MCP tool callback integration not working

[thingersoft]

Bug description
After setting spring.ai.mcp.client.toolcallback.enabled to true the MCP tool callback integration doesn't seem to be active.
The configured MCP server is detected at startup but simple requests made by the auto-configured ChatClient to OpenAI models contain no tool definitions.
Same MCP server with same configuration json is working fine in Claude Desktop client.

Environment
Spring AI 1.0.0-SNAPSHOT @ March 26, 2025, 7:00 PM PDT
Java 21

Sorry had wrong indications from gpt-4o 😅
I see from reference doc that you have to explicitly provide tool callbacks and/or tool callback providers to the chat client.
Closing the issue.

There is simply no such configuration option as "spring.ai.mcp.client.toolcallback.enabled". It's really frustrating.

Had a quick look at the source code and I think that property isn't mapped by any configuration bean, that's way no metadata are generated for it.
But there's a conditional bean wich is activated only if the afore-mentioned property is set to true so that flag is needed in anyway.
