Our reading of affectUI, from the data

affectUI is a e-commerce MCP server from flohoeller, listed in the official MCP Registry.

Its 4 tools add about 610 tokens to every model turn, lighter than the e-commerce median of 1,843 tokens across 70 measured servers (measured 2026-10-19).

Maintenance is active: the last public signal was in the last day (2026-10-18). For comparison, 70% of e-commerce servers are active or maintained.

With 69 GitHub stars it ranks #31 of 936 e-commerce servers we index.

It runs as a hosted endpoint, so there is nothing to install.
