Das Erstellen von MCP-Servern erfordert in der Regel viel Standardcode und Konfiguration. FastMCP vereinfacht die Einrichtung von MCP-Servern erheblich.
LangChain MCP-Adapter können problemlos eine Verbindung zu lokalen oder externen MCP-Servern herstellen.
Dieses Beispiel verwendet FastMCP, um einen lokalen MCP-Server zu erstellen und anschließend LangChain MCP-Adapter auf der Clientseite. Da dieses Beispiel ein OpenAI Large Language Model (LLM) verwendet, nutzt es auch die OpenAI-Implementierung von LangChain zur Kommunikation mit dem LLM. Es erstellt einen LangGraph ReAct (Reasoning and Acting)-Agenten. Asyncio wird für asynchrone Funktionen benötigt.
Da in diesem Beispiel ein lokaler MCP-Server verwendet wird, nutzt die Verbindung („Transport“) stdio (Python-Standard-Ein-/Ausgabeströme). Ein externer MCP-Server würde anstelle von stdio Server-Sent Events (SSE) oder WebSockets-Transport erfordern.
Dem LLM können alle möglichen Fragen zu einer Aktie gestellt werden. Anschließend ruft der LLM die im MCP-Server definierten Tools auf, sammelt alle Informationen und antwortet mit den gesammelten Informationen.
Wie Sie der Antwort entnehmen können, wurden alle 3 im MCP-Server definierten Tools verwendet:
