+# LangGraph Agent with Claude and Tool MCP Servers
+
+This project demonstrates how to create an agent using LangGraph with Claude 3.5 Sonnet which connects to a Remote MCP Server.
+
+## Overview
+
+The agent uses:
+- Claude 3.5 Sonnet as the language model
+- LangGraph for orchestration
+- Connects to a Remote MCP server
+
+## Architecture
+
+```mermaid
+---
+config:
+  flowchart:
+    curve: linear
+---
+graph TD;
+	__start__([<p>__start__</p>]):::first
+	agent(agent)
+	tools(tools)
+	__end__([<p>__end__</p>]):::last
+	__start__ --> agent;
+	tools --> agent;
+	agent -.-> tools;
+	agent -.-> __end__;
+	classDef default fill:#f2f0ff,line-height:1.2
+	classDef first fill-opacity:0
+	classDef last fill:#bfb6fc
+```
+
+The workflow follows a ReAct pattern:
+1. Query is sent to the agent (Claude)
+2. Agent decides whether to use tools or provide a final answer
+3. If tools are needed, the request is sent to the remote MCP server
+4. Results from tools are sent back to the agent
+5. Process repeats until the agent has enough information to provide a final answer
+
+## Prerequisites
+
+- Python 3.10+
+- `langchain-anthropic`
+- `langchain-mcp-adapters`
+- `langgraph`
+- Anthropic API key set as an environment variable
+
+## Installation
+
+```bash
+uv venv -p 3.11 .venv
+.venv\Scripts\activate
+uv sync
+```
+
+Set your API keys and MCP Remote Server URL as environment variables in .env
+
+```bash
+ANTHROPIC_API_KEY=your_anthropic_api_key
+UIPATH_MCP_SERVER_URL=https://alpha.uipath.com/account/tenant/mcp_/mcp/server_slug/sse
+```
+
+## Debugging
+
+For debugging issues:
+
+1. Check logs for any connection or runtime errors:
+   ```bash
+   uipath run agent --debug '{"messages": [{"type": "human", "content": "What is 2+2"}]}'
+   ```
+
