build: ensure macOS mcpb binary keeps the executable bit - #32
Merged

Conversation
mcpb pack stores each file's unix mode in the .mcpb archive, so the bundled binary is only executable if the source file is. Explicitly chmod +x the macOS universal binary after building; Claude Desktop fails to launch the server if the extracted binary lacks the executable bit. (Windows ignores unix perms.)

Summary
Guarantees the bundled macOS server binary is executable inside the
.mcpb, so Claude Desktop can launch it.Why
mcpb packstores each source file's unix mode in the zip, so the extracted binary is only executable if the file had+xat pack time.go build/lipocurrently produce+x, but this makes it explicit and robust on the CI runner rather than relying on toolchain defaults.Verified the packed archive stores
rwxr-xr-xforserver/godevmcp-darwin(viazipinfo). The Windows.exedoesn't need a unix executable bit, so it's left alone.🤖 Generated with Claude Code
