agent: mcp

When does this happen?

IF MCP server sends 'notifications/tools/list_changed' notification to indicate tool list has changed.

How others solved it

THEN Implement a handler for 'notifications/tools/list_changed' in the client to refresh the tool list. Use a helper method like the Java SDK's 'toolsListChanged' handler, or set a custom notification handler that updates the list of available tools for the session. Ensure server capabilities include 'tools: { listChanged: true }'.

client.setNotificationHandler('notifications/tools/list_changed', () => { refreshToolList(); });
