MCP URL Format Converter

MCP URL Format Converter is an MCP server that fetches content from any web address and converts it into structured formats such as HTML, JSON, Markdown, or plain text. Built for developers, data analysts, and users of AI assistants like Claude for Desktop, it enables language models to ingest and examine web pages, API endpoints, raw files, XML feeds, and tabular CSV data through a standardized interface. The server connects directly to external web resources using Node.js libraries including Cheerio, Marked, Fast-XML-Parser, CSVtoJSON, and Turndown to process incoming payloads into clean, consumable output. It incorporates automatic source format detection to handle diverse media types without manual configuration. Security controls such as HTML sanitization via sanitize-html and parameter validation via Zod are applied to help mitigate cross-site scripting risks and malformed payloads. In addition to universal format conversion, the server records a query history resource that tracks recently fetched URLs alongside their timestamps, allowing downstream agents to inspect past requests and systematically retrieve content across heterogeneous web environments.
