FastMCPとLangChainを使用したMCP（モデルコンテキストプロトコル）サーバーとクライアント
この例では、 FastMCPを使用してローカルMCPサーバーを構築し、MCP サーバーで定義されたツールを使用する LangChain 人工知能エージェントを作成します。
MCPサーバーの作成には通常、大量の定型コードと設定が必要です。FastMCPを使用すると、MCPサーバーのセットアップが大幅に簡素化されます。
LangChain MCP アダプターは、ローカルまたは外部の MCP サーバーに簡単に接続できます。
この例では、FastMCPを使用してローカルMCPサーバーを作成し、クライアント側でLangChain MCPアダプターを使用します。この例ではOpenAI Large Language Model（LLM）を使用しているため、LLMとの通信にはLangChainのOpenAI実装も使用します。LangGraph ReAct（推論と行動）エージェントを作成します。非同期関数にはasyncioが必要です。
この例ではローカルのMCPサーバーを使用しているため、接続（「トランスポート」）にはstdio（Pythonの標準入出力ストリーム）が使用されます。外部のMCPサーバーでは、stdioの代わりにServer-Sent Events（SSE）またはWebSocketトランスポートが必要になります。
LLMは株式に関するあらゆる質問をすることができます。LLMはMCPサーバーに定義されたツールを呼び出し、すべての情報を収集し、収集した情報に基づいて回答します。
この例では次のことが問われます。
What company uses the stock ticker META and how did this company's revenue develop over the last quarters and years?YFinanceは、MCPサーバー向けの株式市場ツールを提供します。YFinanceは、Yahoo Financeの金融データにアクセスするためのPythonライブラリです。YFinanceはAPIキーを必要としません。
この例に必要なAPIキー
この例ではOpenAI APIキーが必要です。OpenAI APIキーはここから取得できます。OpenAI APIキーを.env.exampleファイルに挿入し、ファイル名を.envに変更してください（末尾の「.example」を削除してください）。

Financial data MCP server for Claude, ChatGPT, Cursor and Codex. Real-time stock quotes, financial statements, options flow, SEC filings, insider trades, 13F holdings, macro data and market news from gloom.sh, the open-source Bloomberg Terminal alternative.
Your agent needs markets — prices and fundamentals for listed companies, the filings behind them, crypto, and what the prediction markets put the odds at. **What you can ask for** • "Pull this company's income statement, cash flow and balance sheet for the last 8 quarters." • "What did insiders buy or sell, and when?" • "Snapshot prices for these 50 tickers, then the OHLC history for the three that moved." • "What are the current odds on this event across Kalshi and Polymarket?" • "Screen for companies matching these financial criteria." **How to use it** Point any MCP client at https://mcp.aisa.one/finance/mcp and sign in with OAuth — there is no key to create or paste. 49 tools: prices and snapshots, income statements, balance sheets and cash flows, metrics and ratios, earnings and analyst estimates, filings and line-item search, insider trades, macro interest rates, news, a screener; CoinGecko spot prices, market tables, OHLC, per-venue tickers and trending; Kalshi and Polymarket markets and trades; plus EDINET filings for Japan. **Why this rather than the source** Equities, crypto and event markets behind one account, so a cross-asset question is one conversation. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Read the number here, then ask the same agent what X is saying about the ticker today — without adding a second server. **What it costs** Finding and inspecting an operation is free. Running one is billed per call at API prices, with no seat and no monthly minimum, and every call takes max_price_usd so an agent cannot overspend by accident. **Where else it reaches** https://mcp.aisa.one/marketpulse/mcp · /crypto-market-data/mcp · /prediction-market-data/mcp · /stock-pulse/mcp for one slice each.
MCP server giving AI agents one-connection access to China A-share market intelligence: financials,
Your agent needs company financials it can compute on — statements, ratios, earnings, estimates, filings and insider activity as structured data, not a PDF. **What you can ask for** • "Give me 8 quarters of income statement, balance sheet and cash flow for this ticker." • "What do analysts estimate for next quarter, and how did the last four surprise?" • "Find this exact line item across every filing." • "Who bought or sold as an insider in the last 90 days?" • "Screen for profitable companies under this valuation with growing revenue." **How to use it** Point any MCP client at https://mcp.aisa.one/marketpulse/mcp and sign in with OAuth — there is no key to create or paste. 21 tools: prices and snapshots, income statements, balance sheets, cash-flow statements, financial metrics and snapshots, earnings, analyst estimates, company facts, filings and filing items, line-item search, a screener, insider trades, macro interest rates, news, plus EDINET documents and filing digests for Japanese issuers. **Why this rather than the source** Statements as fields you can compute on, and a screener in the same place. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Read the fundamentals here, then ask the same agent what social is saying about the ticker — without adding a second server. **What it costs** Finding and inspecting an operation is free. Running one is billed per call at API prices, with no seat and no monthly minimum, and every call takes max_price_usd so an agent cannot overspend by accident. **Where else it reaches** https://mcp.aisa.one/finance/mcp for equities, crypto and prediction markets in one place.
