前提条件
- システムに Python がインストールされている必要があります。
- システムに
pipがインストールされている必要があります。 - Anthropic の API キー、または他の LLM プロバイダーの API キーが必要です
1
ライブラリをインストールする
次のコマンドを実行して Agno ライブラリをインストールします。
pip install -q --upgrade pip
pip install -q agno
pip install -q ipywidgets
2
認証情報を設定する
次に、Anthropic API key を指定する必要があります。次に、ClickHouse SQL playgroundへの接続に必要な認証情報を定義します。
import os, getpass
os.environ["ANTHROPIC_API_KEY"] = getpass.getpass("Enter Anthropic API Key:")
Response
Enter Anthropic API Key: ········
別のLLMプロバイダーを使用するAnthropic API keyをお持ちでなく、別のLLMプロバイダーを使用したい場合は、
Agno docsで認証情報の設定手順を確認できます
env = {
"CLICKHOUSE_HOST": "sql-clickhouse.clickhouse.com",
"CLICKHOUSE_PORT": "8443",
"CLICKHOUSE_USER": "demo",
"CLICKHOUSE_PASSWORD": "",
"CLICKHOUSE_SECURE": "true"
}

MCPサーバーとAgnoエージェントを初期化する
次に、ClickHouse MCPサーバーがClickHouse SQL playgroundを参照するように設定し、
Agnoエージェントを初期化して、実際に質問してみましょう。
from agno.agent import Agent
from agno.tools.mcp import MCPTools
from agno.models.anthropic import Claude
async with MCPTools(command="uv run --with mcp-clickhouse --python 3.13 mcp-clickhouse", env=env, timeout_seconds=60) as mcp_tools:
agent = Agent(
model=Claude(id="claude-3-5-sonnet-20240620"),
markdown=True,
tools = [mcp_tools]
)
await agent.aprint_response("What's the most starred project in 2025?", stream=True)

┃ To answer your question about the most starred project in 2025, I'll need to query the ClickHouse database. ┃
┃ However, before I can do that, I need to gather some information and make sure we're looking at the right data. ┃
┃ Let me check the available databases and tables first.Thank you for providing the list of databases. I can see ┃
┃ that there's a "github" database, which is likely to contain the information we're looking for. Let's check the ┃
┃ tables in this database.Now that we have information about the tables in the github database, we can query the ┃
┃ relevant data to answer your question about the most starred project in 2025. We'll use the repo_events_per_day ┃
┃ table, which contains daily event counts for each repository, including star events (WatchEvents). ┃
┃ ┃
┃ Let's create a query to find the most starred project in 2025:Based on the query results, I can answer your ┃
┃ question about the most starred project in 2025: ┃
┃ ┃
┃ The most starred project in 2025 was deepseek-ai/DeepSeek-R1, which received 84,962 stars during that year. ┃
┃ ┃
┃ This project, DeepSeek-R1, appears to be an AI-related repository from the DeepSeek AI organization. It gained ┃
┃ significant attention and popularity among the GitHub community in 2025, earning the highest number of stars ┃
┃ for any project during that year. ┃
┃ ┃
┃ It's worth noting that this data is based on the GitHub events recorded in the database, and it represents the ┃
┃ stars (WatchEvents) accumulated specifically during the year 2025. The total number of stars for this project ┃
┃ might be higher if we consider its entire lifespan. ┃
