About MCP Agent

MCP Agent is optimized using the ReWOO pattern, enabling even LLMs with fewer parameters to efficiently utilize MCP Server with minimal token consumption.

Overview

What is MCP Agent?

MCP Agent is a LangGraph agent based on the ReWOO (Reasoning WithOut Observation) pattern that reduces prompt complexity for small LLMs and integrates with the Model Context Protocol (MCP) server for efficient tool execution.

How to use MCP Agent?

Install dependencies, set environment variables as shown in .env.example, configure MCP servers in mcp.json, then run python main.py. The agent executes the ReWOO workflow through a series of LangGraph nodes.

Key features of MCP Agent

Implements the ReWOO pattern to minimize prompt complexity, especially for small LLMs.
Filters available tools to those most relevant for the current query.
Validates and automatically corrects execution plans on errors.
Manages evidence in a dictionary, referencing previous results with placeholders.
Orchestrates nine specialized LangGraph nodes for a structured workflow.
Designed for efficient interaction with any MCP-compatible server.

Use cases of MCP Agent

Automate multi-step reasoning tasks via MCP server tools.
Perform complex tool calls using small or resource-constrained language models.
Reduce token usage and prompt overloading compared to the ReAct pattern.
Validate tool plans before execution to catch errors early.
