How to Set Up and Use Market Sizing
The Market Sizing MCP Server is a TypeScript-based MCP server that provides 28 specialized tools and 15 professional business analysis prompts by integrating with eight major economic data sources: Alpha Vantage, Bureau of Labor Statistics (BLS), Census Bureau, FRED (Federal Reserve), IMF, Nasdaq Data Link, OECD, and World Bank. It enables AI assistants to calculate Total Addressable Market (TAM) and Serviceable Addressable Market (SAM) figures, retrieve real-time financial and economic indicators, run industry analysis, and generate funding-pitch-ready market research — all backed by authoritative public data rather than training-data estimates. Business analysts, startup founders, and investors use it to produce credible, source-cited market sizing figures directly from Claude or another MCP client.
Prerequisites
- Node.js 20.x or later installed
- npm or yarn package manager
- Optional but recommended: API keys for Alpha Vantage (https://www.alphavantage.co/) and FRED (https://fred.stlouisfed.org/docs/api/api_key.html) — the server works with smart defaults without them
- An MCP-compatible client such as Claude Desktop or Claude Code
- Git to clone the repository
Clone the repository
Clone the TAM-MCP-Server repository from GitHub to your local machine.
git clone https://github.com/gvaibhav/TAM-MCP-Server.git
cd TAM-MCP-ServerInstall dependencies
Install all Node.js dependencies using npm.
npm installConfigure environment variables
Copy the example environment file and add your API keys for the data sources you want to use. The server uses smart defaults so it works without keys, but API keys unlock full data access.
cp .env.example .envBuild the server
Compile the TypeScript source to JavaScript.
npm run buildStart the server
Start the server in HTTP mode (recommended) for MCP clients that support HTTP transport, or in stdio mode for direct process integration.
npm run start:httpAdd to your MCP client configuration
Register the server in your claude_desktop_config.json. The server supports both stdio and HTTP transports — use the HTTP approach for Claude Desktop.

Client configuration
Add this to your claude_desktop_config.json. Adjust the cwd path to where you cloned the repository. Uses STDIO transport for direct integration.

These prompts exercise the TAM/SAM calculation tools, data source integrations, and the pre-built business analysis prompt templates.
- "Calculate the TAM for the B2B SaaS market in North America"
- "Get the current US GDP growth rate from FRED"
- "Show me a company overview for MSFT using Alpha Vantage"
- "Prepare a market sizing section for a startup pitch in the healthcare AI space"
- "Compare unemployment data from BLS across the last 5 years and chart the trend"Troubleshooting Market Sizing
Data source tools return 'API key missing' or limited results
Add the relevant API key to your .env file. ALPHA_VANTAGE_API_KEY is needed for stock/company data, FRED_API_KEY for Federal Reserve economic indicators. Free keys are available from each provider's website.
Server fails to start with TypeScript or module errors
Ensure you ran 'npm run build' before starting. If errors persist, delete node_modules and the dist folder, then re-run 'npm install && npm run build'.
Claude Desktop cannot connect to the HTTP server
For Claude Desktop, use the stdio transport config with 'npm run start:stdio' instead of HTTP. HTTP transport works best with MCP Inspector or frameworks that support SSE/HTTP connections.
