MiConvert MCP Server

Ask your assistant "Convert https://example.com/invoice.ofd to PDF" and it gets back a download link. The conversions run on MiConvert, the same engine as the website, including the formats most converters lack:

• 3D and CAD: STEP, IGES, FCStd, STL, OBJ, GLB/glTF, 3MF, PLY, DAE, FBX, DWG → DXF/PDF (STEP to STL)

• OFD, China's e-invoice and official document format, → PDF (OFD to PDF)

• Wwise WEM game audio → MP3/WAV/OGG (WEM to MP3)

• Images (HEIC, RAW, WebP, AVIF, TIFF, SVG...), documents (DOCX, XLSX, PPTX, PDF, EPUB, Markdown...), audio, video, archives and fonts

Connect

The endpoint is https://miconvert.com/mcp (Streamable HTTP, stateless, no authentication).

Claude

claude.ai and Claude Desktop: Settings → Connectors → Add custom connector, then paste the URL.

Claude Code:

claude mcp add --transport http miconvert https://miconvert.com/mcp

Or install this repository as a plugin:

/plugin marketplace add huuhuybn/miconvert-mcp
/plugin install miconvert@miconvert-mcp

ChatGPT

Settings → Apps & Connectors → Advanced settings → enable Developer mode, then create a connector with the URL. No authentication.

Gemini CLI

gemini extensions install https://github.com/huuhuybn/miconvert-mcp

or gemini mcp add --transport http miconvert https://miconvert.com/mcp.

Cursor, VS Code, Windsurf, Cline and other MCP clients

Add the server to the client's MCP config (.cursor/mcp.json, .vscode/mcp.json, cline_mcp_settings.json, ...):

{
  "mcpServers": {
    "miconvert": {
      "url": "https://miconvert.com/mcp"
    }
  }
}

VS Code's mcp.json uses "servers" instead of "mcpServers" and takes "type": "http".

A client that only speaks stdio can bridge with mcp-remote:

{
  "mcpServers": {
    "miconvert": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://miconvert.com/mcp"]
    }
  }
}

Limits

• The file must be reachable by URL. Assistants do not pass files you attach in a chat, or files on your computer, to MCP servers. Share a link (Google Drive "Anyone with the link", Dropbox, OneDrive, a GitHub raw URL, ...), or upload it on miconvert.com.

• One file of up to 50 MB per call.

• A shared hourly allowance per connection. Heavy users: the Marketplace API has paid tiers up to 200 MB.

• Download links expire after about 4 hours.

Privacy

Files are fetched only to convert them, and inputs and outputs are deleted automatically. No account, cookie or API key is involved. See the privacy policy and terms.
