G2
The software review marketplace, with buyer intent data on the companies researching your product and its competitors.
Updated Sep 27, 2026
Overview
G2 is a marketplace where buyers compare business software through user reviews. For vendors listed on it, G2 Buyer Intent shows which companies are researching their product, category or competitors, alongside G2's reviews, product catalog and categories.
The hosted MCP server signs in with OAuth 2.0. In Claude and ChatGPT, add the G2 MCP connector from their catalogs. G2's OAuth server doesn't support Dynamic Client Registration, so any other client first registers an OAuth app in the G2 Developer Portal and uses its client ID and secret. What an account can read depends on its G2 subscription: buyer intent needs a Buyer Intent license, and Market Intelligence reviews need an Enterprise package.
The REST API takes a G2 access token as a Bearer token. Create one in the G2 Developer Portal under Access Tokens and choose the endpoints it can reach; tokens expire a year after they are created. G2 allows 100 API requests per second from each IP address.
