Stream ClinicalTrials.gov into Google ADK

Use `find_recruiting_trials` to feed enrollment data into your Google Cloud agent pipelines. It bridges the gap between public research and your private infrastructure. Your agent executes the search and pipes the output into your existing data processing tasks. You maintain control over how the agent handles these findings.

Retrieve specific trial records for Google ADK

The `get_trial_details` tool fetches full research records by NCT ID. It turns opaque identifiers into actionable data for your Gemini-powered agents. This integration allows your agent to hold long-context discussions about specific studies. You get the full trial history directly inside your Google environment.

Query the registry from Google ADK

Run `search_clinical_trials` to filter by phase or status across the entire registry. It gives your agent a direct line to current research data. Your agent acts on these search results without leaving the Google ADK ecosystem. You define the search criteria and the tool returns the registry matches.

Setup guide

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