How to Use the UK Postbox MCP in Cursor

Q: When using Cursor, how do I verify UK Postbox connectivity?

Simply include a function call for checkukpostboxstatus in your code block. The AI will run it and inject the 'API connected' status directly into your project context.

Q: If I use UK Postbox with Cursor, can my application list addresses?

Yep. You just call listaddresses. This tool populates a list of available forwarding destinations that you can then reference and write into your code's logic.

Write code that manages mail flow with Cursor and MCP Server tools.

Perplexity

Inject live letter sending into your codebase.

Instead of writing mock functions, you call the `send_letter` tool directly in Agent mode. You pass variables for recipient name, address, and content, and the AI generates working code using real API responses.

Get parcel data without leaving your editor.

You need to know if a shipment arrived? Call `list_parcels` first. Then, use the returned ID with `get_parcel`. The resulting JSON payload gets injected right into the file you're currently writing.

Process mail scans and updates records.

A new physical letter came in? Your code can call `request_scan` to start the process. After receiving a successful status, your script can then use `get_mail_scan` to pull the resulting data structure.

Setup guide

Set up UK Postbox MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the UK Postbox MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent UK Postbox transactions." If the MCP tools are loaded correctly, Cursor will call the UK Postbox tools automatically. You can also check Settings → MCP for a green status indicator.

Common questions about UK Postbox MCP in Cursor

Simply include a function call for `check_ukpostbox_status` in your code block. The AI will run it and inject the 'API connected' status directly into your project context.

Yep. You just call `list_addresses`. This tool populates a list of available forwarding destinations that you can then reference and write into your code's logic.

The server manages the full mailing lifecycle. While it doesn't validate street names like USPS, listing addresses via `list_addresses` ensures you use a registered and usable forwarding endpoint.

The tool retrieves the full metadata for one item. This structured output is returned as live API data, allowing your program to process it immediately without needing manual parsing.

The server touches and returns scanned content details, including the date and time associated with the scan request and the resulting file metadata.
