Universal MCP server of smart tools
Point your agent at one endpoint — no key required — and ask for a chart.
Each Graffiticode tool is a domain language wrapped by a specialized AI that knows the solution space — so your agent delegates to a specialist instead of guessing, and gets back a validated, interactive result.

Revenue as vertical bars (thousands): 120, 150, 170, 210, 240, 230, 290, 340. A smooth line on a secondary y-axis shows quarter-over-quarter growth percent: 0, 25, 13, 24, 14, -4, 26, 17. Label the left axis 'Revenue ($K)' and the right axis 'Growth (%)'. Include a legend, value labels on the bars, light gridlines, and a clean modern theme."
