# MCP Fetch

Model Context Protocol server for fetching web content with custom http proxy. This allows Claude Desktop (or any MCP client) to fetch web content and handle images appropriately.

</a>

This repository forks from the [@smithery/mcp-fetch](https://github.com/smithery-ai/mcp-fetch) and replaces the `node-fetch` implementation with the library [node-fetch-native](https://www.npmjs.com/package/node-fetch-native).

The server will use the `http_proxy` and `https_proxy` environment variables to route requests through the proxy server by default if they are set.
You also can set the `MCP_HTTP_PROXY` environment variable to use a different proxy server.

## Available Tools

- `fetch`: Retrieves URLs from the Internet and extracts their content as markdown. If images are found, their URLs will be included in the response.

**Image Processing Specifications:**

Only extract image urls from the article content, and append them to the tool result:

```json
{
  "params": {
    "url": "https://www.example.com/articles/123"
  },
  "response": {
    "content": [
      {
        "type": "text",
        "text": "Contents of https://www.example.com/articles/123:\nHere is the article content\n\nImages found in article:\n- https://www.example.com/1.jpg.webp\n- https://www.example.com/2.jpg.webp\n- https://www.example.com/3.webp"
      }
    ]
  }
}
```
