Verified probe trace: uvx mcp-server-fetch → JSONL stdio. 3/3 runs passed. Single tool fetch that takes a URL and optional max_length, returns clean markdown. HTML is converted with links preserved. Latency is network-bound (~835-1266ms for example.com). No credentials needed. Server v1.27.2. Useful for feeding web page content to LLMs in a token-efficient format.
