How to Use the Censys MCP in Google ADK

Q: How do I load the Censys MCP Server into a Google ADK agent?

Install google-adk and create an McpToolset pointing to your hosted Censys URL. Pass this toolset into the tools parameter when initializing your Google ADK LlmAgent to let Gemini call the search functions.

Connect Censys search tools to your Google ADK agents using our managed MCP Server for deep infrastructure analysis with Gemini.

Perplexity

Analyze massive host datasets with Google ADK

The `search_hosts` tool queries global internet-connected infrastructure, letting your Google ADK agent ingest raw Censys port and protocol data directly into its million-token context window. This integration allows Gemini models to reason over massive host lists without hitting token limits. This setup lets your Google ADK agent cross-reference Censys host data with your existing enterprise tables in BigQuery. The agent can write SQL queries to join live Censys port scans with internal asset lists, identifying unmanaged cloud resources in minutes.

Inspect SSL certificates using MCP Server queries

The `search_certificates` tool queries global SSL/TLS certificates by issuer names and validity dates, allowing your Google ADK agent to perform deep cryptographic audits. Your agent runs these Censys queries to detect expired or weak certificates across your entire external perimeter. You expose this Censys capability by adding the MCP Server toolset to your Google ADK `LlmAgent` configuration. Gemini's reasoning capabilities then parse the Censys certificate fields to flag configurations that violate your corporate security policies.

Audit host details for specific IP addresses

The `get_host` tool retrieves active ports, service banners, and operating system details for any public IP, feeding raw Censys data to your Google ADK workflow. Your agent invokes this tool when a security alert flags an anomalous IP address in your Google Cloud environment. By feeding this raw Censys banner data into Vertex AI via the Google ADK, your agent can analyze complex protocol handshakes. This integration lets you automate the initial triage of suspicious external connections without manual terminal work.

Setup guide

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

Common questions about Censys MCP in Google ADK

Install `google-adk` and create an `McpToolset` pointing to your hosted Censys URL. Pass this toolset into the `tools` parameter when initializing your Google ADK `LlmAgent` to let Gemini call the search functions.

Yes, because the Google ADK integrates natively with Google Cloud, you can write an agent that retrieves Censys host details and writes them directly to a BigQuery table. This automates your security data pipeline without extra middleware.

Gemini can process millions of tokens, meaning your Google ADK agent can ingest thousands of Censys host records returned by `search_hosts` at once. It can find patterns, certificate chains, and open ports across your entire IP block in a single prompt.

You can use the optional tool name filter when setting up the Censys MCP Server parameters. This limits the exposed tools so the Google ADK agent can only call certificate searches, preventing unauthorized IP scanning.

Query parameters and service banner payloads pass through ephemeral memory inside the V8 sandbox. No Censys search history or port configurations are cached or stored on the hosting platform, keeping your target lists confidential.
