MCP client implementation

[jmartisk]

This can be done after we get a LC4j version with langchain4j/langchain4j#2240 in

Idea: We could create a configuration model like this

# one stdio-based MCP server
quarkus.langchain4j.mcp.server.server1.transport-type=stdio
quarkus.langchain4j.mcp.server.server2.command=npm exec @modelcontextprotocol/[email protected]

# and one HTTP-based MCP server
quarkus.langchain4j.mcp.server.server2.transport-type=http
quarkus.langchain4j.mcp.server.server2.sse-url=http://localhost:3000/sse

and Quarkus would automatically generate a Tool provider that is backed by these two servers and register it in CDI to be picked up by AI services automatically

BTW @edeandrea this will be a cool thing for demos :)

@mkouba is working a prototype to create MCP servers. Watch quarkusio/quarkus#45054 for updates
