What is Analytical MCP Server?
A Model Context Protocol server exposing 12 analytical tools for Claude, including descriptive statistics, regression (linear/polynomial/logistic/multivariate), hypothesis testing, data preprocessing, data visualization, multi-criteria decision analysis, ML model evaluation, logical argument/fallacy analysis, and Exa-backed research verification. It runs over stdio; the analytical core needs no API key, but research features require an EXA_API_KEY.
How to use Analytical MCP Server?
Install Node.js >=20.0.0, clone the repository, run npm install and npm run build, then configure Claude Desktop to launch the server with the EXA_API_KEY environment variable. Alternatively, use Docker with the docker run command and an .env file. Add the server to Claude Desktop’s mcpServers configuration with the appropriate command and args.
