Error when calling the Adobe Analytics MCP server.

Hi all!

Has anyone had the time yet to play around with the Adobe Analytics MCP servers (beta)? 

  • created a new AA product profile with “MCP Access” permission, (actually for testing purposes added all permissions)
  • assigned it to my API project in developer.adobe.com
    • what I noticed there is that there does not seem to be a dedicated MCP-scope available, just as a side note, I only see “openid, AdobeID, additional_info.projectedProductContext”

My MCP calls are failing with this error:

  • (UPSTREAM_ERROR | HTTP 502 | {"method":"POST","error":"Proxy error","message":"401 Unauthorized: [no body]","targetUrl":"https://appservice-aamcpserver-prod.ethos11-prod-or1.ethos.adobe.net/mcp","timestamp":1777355456263})

Now I'm wondering whether I need some additional provisioning from the Adobe side to access the MCP servers in the first place? 

Let me know what you think

It’s in Beta… I would be surprised if you didn’t encounter some bugs 🤣

I have not played with it myself… but it almost looks like there may be some additional provisioning needed based on that error….

Yeah that is to be expected. But I even gave my dummy product profile super duper admin rights, and still won’t work. To be clear, not talking about connecting the MCP to a Claude or ChatGPT desktop app. Talking about low-level OAuth server-server connection. 
Asked the #measure slack hive mind as well. Let’s see if anyone has an idea 

Cheers from Switzerland!

    Have you tried using a GET request instead? I get a similar error with a post request, but a get request returns something (not sure if it’s correct though):
