What is Wm Mcp

The FRED Macroeconomic Data MCP Server is a specialized server that grants access to the Federal Reserve Economic Data (FRED) for analysis and insights into macroeconomic indicators such as GDP, employment, and inflation. It utilizes the Model Context Protocol (MCP) to seamlessly integrate with language models like Claude.

Use cases

This MCP server can be used for a variety of applications such as economic analysis, research in macroeconomics, educational purposes for students studying economics, and practical tasks by business analysts needing real-time economic indicators to inform decisions.

How to use

To use the server, set up a local development environment by cloning the repository, creating a virtual environment, and installing required dependencies. Configure the server by setting your FRED API key in the environment variables. Once set up, you can interact with the server in Claude Desktop to fetch and visualize economic data.

Key features

Key features of the FRED Macroeconomic Data MCP Server include access to a wide range of economic indicators, a search function for easily locating specific data series, real-time interaction with the FRED API for up-to-date information, and compatibility with Claude and other LLMs for integrated data utilization.

Where to use

The server is ideally used in environments where users need access to economic data, including academic institutions, research organizations, and business settings where timely economic insights can support strategic planning and decision-making.

FRED Macroeconomic Data MCP Server

A Model Context Protocol (MCP) server that provides access to Federal Reserve Economic Data (FRED) through Claude and other LLM clients. This server exposes FRED economic data series, search capabilities, and data retrieval tools.

Features

• Access to common FRED economic indicators (GDP, Employment, Inflation, etc.)
• Search functionality for FRED data series
• Real-time data fetching from FRED API
• Standardized data format for LLM consumption
• Built using the MCP Python SDK for seamless integration

Prerequisites

• Python 3.11 or higher
• uv - Modern Python package installer
• Claude Desktop for local usage
• FRED API Key (get one from FRED API)

Installation

1. Clone the repository:

git clone https://github.com/yourusername/WM_mcp.git
cd WM_mcp

2. Create and activate a virtual environment using uv:

uv venv
source .venv/bin/activate  # On Windows, use `.venv\Scripts\activate`

3. Install dependencies using uv:

uv pip install "mcp[cli]>=1.6.0" "colorama>=0.4.6" "numpy>=2.2.4" "pandas>=2.2.3" "python-dotenv>=1.1.0" "requests>=2.32.3"

4. Set up environment variables:

cp .env.example .env

Edit .env and add your FRED API key:

FRED_API_KEY=your_fred_api_key_here

Installing in Claude Desktop

1. Make sure Claude Desktop is installed and running
2. Open Claude Desktop settings:
   • Go to Settings > Developer > Edit Config
   • Add the following configuration to your claude_desktop_config.json:

{
  "mcpServers": {
    "FRED Macroeconomic Data Server": {
      "command": "/path/to/your/.local/bin/uv",
      "args": [
        "--directory",
        "/path/to/your/WM_mcp",
        "run",
        "fred_macroeco_server.py"
      ]
    }
  }
}

Replace /path/to/your/ with your actual paths. You can find uv’s path by running which uv in terminal.

Usage in Claude

1. First, search online for “using MCP resource in Claude Desktop Client” to understand how to include MCP resources in your conversations.

2. Once you’ve added the resource, you can interact with FRED data. Example prompt:

Use FRED APIs to get GDPs of USA last 20 years, draw chart

Available Resources

• file://series/available - List all available FRED series and their details

Available Tools

• fetch_series_data - Fetch data for any FRED series
• search_series - Search for FRED series by description

Development

For development and testing:

1. Run the MCP Inspector to test the server:

mcp dev fred_macroeco_server.py

This allows you to inspect resources, test tools, and verify server functionality.

2. For direct server execution (to check for issues):

python fred_macroeco_server.py

Note: The server uses stdio transport for communication with Claude Desktop. Use the MCP Inspector during development to catch and fix any issues before deploying to Claude Desktop.

Troubleshooting

1. If you get API key errors:

   • Verify your FRED API key is correctly set in .env
   • Check that the .env file is in the correct directory

2. If the server doesn’t appear in Claude Desktop:

   • Double-check your claude_desktop_config.json paths
   • Ensure uv and all dependencies are installed correctly
   • Try restarting Claude Desktop
