MCP bulk browser tools mis-sizing their page pools**, which made `bulk_fetch` fail on batches of more than 50 URLs and `bulk_stealthy_fetch` fetch all URLs through a single tab, by @Yigtwxx in [#393](https://github.com/D4Vinci/Scrapling/pull/393).

## Project

- **New [AI Contribution Policy](https://github.com/D4Vinci/Scrapling/blob/main/AI_POLICY.md)**: AI-assisted contributions are welcome but must be disclosed in the PR or issue; submissions that look like undisclosed AI output get labeled and closed.

_🙏 Special thanks to the community for all the continuous testing and feedback_
