PDF tools for the AI you already use

Ask Claude, Cursor, Codex or any MCP client to merge, split, compress, convert, OCR or sign a PDF, and it does the work with ConvertPDF. Runs on our own servers in the EU, with no third-party AI. Files are deleted within an hour.

ChatGPT and Claude: connect by signing in

No key to copy. Add ConvertPDF as a connector with this server URL, sign in to ConvertPDF when asked and press Allow:

https://convertpdf.io/mcp

• ChatGPT: Settings → Security and login → turn on Developer mode. Then Plugins → Add plugin → Create app → Create MCP App: name it ConvertPDF, add the icon below, paste the URL above, choose OAuth and Create, then Sign in with ConvertPDF. Then attach a PDF in a chat and ask, for example, “compress this with ConvertPDF”.
• Claude (claude.ai and Claude Desktop): Settings → Connectors → Add custom connector, paste the URL above and connect.

ChatGPT asks for an icon when you create the app: download the ConvertPDF icon (PNG, 256 px).

Menu names can shift a little between app versions. You can disconnect an app any time under My account → API and MCP.

Coding agents: use a key

1. Get a free key

Sign in (Google or an email code, no password), then create a key under My account → API and MCP. One key works for MCP and the REST API. The free plan includes 20 units a day; PDF to Word, Office and OCR use 5.

2. Add the server

Claude Code

claude mcp add --transport http convertpdf https://convertpdf.io/mcp --header "Authorization: Bearer cpdf_your_key"

Cursor, Windsurf and other JSON configs

Add this to the client's MCP configuration (for Cursor: ~/.cursor/mcp.json):

{
    "mcpServers": {
        "convertpdf": {
            "url": "https://convertpdf.io/mcp",
            "headers": {
                "Authorization": "Bearer cpdf_your_key"
            }
        }
    }
}

VS Code

In .vscode/mcp.json:

{
    "servers": {
        "convertpdf": {
            "type": "http",
            "url": "https://convertpdf.io/mcp",
            "headers": {
                "Authorization": "Bearer cpdf_your_key"
            }
        }
    }
}

Codex

In ~/.codex/config.toml:

[mcp_servers.convertpdf]
url = "https://convertpdf.io/mcp"
http_headers = { "Authorization" = "Bearer cpdf_your_key" }

The server speaks Streamable HTTP at https://convertpdf.io/mcp with a bearer key. Any client that supports remote MCP servers with custom headers works the same way.

Ask for what you need

• “Compress ~/Desktop/report.pdf with ConvertPDF and save it next to the original.”
• “Merge every PDF in this folder in name order into one file.”
• “Turn this scanned contract into an editable Word document, the text is in Slovenian.”
• “Split invoices.pdf into one file per page.”

In ChatGPT you simply attach the file. Coding agents (Claude Code, Cursor, Codex, VS Code) upload it themselves. Document contents never go into the conversation: files travel to private storage directly.
