概要

What is Mcp Data Visualization Server?

A Model Context Protocol server that transforms natural language into interactive data visualizations using DuckDB for data storage, Plotly for chart generation, and Ollama for local LLM processing. It integrates with Claude Desktop to let users manage databases, analyze data, and create charts through conversational commands.

How to use Mcp Data Visualization Server?

Install Python 3.8+, Ollama, and Claude Desktop. Clone the repository, create a virtual environment, install dependencies (mcp, duckdb, pandas, plotly, ollama, etc.), start Ollama, pull a model (e.g., qwen2:0.5b), and add the server configuration to Claude Desktop’s claude_desktop_config.json. Restart Claude Desktop and chat using natural language requests.

Key features of Mcp Data Visualization Server

  • Natural language interface for database management and chart creation
  • Interactive charts (bar, line, scatter, pie, histogram, box, heatmap, area)
  • Flexible database switching with an interactive browser
  • Local LLM processing via Ollama for privacy
  • Automatic statistical insights and pattern detection
  • SQL injection protection and input validation

Use cases of Mcp Data Visualization Server

  • Business analytics: sales dashboards, customer segmentation, regional performance
  • Data science: exploratory analysis, correlation heatmaps, outlier detection
  • Quick ad‑hoc queries and visualizations without writing SQL or code
  • Privacy‑focused analysis where all data stays on the local machine

よくある質問

1

What are the prerequisites for running the server?

Python 3.8+, Ollama installed and running, and Claude Desktop installed. A lightweight Ollama model such as `qwen2:0.5b` is recommended.

2

How is data stored and processed?

Data is stored in local DuckDB database files (`.duckdb`). All processing happens on your machine; no data is sent to external services.

3

Does the server require an internet connection?

No. The LLM runs locally via Ollama, and all database operations are local. An internet connection is only needed for initial installation of dependencies or pulling an Ollama model.

4

What chart types are available?

Bar, line, scatter, pie, histogram, box, heatmap, and area charts. Chart type suggestions and guided configuration are available through natural language.

5

How can I switch to a different database?

Use natural language commands like “Switch to in-memory database” or “Connect to C:/path/to/database.duckdb”, or use the `browse_databases` and `change_database` tools.
