How to Use the Cora Bank MCP in Google ADK

Q: Can I restrict which Cora Bank tools Google ADK can access?

Yes, you can use the toolnames filter when setting up your McpToolset. This lets you expose read-only tools like coralistinvoices while hiding payment tools like corasendpix from customer-facing agents.

Run Gemini enterprise agents with Google ADK to analyze Cora Bank cash flow and execute Pix transfers directly from BigQuery.

Run deep cash flow analysis with Gemini and Google ADK

The `cora_get_statement` tool brings raw Brazilian transaction histories directly into Gemini's massive one-million-token context window. This allows your Google ADK agent to process months of financial records in a single run, finding patterns that standard scripts miss. By feeding this data straight into your enterprise pipeline, you can run predictive cash flow models. The agent uses `cora_get_balance` to match current liquid assets against upcoming liabilities without manual exports.

Trigger Pix payouts from BigQuery using this MCP Server

The `cora_send_pix` tool executes instant outbound payments driven by your database triggers. Your Google ADK agent monitors BigQuery tables for approved vendor invoices, matches the amounts, and initiates the Pix transfer automatically. To keep your ledgers clean, the agent immediately calls `cora_list_payments` to verify the execution. This closes the loop between your Google Cloud data warehouse and your actual Brazilian bank account.

Automate invoice tracking with Vertex AI integrations

The `cora_create_invoice` tool generates official boletos and Pix QR codes whenever your CRM logs a new sale. The Google ADK agent builds the payload, calls the bank, and returns the payment details to your customer. If a client requests a change, the agent uses `cora_get_invoice` to inspect the status or `cora_cancel_invoice` to void the charge. All these actions run through the same secure endpoint, keeping your billing automated.

Setup guide

Set up Cora Bank 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 Cora Bank 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="Cora Bank_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Cora Bank tools via MCP.",
    tools=mcp_tools,
)
