About

io.github.mrfentmen/colorblind-mcp is an MCP server published by mrfentmen. Marketplaces we read that list it: 1 (Official MCP Registry). The last change we recorded was on 2026-11-08. As of our marketplace pass on 2026-11-10.

What it asks for

  • Runs on your machine

None of the marketplaces we read publishes its tools or the settings it asks for.

What it declares, asks for and runs, in full

Only install plugins from developers you trust. We list what marketplaces publish and do not test plugins.

Package

npm @mrfentmen/colorblind-mcp (@mrfentmen/colorblind-mcp on npm)

  • npm downloads/month: 680 (2026-11-10)
  • Latest version on npm: 1.0.1, published 2026-10-28

Found by meaning, not by shared code or a shared repository: similar plugins stay separate products, and this is not a review or a recommendation.

Want this mark on your plugin in our catalog?

Prove you maintain it with a file in its repository, a file on your domain or a DNS record, and you can show this mark on the card, with live banners for your site and README. How verification works

You also get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and its remote endpoint goes on monitoring as a web service.

Data comes from the Official MCP Registry (registry.modelcontextprotocol.io), CC0 1.0. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
