ChangeThisFile — file conversion between 690+ formats (hosted Streamable HTTP + stdio) MCP Server のツール

Convert a file. Pass a publicly accessible `source_url` **or** `base64_content` (max ~5MB), plus a `target_format` (e.g. `pdf`, `mp3`, `json`). Source format is auto-detected from the URL/filename, or pass `source_format` explicitly. Returns a download URL valid for 1 hour.

List all supported conversion routes, optionally filtered by `source_format` (e.g. `docx` → see every format you can convert DOCX into).

概要

What is ChangeThisFile?

ChangeThisFile is a Model Context Protocol (MCP) server that converts files between 690+ formats (image, video, audio, document, data, font, ebook, archive) using a hosted endpoint. It is free, requires no API key or signup, and is designed for any MCP client.

How to use ChangeThisFile?

You can use the hosted remote endpoint (https://changethisfile.com/mcp) with streamable HTTP transport, or run a local stdio bridge via npx github:aadilr/changethisfile-mcp. It also works as a Claude Code plugin, an Agent Skill, or via Docker. Two tools are provided: convert_file (pass a source URL or base64 content and a target format) and list_conversions (list all supported routes).
