LangChain MCP AdaptersとOllamaで、AWS MCP ServersのAWS Documentation MCP Serverを試す

これは、なにをしたくて書いたもの？

前に、LangChain MCP Adaptersを使ってMCPを試してみました。

この時はチュートリアルに習って簡単なMCPサーバーを作ってみましたが、今回はAWS MCP Serversを使ってみたいと思います。

AWS MCP Servers

AWS MCP ServersのWebサイトはこちら。

GitHub - awslabs/mcp: AWS MCP Servers — specialized MCP servers that bring AWS best practices directly to your development workflow

AWSによるブログエントリーはこちら。

Introducing AWS MCP Servers for code assistants (Part 1) | AWS Machine Learning Blog

AWS MCP Serversは、MCPが利用可能な場所ならどこでもAWSを最大限に活用できるように支援する特別なMCPサーバー
スイートであるとされています。

AWS Documentation MCP Serverはここで追加しています。

$ uv add awslabs.aws-documentation-mcp-server

LangChain MCP Adaptersを使い、作成したソースコードはこちら。

client.py

import asyncio
import sys

from mcp import ClientSession, StdioServerParameters
from mcp.client.stdio import stdio_client

from langchain_mcp_adapters.tools import load_mcp_tools
from langgraph.prebuilt import create_react_agent

from langchain_ollama import ChatOllama


async def run_client(question: str) -> None:
    model = ChatOllama(
        model="llama3.2:3b",
        temperature=0,
        base_url="http://localhost:11434",
    )

    server_params = StdioServerParameters(
        command="uv",
        args=["run", "awslabs.aws-documentation-mcp-server"],
    )

    async with stdio_client(server_params) as (read, write):
        async with ClientSession(read, write) as session:
            await session.initialize()

            tools = await load_mcp_tools(session)

            agent = create_react_agent(model, tools)
            agent_response = await agent.ainvoke({"messages": question})

            print(f"question: {question}")

            print()
            print("response:")
            print(agent_response)
            print()

            print("messages:")
            for message in agent_response["messages"]:
                print(f"  id: {message.id}")
                print("  content: ")
                print(f"    {message.content}")
                print()


if __name__ == "__main__":
    question = sys.argv[1]
    asyncio.run(run_client(question))

モデルはToolが使えるllama3.2:3bです。

    model = ChatOllama(
        model="llama3.2:3b",
        temperature=0,
        base_url="http://localhost:11434",
    )

また、コマンドライン引数で質問を受け付けるようにしていて、結果のメッセージはすべて標準出力に書き出すようにしています。

LangChain MCP AdaptersからAWS Documentation MCP Serverを使ってみる

では、LangChain MCP AdaptersからAWS Documentation MCP Serverを使ってみましょう。

AWS Documentation MCP Serverを単純に起動するなら、こうですね。

$ uv run awslabs.aws-documentation-mcp-server

AWS Documentation MCP Serverが実装しているToolは、read_documentation、search_documentation、recommendの
ようですね。

ドキュメントに書かれている例を質問してみましょう。
「https://docs.aws.amazon.com/AmazonS3/latest/userguide/bucketnamingrules.html ページのコンテンツを推奨してください」

$ uv run client.py 'recommend content for page https://docs.aws.amazon.com/AmazonS3/latest/userguide/bucketnamingrules.html'

結果。

Tool、recommendを使用していることが確認できます。

ちなみに、肝心の回答そのものはおかしなことになっています…。

それとrecommendは動かせたのですが、search_documentなどはうまく動かせませんでした…。

  content:
    Error: ToolException('Error executing tool search_documentation: 1 validation error for search_documentationArguments\nlimit\n  Input should be a valid integer [type=int_type, input_value=None, input_type=NoneType]\n    For further information visit https://errors.pydantic.dev/2.11/v/int_type')
 Please fix your mistakes.

まあ、今回は使ってみることが目的なので1パターン通せただけでもよしとしましょう。

おわりに

LangChain MCP AdaptersとOllamaでAWS MCP ServersのAWS Documentation MCP Serverを試してみました。

とりあえず使うだけなら簡単そうですが、Ollamaとモデルが選ぶToolによってはうまく動かなかったので苦労しました…。
再現性がなく、選ぶToolによっては動いたりしますからね。

とはいえ、自分の環境では速度的に使い続けるのにはちょっと厳しいので、こうやって確認する程度ですね。
