RegiaBI charts MCP server

RegiaBI charts: an MCP server and agent plugin

Chart code that fits your data first try, as source you own: you pay to author it, never to run it.

This repository packages the RegiaBI chart MCP server (com.regiabi/chart-mcp, published on npm as @bicharts/chart-mcp) and its agent skill as a one-command plugin for Claude Code, GitHub Copilot CLI, Codex and Gemini CLI. It holds the plugin manifests, the pinned server command and the skill. The server itself is the npm package.

What it does

Give your coding agent a table (a CSV, a dataframe, or a query result from a semantic model) and it gets back working, interactive chart code that fits that data:

leaves your machine for this step.

• It profiles your data locally. Row counts, cardinalities, measures versus dimensions, dates, places. No data

rather than a guess, so a map is only offered when there are places to map and a sankey only when there are flows.

• It ranks about 90 chart types by what the data can honestly show, using a server-side eligibility engine

Python. The code has already passed render checks. It needs no license, no account and no connection to us to run, deploy or ship, for any number of viewers.

• It returns verified source you own: D3 for JavaScript and TypeScript projects, Plotly or matplotlib for

The tools:

Install

Claude Code

/plugin marketplace add codexguy/regiabi-plugins
/plugin install regiabi-charts@regiabi

GitHub Copilot CLI

copilot plugin marketplace add codexguy/regiabi-plugins
copilot plugin install regiabi-charts@regiabi

Codex

codex plugin marketplace add codexguy/regiabi-plugins

Then install RegiaBI charts from the Plugins Directory.

Gemini CLI

gemini extensions install https://github.com/codexguy/regiabi-plugins

Any other MCP client

VS Code, Cursor, Claude Desktop and any other MCP client can run the server directly:

{
  "mcpServers": {
    "bic-chart": {
      "command": "npx",
      "args": ["-y", "@bicharts/chart-mcp"]
    }
  }
}

Configure

Nothing, usually. Writing a chart needs a RegiaBI account; running a chart you've already generated needs nothing.

Sign in when it asks. The first time your agent calls a tool that needs an account, the server opens your browser at bizintelligencechampions.com. Sign in, or create a free account (it comes with a free trial), and click Allow. The call your agent made then finishes by itself. The server keeps the sign-in in ~/.bic/oauth.json and renews it on its own, and you can sign a device out at any time from your account page.

Or use a license key (a machine with no browser, CI, a container). Leave sign-in alone and give the server your account's credentials instead, in one of two ways:

store), or as environment variables on the server: BICLICENSEE and BICLICENSEKEY, plus BICSECRET_KEY if your account uses one.

• When the plugin asks (Claude Code prompts on install and keeps the key in your system's secure credential

~/.bic/credentials.json (or point BICCREDENTIALSFILE at another path):

• A credentials file, so no secret ever sits in a project's committed config. Put this in

{ "licensee": "...", "licenseKey": "..." }
