How to Use the Nhost MCP in Google ADK

Q: How do I load Nhost MCP Server tools into Google ADK?

Run pip install google-adk and configure StreamableHttpServerParameters with your endpoint. Wrap it in an McpToolset and assign it to your LlmAgent.

Q: Can my Google ADK agent register new Nhost users?

It can. The agent executes signupemailpassword or signupotpemail to create accounts directly from your Gemini prompt sequence.

Q: How do I restrict the Nhost tools my Google ADK agent can see?

Use the toolnames filter when initializing the toolset. This prevents the agent from calling changeemail or resetpassword if it only needs read access.

Q: Does the MCP Server support anonymous sessions?

Yes. The agent triggers signinanonymous to create a temporary session. This works well for public-facing Vertex AI endpoints that require basic rate tracking.

Give your Google ADK agents direct control over the Nhost MCP Server inside your Gemini enterprise environment.

Nhost MCP Server Auth Flows

The Nhost MCP Server connects your Gemini agents directly to user authentication and session states. When you pass the `McpToolset` to your `LlmAgent`, it gains immediate access to `signin_passwordless_email` and `signup_otp_email`. This setup bridges your GCP infrastructure with external user data. Your agent authenticates a user, retrieves their profile via `get_user`, and correlates that identity with records already sitting in BigQuery.

Long-Context File Analysis

Gemini's massive context window pairs perfectly with Nhost bucket storage. An agent calls `get_file` to pull raw file contents straight into memory for deep analysis. You skip writing manual download scripts. The agent reads the file, extracts the required data points, and immediately turns around to push a new report back using `upload_file`.

Session State Management

Enterprise agents need to maintain access during long-running tasks. The toolset includes `refresh_token` and `signout` so the agent can manage its own lifecycle without human intervention. You restrict exposed endpoints using the optional `tool_names` filter in Google ADK. If an agent only needs to generate links, you limit it to `get_file_presigned_url` and block destructive actions like `delete_file`.

Setup guide

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

The tools require JSON Web Tokens for elevated actions. You must inject these tokens via secure environment variables rather than hardcoding them into the Gemini prompt context, ensuring the LLM never leaks the raw signature.
