Legal Marketing Data MCP Server

Legal-marketing open data

Published by Probative Growth, a marketing agency for US law firms (SEO and ads, at published monthly prices). Prices: probativegrowth.com/pricing · About: probativegrowth.com/about

Open, citable datasets on US law-firm marketing, maintained by Probative Growth: lawyer advertising rules for all 50 states and DC, bar ad filing and fees, ethics opinions, ad-platform policies, attorney fee caps, federal MDL dockets, Spanish-language demand, and official court, complaint, crash, price and wage statistics.

Every record quotes its primary source and the date it was checked. Each dataset has a DOI on Zenodo. Not legal advice: check the source and your own counsel before you rely on a rule.

Each folder holds the full CSV and JSON, a README.txt with the fields, changes.json (the change log), openapi.json, CITATION.cff and starter.ipynb (a notebook that loads the data and works through example questions; on Kaggle, import it from its GitHub link). Found a wrong value? Report it here. The root has a CITATION.cff (GitHub's "Cite this repository" button) and a Frictionless datapackage.json that describes every CSV and its fields. Each dataset version has a tagged release.
