viz_mcp

Render charts, diagrams, metrics, and SVGs directly in chat. Supported agents can produce data visualizations without any external services — they render inline as the session runs.

Tools

Tool	What it renders
`render_chart`	Line, bar, pie, scatter, and other chart types from structured data
`render_diagram`	Flowcharts, sequence diagrams, entity-relationship diagrams (Mermaid syntax)
`render_metric`	Single-value metrics with label and optional trend indicator
`render_progress`	Progress bars and completion indicators
`render_svg`	Raw SVG markup rendered as an image

All outputs render inline in the chat panel. No file exports, no external URLs — the rendered content is embedded directly in the session.
