How to Use the Corpay One MCP in Google ADK

Q: How do I initialize Corpay One inside my Google ADK agent?

Install the Google ADK, construct an McpToolset with the HTTP server parameters, and pass it to your LlmAgent. The Gemini model will immediately see the seven financial tools exposed by the MCP Server.

Q: Does Corpay One support tool filtering in Google ADK?

Yes, you can use the toolnames parameter in your ADK setup to restrict access. This lets you expose read-only tools like listpayments while hiding write operations.

Q: Can I query Corpay One payment details using Google ADK?

Yes, the agent calls getpaymentdetails to pull specific transaction histories. You can combine this with Vertex AI to run predictive cash flow modeling.

Run automated financial audits by linking Corpay One tools to Gemini's long-context window using Google ADK.

Perplexity

Enterprise AP Pipeline via Google ADK

The `list_financial_documents` tool pulls historical invoice data directly into Gemini's massive context window using this MCP Server. This allows your Google ADK agent to analyze months of billing history in a single execution pass. You can run complex cross-referencing jobs against your BigQuery datasets without hitting token limits. The agent checks every record, flagging anomalies that standard heuristic parsers miss entirely.

Automated Invoice Ingestion

The `create_new_document` tool pushes raw invoice files straight into your accounts payable queue via MCP. Your enterprise agent handles OCR extraction on Google Cloud, then drops the validated document into your billing pipeline. After uploading, the agent uses `get_document_details` to verify that the metadata matches your cloud-stored purchase orders. This keeps your records synchronized across your ERP and your storage buckets.

Vendor and Payment Verification

The `list_payments` tool retrieves your entire payment history to verify matching transactions. Your agent maps these records against active vendor files to ensure no bill is paid twice. By querying `list_account_vendors`, the agent confirms that the recipient exists in your system. This simple check blocks unapproved payments before they leave your bank account.

Setup guide

Set up Corpay One 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 Corpay One 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="Corpay One_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Corpay One tools via MCP.",
    tools=mcp_tools,
)
