# BigQuery MCP Toolset Sample
|
|
|
|
## Introduction
|
|
|
|
This sample agent demonstrates using ADK's `McpToolset` to interact with
|
|
BigQuery's official MCP endpoint, allowing an agent to access and execute
|
|
tools by leveraging the Model Context Protocol (MCP). These tools include:
|
|
|
|
1. `list_dataset_ids`
|
|
|
|
Fetches BigQuery dataset ids present in a GCP project.
|
|
|
|
2. `get_dataset_info`
|
|
|
|
Fetches metadata about a BigQuery dataset.
|
|
|
|
3. `list_table_ids`
|
|
|
|
Fetches table ids present in a BigQuery dataset.
|
|
|
|
4. `get_table_info`
|
|
|
|
Fetches metadata about a BigQuery table.
|
|
|
|
5. `execute_sql`
|
|
|
|
Runs or dry-runs a SQL query in BigQuery.
|
|
|
|
## How to use
|
|
|
|
Set up your project and local authentication by following the guide
|
|
[Use the BigQuery remote MCP server](https://docs.cloud.google.com/bigquery/docs/use-bigquery-mcp).
|
|
This agent uses Application Default Credentials (ADC) to authenticate with the
|
|
BigQuery MCP endpoint.
|
|
|
|
Set up environment variables in your `.env` file for using
|
|
[Google AI Studio](https://google.github.io/adk-docs/get-started/quickstart/#gemini---google-ai-studio)
|
|
or
|
|
[Google Cloud Vertex AI](https://google.github.io/adk-docs/get-started/quickstart/#gemini---google-cloud-vertex-ai)
|
|
for the LLM service for your agent. For example, for using Google AI Studio you
|
|
would set:
|
|
|
|
- GOOGLE_GENAI_USE_ENTERPRISE=FALSE
|
|
- GOOGLE_API_KEY={your api key}
|
|
|
|
Then run the agent using `adk run .` or `adk web .` in this directory.
|
|
|
|
## Sample prompts
|
|
|
|
- which weather datasets exist in bigquery public data?
|
|
- tell me more about noaa_lightning
|
|
- which tables exist in the ml_datasets dataset?
|
|
- show more details about the penguins table
|
|
- compute penguins population per island.
