@enesgules you are correct that is the latest one, but you are running curl -L "https://github.com/modelcontextprotocol/registry/releases/download/v1.3.3/mcp-publisher_$(uname -s | tr '[:upper:]' '[:lower:]')_$(uname -m | sed 's/x86_64/amd64/;s/aarch64/arm64/').tar.gz" | tar xz mcp-publisher which is an older version of the mcp-publisher (1.3.3 instead of 1.4.0). I believe if you update that, it should work.

But we should improve the flows here to make error messages more obvious and avoid such breaking changes -- it's fair feedback, thanks for flagging this.

Thanks!

Could you please take a look why this run failed too: https://github.com/upstash/context7/actions/runs/20717015246/job/59470512556
