@ToolParam need a name Attribute !!!

[jinkunaier]

Why doesn't the @ToolParam have a name attribute? If the actual names of method parameters are lost after compilation, it will result in MCP being unable to correctly assign values to the parameters during invocation.

what about using @JsonProperty?

According to Tool Calling documentation:

Besides the @ToolParam annotation, you can also use the @Schema annotation from Swagger or @JsonProperty from Jackson.

Since @ToolParam was newly introduced with M6 as a Spring AI provided annotation (as an alternative for @JsonProperty?), IMHO one could argue it should provide the same ability to set the parameter name (assuming it gets transmitted and is used by the LLM). Maybe support can be added in a future release?
