How to Use the UK Postbox MCP in Google ADK

Q: Can I use the Google ADK to list all mail items from UK Postbox?

Yes, you just call listmailitems. This tool pulls a complete record of every item associated with your virtual mailbox. The data is then available for processing within Vertex AI.

Q: How does Google ADK handle tracking parcels from UK Postbox?

You use listparcels to get a list, and then getparcel to get detailed status updates on individual packages. This works smoothly within your enterprise agent design.

You call sendletter. The agent takes care of formatting the recipient's details and content. This allows you to automate official correspondence without leaving your Google Cloud environment.

Q: Can I check the connectivity status of UK Postbox using Google ADK?

Absolutely. You call checkukpostboxstatus. Before running any major workflow, it's smart to confirm that the MCP Server connection is active and ready for use.

Perplexity

Bulk Mail Item Retrieval

The agent can pull large datasets of physical mail using `list_mail_items`. This output is perfect for feeding into BigQuery for later analysis. You get a complete inventory of what's in the box via UK Postbox.

Enterprise Parcel Tracking

Need to know every parcel? Call `list_parcels`. Since you're operating within Google Cloud, this data flows naturally into your existing infrastructure. You can then use the details from `get_parcel` for deeper analysis.

Sending Structured Correspondence

To send a letter, the agent uses `send_letter`. Because of Google ADK's long-context reasoning, it handles complex inputs—like recipient names and multiple addresses—and acts on behalf of your enterprise processes using UK Postbox.

Setup guide

Set up UK Postbox MCP in Google ADK

Prerequisites

Python 3.10+ installed
google-adk package (pip install google-adk)
Active Vinkius subscription with a valid endpoint token

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with UK Postbox tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="UK Postbox_agent",
    model="gemini-2.0-flash",
    instruction="You have access to UK Postbox tools via MCP.",
    tools=mcp_tools,
)
