class McpToolGroup(description: ToolGroupDescription, provider: String, name: String, permissions: Set<ToolGroupPermission>, clients: List<<Error class: unknown class>>, filter: (<Error class: unknown class>) -> Boolean, metaConverter: ToolCallContextMcpMetaConverter = ToolCallContextMcpMetaConverter.passThrough()) : ToolGroup
ToolGroup backed by MCP.
Tools are loaded lazily on first access rather than at construction time. This is required when MCP clients are configured with spring.ai.mcp.client.initialized=false so that the user's OAuth token is present in the security context when the MCP handshake occurs.
Kotlin's lazy delegate uses LazyThreadSafetyMode.SYNCHRONIZED by default, so concurrent first-access across threads is safe without additional locking.

provider
Name of the provider of the tool group
name
Name of the tool group

Permissions the tools requires
