"LangGraph" matching MCP servers:

A clean, modular Model Context Protocol server implementation for LangGraph documentation, designed for easy extensibility with tools and resources.

Exposes a RAG agent built with LangGraph, enabling retrieval-augmented question answering over a PostgreSQL/pgvector corpus via the MCP protocol.

An MCP server that utilizes LangGraph and Google Gemini to conduct comprehensive research through multi-iteration deep searches and quick results. It provides high-quality analysis with automated citations and grounding metadata for thorough investigations.

Turns a shopping list FastAPI app into an MCP server, enabling a LangGraph chatbot to manage shopping lists via natural language.

Enables LLM-powered agents to securely communicate with and orchestrate downstream microservices via FastAPI endpoints exposed as MCP tools.

MCP server for AWS DynamoDB CRM data, enabling LangGraph agents to discover and call tools to retrieve customer accounts and support tickets via the Model Context Protocol.

Provides web search, dice rolling, text processing, and dad jokes tools, integrated with LangGraph for intelligent workflow orchestration.

Template for serving FastMCP servers over Streamable HTTP within a LangGraph Server, including an example math_add tool.

Demonstrates an MCP server with calculate and text_stats tools over Streamable HTTP, integrating with LangChain/LangGraph and n8n agents.

A LangGraph-powered MCP server for infrastructure orchestration with autonomous subagents.

Enables Claude to search and retrieve documents from Azure AI Search indexes with intelligent summarization and analysis using LangGraph workflows and optional Google Gemini integration.

An MCP-compatible RAG backend using LangGraph and FastAPI, enabling chaining of AI model logic with document context search.

Provides an MCP interface to the ERA RINF railway infrastructure database for Poland and Czech Republic, enabling route planning, train compatibility checks (gauge, axle load, length, clearance), weather risk assessment, and traction planning, with a LangGraph agent integrating a custom MCP server and an OpenWeather MCP server.

Enables safe, read-only analysis of e-commerce data, including semantic product search, sales summaries, top products, customer orders, and low-stock alerts, through MCP tools and a LangGraph agent.

Enables AI assistants such as Claude to list and upload images on an image annotation platform, add, replace, or remove pins, polygons, circles, rectangles, and arrows, edit image metadata, and export annotations as COCO JSON or YOLO training data. It can run over stdio or Streamable HTTP so multiple clients can share one server, with an included LangGraph terminal agent.

Enables web search capabilities through the Tavily API and serves as a demonstration platform for building custom MCP tools. Designed for educational purposes to showcase MCP server development and LangGraph integration.

MCP server that provides F1 telemetry analysis, tyre degradation modeling, and pit strategy recommendations, delivering race engineer-style calls grounded in real data. It exposes tools for degradation fits, fuel correction, and strategy reasoning via LangGraph.

A Model Context Protocol server that enables connecting LangChain or LangGraph agents to a MyShows.me profile, allowing users to manage and search for TV shows via API.

Domain-Driven MCP server for ed-tech workflows, exposing validated MCP tools backed by LangGraph agents, Supabase document retrieval, web search, and YouTube video discovery.

An MCP server that provides web search capabilities through the Tavily API and weather data retrieval tools. It demonstrates how to integrate external APIs into AI applications and build agentic workflows with LangGraph.
