How can I access published custom components on the MCP server in Pipedream?

on the hosted MCP server, when publishing custom components, how do we access them? docs say:

Custom actions that you publish are automatically exposed as tools in the Pipedream MCP server for the relevant app.
passing the app name to the MCP server for a tools list call BASE/v1/:extid/:app , none of these work:
• app = ~ (as per doc)
• app = ~/
• app = the prefix for my component (where I have followed naming conventions, app-someactionname )

some output ID I got from the pd publish if helpful:
sc_1LiRMQwg

I am reusing the google_calendar helpers that supply the app prop (doc) so I believe this should be on google_calendar

I’ve published to both development and production and tried querying both (through the x-pd-environment header bc the environment header values appear to be borked for dev on the python sdk?)

I have not gotten this to work but I’m just gonna go with pure Actions instead of using the MCP server, since I do see my custom Action in that API response

5

maybe it has something to do with the fact that the pipedream sdk version is 1.5.4 in the MCP repo, and the current is 1.7.0?

6

The SDK vers could potentially be an issue? But the app should indeed be something like google_calendar for example. What app did you publish custom tools for?

7

The core issue is that you’re not able to list the tools you published?

8

If you’re using the hosted MCP server can you just use the latest SDK version?

9

Or use the remote MCP server instead? What’s the core use case for self hosting?

• yes, the app was google_calendar

The core issue is that you’re not able to list the tools you published
yep ^ for the app google_calendar

I was using the remote MCP server. for some reason, when I tried to reproduce this underlying SDK call by doing an actions.list on the latest (Python) SDK version, it worked as intended. so I’m all good now!
