claude unable to find agent via mcp

What I did:

Ran the connection manually to debug:

npx mcp-remote https://v1.mindstudio-api.com/developer/mcp/v1/[MY-ID] --header "Authorization: Bearer [MY-KEY]" --transport http-only

Error returned:

[23672] Connecting to remote server: https://v1.mindstudio-api.com/developer/mcp/v1/[MY-ID]
[23672] Using transport strategy: http-only
[23672] Connection error: Error: Error POSTing to endpoint (HTTP 500): 
{"code":500,"errorString":"There was an error: Cannot destructure property 'billingPlanId' of '(intermediate value)' as it is null."}

What I’ve verified:

  • Workflow is published

  • Start block is set to “Packaged Workflow”

  • Agent ID is listed in MCP Server settings (shows the workflow name and description)

  • I have an active paid plan

This looks like a server-side issue where the MCP endpoint can’t retrieve billing info. Any guidance?

Thanks

Hi @Kev,

Thanks for the post. Could you let me know if you’re on Windows or macOS?
