PDFGate MCP Server

Model Context Protocol (MCP) server for the PDFGate API. Enables AI assistants to generate PDFs, manage documents and handle e-signatures.

Installation

Add the following to your MCP client configuration:

{
  "mcpServers": {
    "pdfgate": {
      "command": "npx",
      "args": ["-y", "@pdfgate/mcp-server"],
      "env": {
        "PDFGATE_API_KEY": "your_api_key_here"
      }
    }
  }
}

Hosted server (remote)

If you prefer not to run anything locally, we also host the MCP server, so you can connect straight to it — no npx, no local process. Point any client that supports remote (Streamable HTTP) MCP servers at:

https://mcp.pdfgate.com/server

You can authenticate in two ways.

Option 1 — OAuth

For clients that support remote MCP servers with OAuth (such as Claude and ChatGPT), add the server by its URL alone and sign in through your browser. There is no key to copy or store: the client registers itself, sends you to the PDFGate dashboard to approve access, and receives a scoped token automatically.

{
  "mcpServers": {
    "pdfgate": {
      "type": "http",
      "url": "https://mcp.pdfgate.com/server"
    }
  }
}

Many clients let you add this from their UI instead of a config file — for example, in Claude: Settings → Connectors → Add custom connector, then enter the URL above. OAuth sessions run against your production account; for the sandbox, use an X-API-KEY with a test_ key.

Option 2 — API key

Pass your key in the X-API-KEY header:

{
  "mcpServers": {
    "pdfgate": {
      "type": "http",
      "url": "https://mcp.pdfgate.com/server",
      "headers": {
        "X-API-KEY": "your_api_key_here"
      }
    }
  }
}

live_ keys use production and test_ keys use the sandbox — the environment is selected automatically from the key.

The hosted server provides the full PDFGate toolset (PDF generation, processing, form fields, e-signatures and webhooks). The exact client config field names (e.g. type / transport, headers) may vary by MCP client.

Webhook Triggers

The server listens for incoming PDFGate events on port 3599 by default. To receive events:

1. Expose port 3599 to the internet (e.g. via ngrok)
2. Use the create_webhook tool to register your public URL

Supported events:

Received events are available via the pdfgate://events MCP resource and pushed to the client in real time.
