How to Use the Holded MCP in Google ADK

Q: Can Google ADK agents run complex multi-step Holded workflows?

Yes. Your agent can read a customer record via listcontacts, check their unpaid balances using listinvoices, and issue a credit note using listcreditnotes in a single run.

Perplexity

Map inventory to BigQuery with Google ADK

The `list_products` tool lets your agent pull active stock levels straight from Holded. When you run this on Google ADK, your agent can cross-reference physical inventory with SQL tables in BigQuery. This lets you build smart replenishment systems. Your agent checks stock, reads sales velocity, and drafts new purchase orders using `list_purchase_orders` when inventory runs low.

Analyze high-volume sales orders

The `list_sales_orders` tool provides a complete feed of your pending customer commitments. Gemini's massive context window in the Google ADK allows your agent to ingest thousands of orders at once to identify seasonal buying trends. You can feed historical quotes from `list_quotes` directly into the LLM context. The agent compares expected revenue against actual closed sales without needing external database syncs.

Centralize your Spanish accounting on Google Cloud

The `list_purchase_invoices` tool gives your enterprise agent immediate access to vendor billing data. Running this MCP Server on Google Cloud lets you automate your entire accounts payable pipeline. Your agent can read incoming PDF invoices, match them against `list_expenses`, and flag any double-billing errors automatically. It brings localized Spanish ERP data directly into your cloud infrastructure.

Setup guide

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