Install Blueprint Chart in Claude Code, Cursor or VS Code

Runs npx -y @blueprint-chart/mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Blueprint Chart repository's README, as published. We do not edit it. Read it on GitHub

Model Context Protocol server for authoring Blueprint Chart .bpc files with LLMs, grounded in real dataviz pedagogy with a tight parse + render feedback loop. An open, plain-text chart format an AI can write and any browser can render. Self-contained, no backend, no account required.

The MCP exposes Blueprint Chart's dataviz handbook, DSL grammar reference, chart-type docs, and canonical samples as MCP resources, plus eleven deterministic tools: validatedsl, inspectdsl, recommendcharttype, render, listcharttypes, describecharttype, getexample, getgrammar, exportchart, searchexamples, and list_palettes. Your LLM writes the .bpc; the MCP grounds it in real dataviz pedagogy and gives it a tight feedback loop.
