The chartforge MCP server connects an MCP client to ChartForge for generating charts and diagrams from natural-language descriptions. It runs through npx with a ChartForge API key, and supports chart refinement, style discovery, and configurable dimensions. Reach for it when an agent needs to create or iteratively adjust visualizations from conversational instructions.

Use cases

Generate revenue charts from natural-language descriptions
Create architecture diagrams for software systems
Map marketing flows with Sankey diagrams
Refine an existing chart using its chart ID
Inspect available visual style presets

Key features

Natural-language chart generation
Chart refinement by chart ID
Seven named style presets
Configurable pixel dimensions
Style preset discovery

How Chartforge works

What chartforge MCP server does

The chartforge MCP server exposes ChartForge’s visualization capabilities through MCP. An agent can describe a chart or diagram in natural language, receive a generated result, and then request changes to that result using its chart ID. The server is suited to workflows where visualization requirements are expressed conversationally rather than assembled through a charting library by hand.

Supported examples include a bar chart for quarterly revenue, a microservices architecture diagram, and a Sankey diagram showing movement from marketing budget to conversions. The supplied tools do not limit requests to one diagram type, so the prompt determines the requested visualization.

How it works

The server is started with the chartforge-mcp package through npx. MCP-compatible client software launches the process and supplies the CHARTFORGE_API_KEY environment variable. Chart generation uses the generate_chart tool, which accepts a required natural-language prompt and optional presentation settings.

A generated chart can be changed later with refine_chart. That operation requires the chartId returned from an earlier generation and a description of the desired modification. Before generating a result, an agent can call list_styles to inspect the available style presets and their descriptions.

Setup and configuration

The chartforge MCP server requires an API key issued through chartforgeai.com. For Claude Desktop, add a chartforge entry to claude_desktop_config.json, use npx as the command, pass chartforge-mcp as its argument, and place the key in the server’s env object.

CHARTFORGE_API_URL is optional. If set, it provides a custom API endpoint; otherwise, the server uses https://chartforgeai.com. The documented setup does not require additional configuration values.

Tools and capabilities

generate_chart creates a chart or diagram from a required prompt.
generate_chart accepts an optional style preset: midnight, frost, ember, minimal, corporate, neon, or light.
generate_chart accepts optional width and height values in pixels. The documented defaults are 1200 by 800.
refine_chart modifies an existing result with a required chart ID and change description.
list_styles returns the available style presets with descriptions.

Limitations and notes

The chartforge MCP server depends on a valid ChartForge API key and the ChartForge service endpoint. Refinement requires retaining the chart ID from a previous generation. The provided material documents Claude Desktop setup, but does not describe authentication alternatives, local rendering, data-file inputs, or support for other MCP clients. Style names and image dimensions are optional generation parameters; the source does not specify additional output formats or chart-specific parameters.

Frequently Asked Questions about Chartforge

chartforge is an MCP server that connects an MCP client to the ChartForge service and provides tools for generating charts from natural-language prompts, refining existing charts by ID, and listing style presets. It supports configurable dimensions and named visual styles for chart and diagram requests.

Install it by configuring Claude Desktop to run `npx` with `chartforge-mcp` as the argument. Add the server entry to `claude_desktop_config.json` and provide `CHARTFORGE_API_KEY` in its environment settings.

Yes, chartforge has documented Claude Desktop setup instructions. Configure the `chartforge` MCP server entry, launch `chartforge-mcp` with `npx`, and supply the required ChartForge API key.

Use the `refine_chart` tool with the chart ID from the earlier generation and a description of the change. The tool is intended to modify a previously generated chart.
