How to Use the CrossRef Alternative MCP in Google ADK

Q: How do I set up CrossRef Alternative with Google ADK?

Install the SDK, initialize the McpToolset with your Vinkius HTTP endpoint, and pass it to your LlmAgent to register the MCP Server. Your Gemini agent will immediately gain access to tools like searchworks.

Connect 150M+ academic records to Google ADK to ground Gemini's long-context reasoning in real scientific metadata.

Ground Gemini reasoning with the CrossRef Alternative MCP Server

Running `search_works` and `get_work` through the Google ADK grounds Gemini's million-token reasoning in real, verified facts. Your agent can pull massive blocks of academic metadata to ground its reasoning. Instead of feeding the model outdated training data, your Google ADK agent runs live queries. It fetches precise publication dates and citation counts from CrossRef Alternative, injecting them straight into the Gemini context window for highly accurate synthesis.

Map research funding directly to BigQuery tables

Querying `search_funders` and `get_funder` through the Google ADK allows your agent to bridge the gap between internal databases and external realities. Your agent resolves messy funder names in your BigQuery tables to official CrossRef Alternative URIs. The agent takes the structured JSON output from these tools and writes clean, standardized funding profiles back to your enterprise warehouse. This eliminates manual data cleaning for academic grant tracking in Google Cloud.

Validate publisher compliance at scale

Calling `get_journal` and `get_publisher` through the Google ADK allows your agent to automate enterprise compliance checks on where researchers publish. Your Google ADK agent can check if target journals match your organization's open-access policies. By combining these tools with Vertex AI's reasoning, you can automate complex policy checks via the MCP protocol. The agent flags non-compliant papers before they are submitted, keeping your intellectual property safe.

Setup guide

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

Common questions about CrossRef Alternative MCP in Google ADK

Install the SDK, initialize the `McpToolset` with your Vinkius HTTP endpoint, and pass it to your `LlmAgent` to register the MCP Server. Your Gemini agent will immediately gain access to tools like `search_works`.

Absolutely. You can pass multiple toolsets to your Google ADK agent, allowing it to search academic works with `search_works` and write the results to BigQuery.

Gemini easily digests bulk academic data. Your Google ADK agent can run `get_works_by_doi_list` for dozens of papers, feeding all abstracts into the context window for a comprehensive literature review.

Yes, you can use the tool name filter in Google ADK. If you only need journal validation, you can expose `get_journal` and block search tools.

All requests to CrossRef Alternative go through Vinkius's secure, ephemeral V8 isolates using clean MCP transports. Your DOIs, search terms, and publisher queries are processed in memory and never written to disk.
