What is Chart MCP Server?
Chart MCP Server is a microservice built on FastAPI that allows users to generate chart images by submitting Python code (especially matplotlib code). The server will execute the code and return the URL of the generated chart image.How to use Chart MCP Server?
You can send JSON data containing Python plotting code to the server via an HTTP POST request. The server will execute the code and return the URL of the generated chart image.Applicable scenarios
Suitable for applications that need to dynamically generate charts, automated reporting systems, educational demonstration tools, etc. Particularly suitable for applications that do not want to directly handle Python code on the front - end but need chart generation capabilities.Main features
Python code execution
Supports executing Python scripts containing matplotlib plotting code
Chart image generation
Automatically saves the chart generated by Python code as a PNG image
RESTful API
Provides a simple HTTP API interface, easy to integrate into various applications
Advantages
Generate charts without installing a Python environment on the front - end
Support full matplotlib functionality
Easy to deploy, built on FastAPI
Limitations
Requires an internet connection to call the API
Executing untrusted code may pose security risks
Performance depends on server configuration
How to use
Install dependencies
Ensure that Python 3.11+ and the required dependency packages are installed on the system
