Windsurf + pdfmcp: setup guide

Add pdfmcp to Windsurf Cascade via mcp_config.json.

What you need: a free pdfmcp API key — sign in with your email (no password) and copy the key shown at first login. Then replace pdfmcp_live_YOUR_KEY in the config below.

Where it goes: ~/.codeium/windsurf/mcp_config.json (Windsurf → Settings → MCP also opens it)

{
  "mcpServers": {
    "pdfmcp": {
      "serverUrl": "https://mcp.pdfmcp.org/mcp",
      "headers": {
        "X-API-Key": "pdfmcp_live_YOUR_KEY"
      }
    }
  }
}

Steps

Get a free API key from the pdfmcp dashboard and replace pdfmcp_live_YOUR_KEY in the config.
Save the config and restart Windsurf (or refresh the MCP panel).
In Cascade, the pdfmcp tools show up in the MCP tools list.
Try: “Use pdfmcp to split this PDF by pages”.

Windsurf calls the remote-URL field “serverUrl” (not “url”) — the config above already uses the right name.

Troubleshooting

401 / unauthorized: the key header is missing or mistyped. The header name is exactly X-API-Key (Claude Code uses Authorization: Bearer … — both work).
Tools don't appear: fully restart the client after editing its config; most clients only load MCP servers at startup.
Server unreachable: check the public status page — and your network's outbound HTTPS to mcp.pdfmcp.org.
