Perplexity

Validate Google ADK agent responses

Your agent uses `validate_hallucination_grounding` to audit all claims against your source documents. It forces the agent to cite specific records from your knowledge base. This prevents the model from injecting fabricated facts during complex reasoning tasks. Every factual assertion requires a direct link to a verifiable document or data source.

Separate opinion from fact in Google ADK

The `validate_hallucination_grounding` tool forces your agent to categorize every statement. Facts must be independently verifiable, while subjective assessments are explicitly labeled as opinions. This structure prevents your agents from presenting guesses as objective truth. Your users get a clear view of the evidence supporting every conclusion.

Define knowledge boundaries for Google ADK

Your agent must state its knowledge limitations before answering. The `validate_hallucination_grounding` tool checks that the agent acknowledges training cutoffs or missing data access. This stops the agent from filling information gaps with plausible fiction. It creates a transparent relationship between the agent and the user regarding what it actually knows.

Setup guide

Set up Hallucination Detector Prover 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 Hallucination Detector Prover 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="Hallucination Detector Prover_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Hallucination Detector Prover tools via MCP.",
    tools=mcp_tools,
)

Common questions about Hallucination Detector Prover MCP in Google ADK

You instantiate the McpToolset with your server URL and pass it to your LlmAgent. The tool becomes available for the agent to use during its reasoning loop.

Yes, it works across large context windows. It helps manage the risk of hallucination that naturally occurs when models process millions of tokens.

The tool validates the output text generated by your agent. If your agent pulls data from BigQuery, you can use this tool to verify the accuracy of the final summary.

It performs a cross-reference check on the generated response. It flags inconsistencies between different claims before the agent sends the answer to the user.

The server runs in an ephemeral sandbox. It processes your text fragments for grounding checks without retaining logs of your proprietary enterprise data.
