A Stdio MCP server which proxies an SSE MCP server.
This proxy acts as a bridge between:
- An SSE-based MCP server endpoint
- Standard input/output for MCP client communication
It enables tools that use standard I/O for communication such as Claude Desktop (as of 2025-04-01) to interact with MCP implementations through an SSE interface.
- JDK 21 or higher
- Gradle 8.0+ (Wrapper included)
