How to Use the Nifty Gateway (NFT Marketplace API) MCP in Google ADK

Q: How do I initialize the Nifty Gateway (NFT Marketplace API) tools within Google ADK?

You define a McpToolset using StreamableHttpServerParameters pointing to your Vinkius URL and pass it to your LlmAgent tools list. This lets your Gemini model invoke the marketplace API directly during chat sessions.

Q: Can I restrict my Google ADK agent to only use the public Nifty Gateway (NFT Marketplace API) endpoints?

Yes, you can use the toolnames parameter in your McpToolset configuration to expose only listcollections or getcollection. This prevents the agent from attempting to call private portfolio tools.

Connect Nifty Gateway to Google ADK to analyze massive NFT collections and run portfolio reports inside your Gemini workspace.

Deep portfolio analysis using Google ADK and Gemini

The `list_user_nifties` tool connects your enterprise Google ADK agent directly to a collector's wallet history. Because Gemini models handle massive context windows, your agent can pull thousands of owned assets and cross-reference them with historical pricing data stored in BigQuery. You initialize the toolset via this MCP server and pass it to your `LlmAgent`. The agent then runs complex reasoning loops over the retrieved portfolio, compiling tax reports or valuation summaries directly into your Google Cloud storage buckets.

Bulk collection ingestion for BigQuery pipelines

The `list_collections` and `list_nifties` tools feed raw marketplace metadata straight into your Gemini-powered analytical pipelines. By configuring this MCP toolset in Google ADK, your agent can ingest entire marketplace catalogs and write the structured JSON payloads directly to BigQuery tables. This setup lets you skip writing custom ETL pipelines for NFT data. Your agent autonomously handles the pagination for `list_nifties` and updates your enterprise databases whenever new collections drop on the platform.

Granular tool filtering for secure enterprise agents

The `get_nifty` and `get_collection` tools can be isolated using the Google ADK `tool_names` filter to restrict what your public agent can access. This ensures that external users can query public floor prices without exposing internal administrative tools. By passing a restricted tool list to your `LlmAgent`, you maintain a secure boundary on Google Cloud using this MCP setup. The agent retains full access to the safe public tools while running inside an isolated enterprise environment.

Setup guide

Set up Nifty Gateway (NFT Marketplace 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 Nifty Gateway (NFT Marketplace 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="Nifty Gateway (NFT Marketplace API)_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Nifty Gateway (NFT Marketplace API) tools via MCP.",
    tools=mcp_tools,
)

Common questions about Nifty Gateway (NFT Marketplace API) MCP in Google ADK

You define a `McpToolset` using `StreamableHttpServerParameters` pointing to your Vinkius URL and pass it to your `LlmAgent` tools list. This lets your Gemini model invoke the marketplace API directly during chat sessions.

Yes, you can use the `tool_names` parameter in your `McpToolset` configuration to expose only `list_collections` or `get_collection`. This prevents the agent from attempting to call private portfolio tools.

Gemini's million-token context window allows Google ADK to ingest the entire paginated output of `list_nifties` in a single run. The model analyzes thousands of marketplace listings simultaneously without running out of memory.

Yes, the framework supports both transport protocols. For production setups on Google Cloud, using the HTTP transport with your Vinkius endpoint token is recommended for low-latency connections.

Your credentials never leave your secure Google Cloud environment. When the agent calls `list_user_nifties` via the MCP server, Vinkius processes the request in an ephemeral sandbox, passing only the resulting NFT metadata back to your ADK pipeline.
