It should be possible to receive ToolListChangedNotification events from Pipedream’s hosted MCP server using SSE right? I currently need to manually refresh the available tools, but I think the Pipedream typescript client uses SSE to get notified on changes?
I don’t see that we’re currently calling tools/list_changed when I test in the MCP inspector, which is slightly surprising to me, I thought we were
Are you using your own MCP client that’s capable of handling tool change notifications and reloading tools?
Yes, I am using the official swift MCP sdk with some tweaks, it supports server-sent events but I am not receiving anything from the Pipedream server so for now I’m force reloading the tools list after every call which doesn’t feel ideal.
Yea I hear you, will check in with the team about that. Honestly I don’t think I’ve come across any MCP client that actually listens for tool change notifications to reload the available tools, but that’s been surprising — it makes so much sense to support tool discovery!
Much appreciated!
