Google Meridian MCP Server (google-meridian-mcp)

A Cloud-Agnostic, First-Principles Model Context Protocol (MCP) server for Google Meridian and Marketing Mix Modeling (MMM).

It empowers data scientists and AI assistants (Cursor, Claude Desktop, Antigravity) to create, audit, calibrate, and optimize mathematically sound, causally valid Marketing Mix Models with zero cloud vendor lock-in.

💡 Why First Principles Over Rigid Scripts?

Most assistant implementations rely on hardcoded procedural scripts (SKILL.md). In real-world data science, rigid scripts break because every business, industry, and marketing dataset is unique:

• A retail brand with 50 DMAs operates differently than a B2B SaaS startup with national data.

• App install targets (NON_REVENUE) require different priors than revenue models (REVENUE).

• Specific channel CPMs, flighting patterns, and Lift Tests vary across campaigns.

First Principles never change. Causal identification (DAGs), carryover/saturation physics (Adstock & Hill curves), Bayesian probability calibration, NUTS MCMC geometry ($\hat{R} < 1.05$), and KKT convex budget optimization apply universally to every dataset on Earth.

By anchoring this MCP server in First Principles & Dynamic Data Science Tools, the co-pilot adapts seamlessly to any specific edge case while guaranteeing mathematical rigor.
