Who it is for
B2B sales managers and commercial teams that already work inside GEMBA.
Overview
Gemba connects an authenticated GEMBA workspace to ChatGPT so that B2B commercial teams can put questions to their own sales data without opening the workspace interface itself.
The material it reaches covers sales and margin figures, customers, orders, and products, together with current-account debt and the objectives a team is measured against. That puts commercial performance, outstanding balances, and targets in a single view, and a question can cross between them in one exchange.
The record describes inspection of existing records rather than editing them, and everything returned stays scoped to the workspace the credentials belong to.

Outstanding customer debt is queryable next to sales and margin, which is less common in sales reporting connectors.
Availability
Gemba is listed in the ChatGPT apps directory only. Gemba Commerce has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from Gemba's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Gemba Commerce, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
