Use the MCP Server for Data Conversion in Claude Desktop

Need to parse legacy feeds? The `convert_xml_to_json` tool takes raw, massive XML—like SOAP or RSS files—and converts them into clean JSON. This process handles nested elements and attributes deterministically, so you don't get hallucinations. It’s perfect for when your AI client needs structured data it can actually use, not some vague guess.

Convert Data Types Directly in Claude Desktop

When the output is JSON but you need to send it somewhere that only accepts XML, just call `convert_json_to_xml`. You pass a standard JSON object string and get back perfectly formatted XML. It’s super reliable. This means your agent can build data payloads for external systems without you ever having to touch XSLT or manually format tags.

Handle Complex Data Structures with the MCP Server

The `convert_xml_to_json` function doesn't skip anything. It accurately handles complex stuff like CDATA sections and attributes inside XML, giving you a deterministic JSON structure. You get everything preserved. This makes it great for developers running local tools because the data fidelity is high, no matter how messy the original feed was.
