How to Use the TzKT (Tezos Indexer & Explorer API) MCP in Google ADK

Q: How does Google ADK query account details using TzKT (Tezos Indexer & Explorer API)?

The agent calls getaccount to pull specific information on an address. This provides a quick, detailed profile of the Tezos account directly through the MCP Server.

Q: Can I find staking and delegation history with TzKT (Tezos Indexer & Explorer API) using Google ADK?

Yes. You'll use liststaking for general stakking operations, and the listdelegations tool lists specific delegation actions, giving you a full picture of governance.

Q: What is the best way to list token transfers with TzKT (Tezos Indexer & Explorer API) via Google ADK?

Use listtokentransfers. This tool handles listing both FA1.2 and FA2 tokens, which means your agent captures all types of asset movements.

Q: Does the MCP Server support advanced listing of transactions with TzKT (Tezos Indexer & Explorer API) using Google ADK?

It does. The listtransactions tool provides highly configurable filtering, letting you narrow down huge datasets to exactly what your enterprise agent needs.

Analyze Account Financials

Start by pulling granular details using `get_account`. For deeper dives, run `get_account_report` to get a complete JSON summary of activity. You can also use `list_token_balances` to check how many tokens an account holds. If you need to see historical financial movements, the `get_account_balance_history` tool tracks every balance change over time.

Manage and Audit Contracts

Need contract visibility? Use `list_contracts` to list smart contracts with filters. The MCP Server lets your agent retrieve the underlying code via `get_contract_code`. This is critical for auditing. Furthermore, you can check what data the contract has saved using `get_contract_storage`, or find out all its callable functions through `get_contract_entrypoints`.

Retrieve Blockchain History

To understand when things happened, use `list_blocks` to filter and list blocks. You can also get the current network state with `get_head`. For specific actions, `get_operations_by_hash` retrieves all operations linked to one transaction hash. Try `list_transactions` for advanced filtering across the entire history of transactions.

Setup guide

Set up TzKT (Tezos Indexer & Explorer API) 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 TzKT (Tezos Indexer & Explorer API) 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="TzKT (Tezos Indexer & Explorer API)_agent",
    model="gemini-2.0-flash",
    instruction="You have access to TzKT (Tezos Indexer & Explorer API) tools via MCP.",
    tools=mcp_tools,
)
