How to Use the Alpaca Trading MCP in Google ADK

Q: How do I initialize Alpaca Trading with Google ADK?

Install google-adk and configure McpToolset with your Vinkius URL. Pass that toolset to your LlmAgent instance. You can use the toolnames filter if you only want to expose specific read-only tools.

Q: Can Gemini read my current portfolio balance?

Calling getbrokeraccount fetches your exact account ID and current status. The agent reads your buying power before deciding how many shares it can afford.

Q: What is the fastest way to get live pricing?

Your agent invokes getlateststockstrades to see the most recent executed transactions. It provides immediate feedback on where the market is actually clearing, rather than just the quoted spread.

Connect Alpaca Trading to Google ADK and let Gemini agents execute trades based on BigQuery market analysis.

Perplexity

Feed years of market data into Gemini

Running `get_stocks_bars` pulls historical price action directly into your agent's memory. You request specific timeframes for equities, and the tool returns the open, high, low, and close data. Gemini models hold millions of tokens. You can dump months of minute-by-minute trading bars into the context window, cross-reference it with your internal BigQuery datasets, and let the agent spot long-term patterns.

Trade crypto pairs through Google ADK

The `get_crypto_bars` tool fetches historical cryptocurrency pricing for your agent to analyze. Once the model decides on an entry point, it calls `create_order` to execute the digital asset purchase. Connecting this to Google Cloud infrastructure means your trading logic runs right next to your data warehouse. The agent watches the crypto markets and triggers buy orders without leaving your VPC.

Provision accounts via this MCP Server

Firing `create_broker_account` generates a fresh trading profile complete with identity and disclosure objects. The tool handles the heavy lifting of user onboarding directly through the protocol. Enterprise setups often require strict access controls. You can use the `issue_token` tool to generate OAuth2 credentials for machine-to-machine authentication, keeping your automated trading systems secure.

Setup guide

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