error: could not determine executable to run for package @delorenj/mcp-server-trello

[motiteux]

I am using this mcp (which I find to be the richest Trello MCP in terms of tools - keep doing the great work!) in Claude Desktop.
I integrated it using bun:
json "trello-myproject": { "command": "bunx", "args": ["@delorenj/mcp-server-trello"], "env": { "TRELLO_API_KEY": "REDACTED", "TRELLO_TOKEN": "REDACTED" } }

However, when running claude with this MCP, the MCP fails to load and I get this message in the logs:

It's a shame as it is a blocker: I cannot use this MCP anymore (unless I can find a workable commit)...
