How to Use the Gnosisscan (Gnosis Chain Explorer) MCP in Google ADK

Q: Can Google ADK filter which Gnosisscan (Gnosis Chain Explorer) tools are exposed?

Yes, you can use the toolnames filter parameter in the McpToolset configuration. This restricts your Gemini agent to only the specific endpoints it needs, like getaccountbalance.

Q: How does Google ADK handle Gnosisscan (Gnosis Chain Explorer) block countdowns?

Your agent calls getblockcountdown with the target block number. This returns the estimated remaining time, allowing your agent to pause workflows until a specific block is mined.

Q: Can I use this server to read raw contract bytecode?

Yes. Your agent uses proxygetcode to retrieve the deployed runtime bytecode of any contract address on Gnosis Chain.

Connect your Google ADK agents directly to Gnosis Chain to feed live block data into your Vertex AI pipelines.

Feed real-time event logs into Google ADK pipelines

The `get_logs` tool pulls specific event signatures directly from Gnosis Chain blocks. Your Gemini agent parses these logs to trigger backend workflows or store clean transaction records in BigQuery. To narrow down the search window, your agent uses `get_block_bytime` to find the exact block number associated with a timestamp. This keeps your data pipelines efficient by avoiding broad, wasteful scans over the entire chain history.

Track GNO token pricing inside Google ADK workflows

The `get_stats_gnoprice` tool retrieves the live price of GNO and xDAI directly from the explorer. Your agent uses these real-time price feeds to calculate portfolio valuations or adjust trading thresholds on the fly. For network-wide metrics, the agent queries `get_stats_ethsupply` to monitor the total supply of xDAI. This lets your analytical models factor in network liquidity changes as they happen.

Run direct RPC queries via the Gnosisscan MCP Server

The `proxy_getstorageat` tool reads raw storage slots on Gnosis Chain contracts. Your agent uses this low-level access to verify internal contract state that isn't exposed by standard public functions. If the agent needs to inspect a specific block, it invokes `proxy_getblockbynumber` to pull the full header and transaction list. This provides a complete snapshot of chain activity for your enterprise analytical models.

Setup guide

Set up Gnosisscan (Gnosis Chain Explorer) 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 Gnosisscan (Gnosis Chain Explorer) 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="Gnosisscan (Gnosis Chain Explorer)_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Gnosisscan (Gnosis Chain Explorer) tools via MCP.",
    tools=mcp_tools,
)

Common questions about Gnosisscan (Gnosis Chain Explorer) MCP in Google ADK

You initialize the tools using the McpToolset class with the Gnosisscan server URL. Pass this toolset directly to your LlmAgent instance to expose the blockchain endpoints.

Yes, you can use the tool_names filter parameter in the McpToolset configuration. This restricts your Gemini agent to only the specific endpoints it needs, like `get_account_balance`.

Your agent calls `get_block_countdown` with the target block number. This returns the estimated remaining time, allowing your agent to pause workflows until a specific block is mined.

Yes. Your agent uses `proxy_getcode` to retrieve the deployed runtime bytecode of any contract address on Gnosis Chain.

No. The server only receives public blockchain parameters like contract ABIs and event logs to perform queries. Your Google Cloud credentials, BigQuery datasets, and Vertex AI models remain completely isolated.
