Help wanted: Claude Code testers

[cmeans-claude-dev]

mcp-clipboard was built for Claude Code — it works around the terminal padding bug that corrupts long commands when you copy them from Claude Code's output. If you use Claude Code, even 10 minutes of testing would be a huge help.

Setup

claude mcp add clipboard -- uvx mcp-clipboard

That's it. Claude Code will discover the tools automatically.

Tests

Clipboard padding workaround

1. Ask Claude Code to generate a long shell command (something with pipes, quotes, or flags)
2. Instead of copying from the terminal, say: "Copy that command to my clipboard"
3. Paste into your terminal — verify it's clean (no leading spaces, no hard line breaks)

Core functionality

• Copy plain text → "read my clipboard" → returns the text
• Copy cells from a spreadsheet → "paste my clipboard" → returns a Markdown table
• Copy a URL → "what's on my clipboard?" → returns the URL cleanly
• Copy some code → "read what I copied" → returns in a code block
• Copy an image → "paste my clipboard" → Claude can see and describe the image
• "Copy this to my clipboard: hello world" → verify it lands on your clipboard

Auto-copy behavior (optional)

Add this to your CLAUDE.md:

When you produce a shell command for the user to run, also copy it to the clipboard using clipboard_copy.

• Verify Claude Code automatically copies commands without being asked

Debug logging

If something doesn't work:

MCP_CLIPBOARD_DEBUG=1 claude

Or run the server standalone:

uvx mcp-clipboard --debug

Platforms

• Linux (Wayland): Tested — this is the primary dev platform
• Linux (X11): Unit tested, unverified on live hardware
• macOS: Implemented, untested (see Help wanted: macOS and Windows testers #5)
• Windows: Implemented, untested (see Help wanted: macOS and Windows testers #5)

How to report

Comment on this issue with:

• Your OS and platform (e.g., macOS 15.3, Fedora 43 Wayland, Windows 11)
• Claude Code version (claude --version)
• What worked / what didn't
• Any error output

Even a "everything worked on macOS" is valuable. Thanks!
