echo
plain tool.
get_weather
a valid x-mcp-header: "City" annotation on its city argument.
invalid_header_tool
an annotation using the header name "Bad Header". The space makes it an invalid RFC 9110 token, so the whole tool definition is invalid.
trigger_invalid_params
answered with a real -32602 Invalid params error whose message is not about a missing tool.
