mcp-echarts is designed with a flexible communication protocol system to fit the integration needs of various AI application platforms. The tool provides three main protocol interfaces: the standard input/output (stdio) mode is suitable for desktop AI applications to call directly; the server-sent events (SSE) protocol is suitable for browser-based web applications; and the streamable interface optimizes large-scale data interaction scenarios.
In terms of concrete realization:
- The stdio mode is invoked by default via the npx command and is suitable for scenarios such as Claude desktop version, VSCode plug-ins, etc.
- SSE mode requires the tool to be deployed as an HTTP service (default port 3033) to provide real-time event push capability
- The streamable model is also based on HTTP services, but uses a streaming protocol that is better suited for large data transfers
This multi-protocol architecture ensures that the most suitable integration method can be found for both local AI applications and cloud-based service platforms. Developers can freely choose the protocol type and customize listening ports and access paths via command line parameters to fully meet the requirements of different deployment environments.
