Plots MCP Server

A Model Context Protocol (MCP) server for data visualization. It exposes tools to render charts (line, bar, pie, scatter, heatmap, etc.) from data and returns the plot as image/base64 text/mermaid diagram. It runs locally over stdio via the published package.

People connecting this server to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Plots

before you install - you'll need

LOG_LEVEL, CHART_DEFAULT_WIDTH, CHART_DEFAULT_HEIGHT, MCP_TRANSPORT, MCP_HOST, MCP_PORT, CHART_DEFAULT_DPI, CHART_MAX_DATA_POINTS are optional or environment-specific per the README.

Claude Code

claude mcp add mr901-mcp-plots -- uvx mcp-plots

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "mr901-mcp-plots": {
      "command": "uvx",
      "args": [
        "mcp-plots"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

pypi package mcp-plots - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.MR901 is GitHub-verified and matches the repo owner

05 · Plots FAQ

What is Plots?

Is Plots still maintained?

Yes - as of 2026-08-25, its last commit was 2025-12-02. We re-verify nightly.

How do I install Plots?

Run `uvx mcp-plots`. The README documents 8 environment variables (LOG_LEVEL, CHART_DEFAULT_WIDTH, CHART_DEFAULT_HEIGHT…) to set first. LOG_LEVEL, CHART_DEFAULT_WIDTH, CHART_DEFAULT_HEIGHT, MCP_TRANSPORT, MCP_HOST, MCP_PORT, CHART_DEFAULT_DPI, CHART_MAX_DATA_POINTS are optional or environment-specific per the README. You can also paste the ready-made client config above.

Does Plots run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
