About matplotlibnet

matplotlibnet is an MCP server published by the GitHub account xkqg. Renders MatPlotLibNet charts to PNG, SVG or PDF from a JSON spec an AI agent writes.

It runs on your own machine: your AI client starts it from the NuGet package MatPlotLibNet.Mcp at version 1.18.1.

It asks for no keys or passwords.

Version 1.18.1 was published on 12 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 7 automated checks on registry metadata: 4 pass, 0 warn, 0 fail, 3 info. How we check.

What it asks for

Variable	Required	Secret	Description
`MATPLOTLIBNET_MCP_OUTPUT_ROOT`	No	No	The only directory save_chart may write under. Defaults to the system temp directory.
`MATPLOTLIBNET_FONTS`	No	No	Font files (.ttf, .otf) and directories of them, separated by ';', registered at startup so a chart can use a script the bundled font lacks (Devanagari, Thai, Chinese). Arabic and Hebrew work without it.
