Installation

1. Clone this repository

2. Install dependencies:

pip install -r requirements.txt

Usage

Running the Server

Start the server with:

python src/server.py

The server will start on http://127.0.0.1:8001 with the following endpoints:

• Tools:

  • current_datetime(timezone: str): Get current date and time in a specific timezone

• Resources:

  • users://{user_id}/profile: Get a user's profile by ID

  • greeting://{name}: Get a personalized greeting

Running the Client

Run the example client with:

python src/client.py

The client will:

1. List all available tools

2. List all available resources

3. Call the current_datetime tool with "America/New_York" timezone

Running the LangChain Client Example

This project includes an example of using the MCP server with LangChain, based on the langchain-mcp-adapters repository.

To run the LangChain client example:

1. First, make sure the MCP server is running:

python src/server.py

2. Set your OpenAI API key as an environment variable:

# On Windows
set OPENAI_API_KEY=your-api-key-here

# On Unix/Linux/MacOS
export OPENAI_API_KEY=your-api-key-here

3. Run the LangChain client:

python src/langchain_client.py

The LangChain client demonstrates how to integrate the MCP server with LangChain's agent system, allowing for more complex interactions and reasoning about the available tools.

Cursor Configuration

To use this server with Cursor IDE, you need to configure it in your Cursor settings. Create or update the mcp.json file in your Cursor configuration directory with the following:

{
  "mcpServers": {
    "my-mcp-local-server": {
      "command": "path/to/your/python.exe",
      "args": [
        "path/to/your/server.py"
      ],
      "description": "MCP local server"
    },
    "my-mcp-remote-server": {
      "url": "http://127.0.0.1:8001/mcp",
      "description": "MCP remote server"
    }
  }
}

This configuration provides two ways to connect to the server:

1. my-mcp-local-server: Runs the server locally through Python

2. my-mcp-remote-server: Connects to the server running on port 8001

Make sure to replace the paths with your actual Python and server script paths.

Example API Usage

Get Current Time

result = await client.call_tool("current_datetime", {"timezone": "America/New_York"})

Get User Profile

profile = await client.read_resource("users://123/profile")

Get Greeting

greeting = await client.read_resource("greeting://John")

Development

The server is built using FastMCP, which provides a simple way to create MCP-compatible servers. The main components are:

• server.py: Contains the server implementation with tools and resources

• client.py: Example client that demonstrates how to interact with the server
