Clipboard Mcp

Copy an error → ask Claude to fix it → the fix lands in your clipboard. No manual paste into chat, no manual copy from response.

{ "mcpServers": { "clipboard": { "command": "clipboard-mcp" } } }

# Add for current project claude mcp add clipboard clipboard-mcp # Or add globally claude mcp add --scope user clipboard clipboard-mcp

Run as an HTTP server for remote or programmatic access:

clipboard-mcp --http # 127.0.0.1:3100 clipboard-mcp --http --port 8080 # custom port clipboard-mcp --http --host 0.0.0.0 # expose to network (see Security)

"Take whatever is on my clipboard and rewrite it in a more formal tone, then put the result back."

"Watch my clipboard for 60 seconds. When I copy something, summarize it in one sentence."

"Get my clipboard, translate it to German, and set the translation back."

Copy a CSV table → "Convert what's on my clipboard to JSON" → paste formatted JSON into your editor.

Copy a code snippet from a browser → "Review the code on my clipboard for bugs" → Claude reads it directly, no pasting into chat.

Step-by-step agent output via clipboard history:

Run a multi-step task andset_clipboardafter each step. With any clipboard manager (Paste, CopyQ, Klipper), you get a chronological log of every result — browse, search, and review the agent's work without switching windows.

- Windows(x86_64) — clipboard persists via OS pasteboard
- macOS(x86_64, aarch64) — clipboard persists via OS pasteboard
- Linux(x86_64, aarch64) — X11 and Wayland (viawl-data-controlprotocol)

Linux note:On Linux, clipboard content set by the server is kept alive by a background thread. If no clipboard manager is running (bare WMs like i3/dwm), installclipman,parcellite, orcopyq.

Linux: clipboard content disappearsEnsure a clipboard manager is running. On bare window managers (i3, dwm), installclipman,parcellite, orcopyq.

Wayland: "clipboard is empty or contains non-text content"Your compositor must support thewl-data-controlprotocol. Sway, Hyprland, GNOME, and KDE all do. Older compositors may not.

macOS: clipboard access deniedEnsure the terminal running the MCP server has clipboard permissions in System Settings > Privacy & Security.

This server gives connected MCP clients full read/write access to your system clipboard:

- get_clipboard/get_clipboard_html— return clipboard content verbatim
- set_clipboard— silently overwrites clipboard contents (max 1 MB)
- watch_clipboard— returns the next thing you copy, verbatim
- clear_clipboard— wipes clipboard without confirmation

Only connect this server to AI sessions you trust. Do not use it in environments where sensitive data (passwords, tokens) may be on the clipboard.

HTTP mode:Default bind is127.0.0.1(localhost only). Binding to0.0.0.0with--hostexposes clipboard to all reachable network interfaces. Browser-initiated requests (withOriginheader) are rejected with 403. There is no authentication — non-browser HTTP clients are not restricted. For remote access, prefer SSH tunneling over exposing to the network.
