The optional MinIO integration of mcp-echarts solves the problem of distribution performance of AI-generated charts. The traditional way of directly transmitting charts Base64 encoding will generate a large amount of data, but through the MinIO object storage solution, the tool only needs to return a short URL link to realize the sharing of charts. The specific implementation process includes: the generated chart image is automatically uploaded to the MinIO storage bucket, the system returns the corresponding access link, and the front-end can display the chart by simply loading this link.
The advantages of the program are threefold:
- Improved network transmission efficiency: URL links reduce data transmission by more than 90% compared to Base64 encoding
- Ease of sharing: Generate chart URLs that can be embedded directly into reports or shared with others.
- System stability: automatically downgrade to Base64 output when MinIO is unavailable to ensure service continuity
The configuration process is also extremely easy, simply set the MinIO connection parameters (endpoints, ports, authentication information, etc.) in the .env file and the tool will automatically handle all subsequent uploads and link generation.
