## Verdict

Socraticstatic Chart Color System MCP server answered 100% of Glimind's liveness checks over 30 days, better than 42% of MCP servers, with 740 ms median handshake and 1 outage in 90 days. Its agent-readiness grade is A (90/100) across 4 tools, costing an agent about 1,044 tokens to load. Checked every few minutes; no tool is ever called.

## Tools (4)

- `audit_palette`: Audit existing chart colors for accessibility: pairwise OKLab separation under normal vision, deuteranopia, protanopia, tritanopia and achromatopsia, plus WCAG 
- `build_ramp`: Build an evenly spaced perceptual (OKLab) color scale: sequential from start to end, or diverging from start through mid to end. Returns the steps and a backgro
- `simulate_palette`: Show what each color looks like to readers with deuteranopia, protanopia, tritanopia or achromatopsia (published Machado 2009 matrices), so an assistant can des
- `solve_palette`: Generate a categorical chart palette of n colors (1-12) that maximizes perceptual separation under normal vision and colorblindness, with the given brand colors
