Fetch (MCP Reference Server)

One of the original MCP reference implementations and the smallest genuinely useful example of the protocol: a single tool takes a URL, converts the HTML to markdown and returns it, with a length limit and a starting offset so long pages can be read in chunks. No key, no account. Worth knowing that it can also reach private network addresses, which matters when the server sits next to internal services.
