The primary manifest — the file an agent reads to learn what this artifact does.
Convert files between 690+ formats from any MCP client — image, video, audio, document, data, spreadsheet, font, ebook, and archive. Free, no API key, no signup.
Powered by ChangeThisFile.com. Conversions run on real engines (FFmpeg, LibreOffice, Calibre, 7-Zip, sharp, Ghostscript, fonttools, and more) and return a temporary signed download URL. Uploaded files are auto-deleted within 24 hours.
| Tool | Description |
|---|---|
convert_file | 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_conversions | List all supported conversion routes, optionally filtered by source_format (e.g. docx → see every format you can convert DOCX into). |
The server is hosted at https://changethisfile.com/mcp using streamable HTTP transport (MCP spec 2025-03-26). If your client supports remote MCP servers, point it straight at the endpoint:
{
"mcpServers": {
"changethisfile": {
"type": "streamable-http",
"url": "https://changethisfile.com/mcp"
}
}
}Claude Code:
claude mcp add --transport http changethisfile https://changethisfile.com/mcpFor clients that only speak stdio, this package bridges stdio ↔ the hosted endpoint:
{
"mcpServers": {
"changethisfile": {
"command": "npx",
"args": ["-y", "github:aadilr/changethisfile-mcp"]
}
}
}Or clone and run directly:
git clone https://github.com/aadilr/changethisfile-mcp.git
cd changethisfile-mcp
npm install
node index.jsThis repo doubles as an Agent Skill and Claude Code plugin.
Any skills-capable agent (Claude Code, Codex CLI, Cursor, Gemini CLI, Copilot, and more):
npx skills add aadilr/changethisfile-mcpClaude Code plugin (bundles the MCP server + the skill):
/plugin marketplace add aadilr/changethisfile-mcp
/plugin install changethisfile@changethisfileThe file-conversion skill prefers the MCP tools when connected and otherwise falls back to a bundled script (skills/file-conversion/scripts/convert.sh) that talks to the hosted endpoint over plain HTTPS — no MCP client required.
