Best For

Contract is available with explicit auth and schema references.

Not Ideal For

mcptools-langchain-integration is not ideal for teams that need stronger public trust telemetry, lower setup complexity, or more explicit contract coverage before production rollout.

Setup snapshot

git clone https://github.com/shashwat001/mcptools-langchain-integration.git

1
Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Langchain TypeScript with MCP Tools Integration

A TypeScript project that integrates Langchain with Model Context Protocol (MCP) tools, allowing interaction with Language Models and execution of various tools through a chat interface.

Prerequisites

Node.js (v14 or higher)
npm
Ollama server running locally
MCP server running locally

Installation

Clone the repository:

git clone https://github.com/shashwat001/mcptools-langchain-integration.git
cd mcptools-langchain-integration

Install dependencies:

npm install

Configuration

Ollama Configuration

The project uses Ollama for LLM integration. Configure Ollama settings in src/llm.js:

export const ollamaConfig = {
    baseUrl: "http://localhost:11434",
    model: "llama3.1:8b-instruct-q6_K",
    temperature: 0.1,
    maxRetries: 2
};

MCP Server Configuration

MCP server settings can be configured in src/llm.js:

export const mcpConfig = {
    serverUrl: 'http://localhost:7000/sse',
    clientInfo: {
        name: 'ollama-client',
        version: '1.0.0'
    }
};

System Prompt

The system prompt for tool interactions can be modified in src/llm.js:

export const systemPromptForTools = "In this environment you have access to a set of tools you can use to answer the user's question.\n Don't ask user to execute the functions and decide yourself whether to call the tool or not.\nNever call more than one tool at a time.";

Running the Application

Start the Ollama server (make sure it's running on http://localhost:11434)
Start the MCP server (make sure it's running on http://localhost:7000)
Run the application:

node src/index.js

Features

Interactive chat interface with LLM
Integration with MCP tools
Tool execution through chat
Support for SSE (Server-Sent Events) based MCP server

Important Notes

MCP Server Caution

The project currently uses an SSE-based MCP server. Exercise caution as the MCP server has write permissions that could make unintended system changes. Always review tool permissions before execution.
