How to Use the EPO Open Patent Services MCP in Google ADK

Q: How do I integrate EPO Open Patent Services into my Google ADK agent?

You instantiate an McpToolset with the server URL from Vinkius and pass it to your LlmAgent. The ADK handles discovering tools like searchepopatents automatically. It's a single line of code to get connected.

Q: Can I filter which tools my agent sees?

Yes, the McpToolset in Google ADK accepts a toolnames filter. You could expose only searchepopatents to a discovery agent, and getpatentbibliographic to a separate analysis agent for better control.

Q: How can I use Google ADK to monitor competitor patents with EPO Open Patent Services?

Create an agent that runs a scheduled job. The agent uses searchepopatents with a CQL query for a competitor's name. It then compares the results to a list of known patents in BigQuery to identify new filings.

Q: What's the best way to handle large result sets from EPO Open Patent Services in Google ADK?

Use your agent as a controller. Have it run the searchepopatents query, then iterate through the patent IDs. For each ID, it can call getpatentbibliographic and pipe the structured output directly into a BigQuery table for large-scale analysis.

Connect Google ADK agents to the EPO patent database. Analyze IP at scale and integrate findings directly into your Google Cloud workflow.

Query EPO Data from Google ADK

Use the `search_epo_patents` tool to execute targeted patent searches from your Gemini-powered agent. You can build scripts to automate competitive intelligence gathering or prior art analysis. The results feed right back into your agent's context. This is built for enterprise workflows. You can have your agent run a search, get patent IDs, then use other tools to pull the full text and summarize it with a long-context model. It connects your Google Cloud environment to the world's patent data.

Extract and Stage Patent Data

The `get_patent_bibliographic` and `get_patent_legal_status` tools are your agent's way to pull raw data for analysis. Give your agent a patent number, and it gets back structured metadata and the current legal status. The real value here is for Google Cloud users. Your Google ADK agent, connected via this MCP, can fetch this data and then use other tools to write it directly into a BigQuery table. You can build a pipeline that keeps your internal IP database in sync with the EPO.

Verify EPO Service Health

Before running a large batch of queries, your agent can use the `check_api_status` tool. It confirms the EPO's own API is operational. This prevents wasting time and API calls on a service that's temporarily down. It's a simple, necessary check for any serious data pipeline. In a Google ADK setup, you can log the status checks to Cloud Logging, giving you a complete audit trail of your data ingestion process. This MCP server handles the connection for you.

Setup guide

Set up EPO Open Patent Services 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 EPO Open Patent Services 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="EPO Open Patent Services_agent",
    model="gemini-2.0-flash",
    instruction="You have access to EPO Open Patent Services tools via MCP.",
    tools=mcp_tools,
)
