How to Use the EPO Open Patent Services MCP in Cursor

Q: How do I configure the EPO Open Patent Services MCP Server in Cursor?

Add the server details to your .cursor/mcp.json file in your project root. Once configured, your Cursor agent can call the patent search and lookup tools during active coding sessions.

Q: How does Cursor use the EPO Open Patent Services to write tests?

The agent calls getpatentbibliographic to fetch an actual patent payload, then uses that live JSON structure to generate mock data and unit tests.

Q: What happens if the EPO API goes offline?

The checkapistatus tool lets your agent verify the endpoint availability. If the EPO servers are down, the MCP Server returns the error state so your code can handle it gracefully.

Run live patent database queries and write code using real EPO metadata directly inside Cursor.

Generate code with live patent data in Cursor

The `search_epo_patents` tool injects real-world patent search results directly into your active code editor. Your agent runs the query, grabs the document IDs, and writes your parsing scripts using live data instead of static stubs. This keeps your development cycle grounded in reality. Using this MCP Server inside Cursor means you don't have to guess the JSON structure of the EPO response. Your agent inspects the actual payload returned by the server and writes accurate TypeScript interfaces on the fly.

Retrieve bibliographic records during development

The `get_patent_bibliographic` tool pulls full metadata schemas for any patent document directly into your workspace. Your agent uses this tool to populate local databases or test suites with authentic registry records. You avoid the hassle of downloading manual XML dumps. This direct integration allows you to build data pipelines faster. The agent reads the output of the tool, maps the fields to your database schema, and writes the migration code in one step.

Verify legal status inside your editor

The `get_patent_legal_status` tool fetches the live legal history of any patent application without leaving your code. Your agent checks this data to verify your application's compliance logic against real-world registry changes. You can use `check_api_status` to debug connection issues directly from the Cursor terminal. It tells you instantly if a failed test is due to your code or an EPO service outage.

Setup guide

Set up EPO Open Patent Services MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the EPO Open Patent Services MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent EPO Open Patent Services transactions." If the MCP tools are loaded correctly, Cursor will call the EPO Open Patent Services tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "epo-open-patent-services-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }

Common questions about EPO Open Patent Services MCP in Cursor

Add the server details to your `.cursor/mcp.json` file in your project root. Once configured, your Cursor agent can call the patent search and lookup tools during active coding sessions.

Yes. You can instruct the Cursor agent to loop through a list of document IDs and call `get_patent_bibliographic` via the MCP Server to build a local dataset.

The agent calls `get_patent_bibliographic` to fetch an actual patent payload, then uses that live JSON structure to generate mock data and unit tests.

The `check_api_status` tool lets your agent verify the endpoint availability. If the EPO servers are down, the MCP Server returns the error state so your code can handle it gracefully.

Your patent application numbers and search terms are transmitted directly to the EPO servers via encrypted TLS connections. No search history or retrieved bibliographic data is cached on external middleware.
