Color-vision accessibility. Check whether a palette or an image is colorblind-safe and name the conflicting pairs, generate colorblind-safe palettes (Okabe-Ito seeded), recolor an image as protanopia/deuteranopia/tritanopia renders it, and generate Ishihara-style test plates. Built on Machado, Oliveira & Fernandes (2009) + CIEDE2000, published open access at doi.org/10.5281/zenodo.21310578. Runs locally over stdio, no network calls. Install: npx -y cvdsafe-mcp and npx -y colorblind-mcp.
