GetTransport failed: transport not found in response

[ebendl]

I'm using the MCP with Cursor and was trying to get more information about a specific transport.

I can see in Cursor's chat that it Ran GetTransport:sap and that the correct transport number was supplied as a paramater. However, it then got the response GetTransport failed: transport not found in response.

Cursor then decided to check the connection details by running Ran GetconnectionInfo:sap and got the following response:

{
"client": "220",
"debugger_user": "<my user, redacted>",
"features": "✗ hana | ✓ abapgit | ✗ rap | ✗ amdp | ✗ ui5 | ✗ transport",
"mode": "focused",
"url": "http://<my system, redacted>:8040",
"user": "<my user, redacted>"
}

My Cursor MCP.json is:

{
  "mcpServers": {
    "sap": {
      "command": "/Users/<redacted>/vibing-steampunk/vsp",
      "env": {
        "SAP_URL": "http://<my system, redacted>:8040",
        "SAP_USER": "<my user, redacted>",
        "SAP_PASSWORD": "<my pw, redacted>",
        "SAP_CLIENT": "220",
        "SAP_ALLOW_TRANSPORTABLE_EDITS": "true",
        "SAP_ENABLE_TRANSPORTS":"true"
      }
    }
  }
}

Am I doing something wrong?
I should also mention that the transport tool in Eclipse works fine.

I am having a similar problem.

I'm using VSP with Claude Code. In the mcp.json I've included --allow-transportable-edits and --enable-transports. I am not able to return a trasnport list, or am I able to update a transportable zprogram with EditSource or WriteSource. Any help would be much appreciated! Edit: Also, transports in Eclipse work fine using the same user id.

I think you can try with --feature-transport on to your args (or SAP_FEATURE_TRANSPORT=on in env) . I believe this will solve the issue. That said, having two similar flags is a bit confusing and the error message may not be the most helpful one. Might be worth considering either combining them or having --enable-transports automatically imply --feature-transport on.

[ebendl]

Thanks, will try now.

[ebendl]

I tried it, and while the GetTransport tool now returns that

✗ hana | ✓ abapgit | ✗ rap | ✗ amdp | ✗ ui5 | ✓ transport

it still doesn't work. One of my colleagues got the Go code compiled, we'll try and debug it a bit further.

[butlersupply]

Thank you kts982. I tried the --feature-transport on, but transport still returns an empty list. Claude can read programs, but can't edit them.

I'm using this config with within the cursor IDE, with the claude code for vs code plugin

Does your SAP system have ChaRM/Solution Manager integration enabled (transports linked to change documents/projects)?

I reproduced this on a ChaRM-enabled system. The ADT endpoint GET /sap/bc/adt/cts/transportrequests returns empty XML when ChaRM is active.
GetUserTransports has no fallback, so it always fails on these systems.

ListTransports has a SQL fallback that should work — @butlersupply , your ListTransports error (Sibling tool call errored) is perhaps Cursor aborting it because the parallel GetUserTransports call failed first. ListTransports itself may not have run. Could you try calling only ListTransports (without GetUserTransports in the same call) and share the result?

Suggested fix (?): Add an E070/E07T SQL fallback to GetUserTransports (like ListTransports already has ), and add filter parameters (status, type, name pattern) to the SQL query.

Thank you @kts982,

I am not familiar with ChaRM. I will need to dig deeper there. Is the suggest to disable ChaRM and test again?

[kts982]

Thank you @kts982,

No, don’t do that. What you are trying to do? Call specific tool, which one? Can you edit objects in local packages ( no need for transport)?

[butlersupply]

@kts982 thank you so much. I cannot, using claude, make any edits. I'm unable to create or change, even in the $tmp package.

I tested the fr0ster/mcp-abap-adt yesterday, and again was able to see programs but not edit or create. Different errors though. I'm wondering if it has something to do with 740 compatibility? Eclipse adt works fully for me with the same sap user account.

My main goal was to be able to update my z* programs directly using claude code. (I have about 100 programs to refactor)

[AnOffe]

Have the same problem. Can edit and activate with given transport, but GetTransport or ListTransport fails, says no transport for user, even if there are some. I am using claude code.

[butlersupply]

@AnOffe, what SAP_BASIS level is your system? I am on-prem 740 but cannot edit, even by supplying a modifiable transport.

[AnOffeElco]

@butlersupply SAP_BASIS Release 758 SP-Level 0001

[butlersupply]

@AnOffeElco at that basis level you might want to give this mcp a try: https://github.com/fr0ster/mcp-abap-adt

You may have good luck with it as you are at 751 or better.

[AnOffeElco]

@butlersupply Thank you for sharing. I tested the mcp from mario-adreschak. Really good work. Is the one from frOster similar? What are pros and cons against this mcp? I had Issues with complex operations like lock-edit-activate-unlock. This seems to be smoother with this one here.

[butlersupply]

Hi @AnOffeElco,

I'm not familiar with mario-adreschak but will check it out. At 740 basis, we have been unable to get any of the MCP's to work with ADT for lock-edit-activate operations. frOster has been very quick to respond to issues.
