Like you mentioned in the issue, I also feel a simple strings.EqualFold should do the job. All unit tests are passing successfully. I also changed Content-Length in the line below to different variations like content-length, COntent-LeNgth, etc., and in all cases the tests ran successfully. https://github.com/modelcontextprotocol/go-sdk/blob/main/internal/jsonrpc2/frame.go#L203 |
