I have the same problem; can you handle the string type access on the mcp side and try to fix;

pullNumber, err := RequiredInt(request, "pullNumber")
if err != nil {
pullNumberStr, err := requiredParamstring
if err != nil {
return mcp.NewToolResultError(err.Error()), nil
}
pullNumber, err = strconv.Atoi(pullNumberStr)
if err != nil {
return mcp.NewToolResultError(err.Error()), nil
}
}
