Let the assistant read your clipboard and write to it — tables stay tables, commands stay clean.

LABSCO SUMMARY

It solves a copy problem you have probably stopped noticing.

Two of them, actually. Spreadsheet cells pasted into a chat arrive as one flat string and the model guesses at the column boundaries; terminal output copied out of a coding agent arrives with padding and hard wraps. Reading the clipboard directly fixes the first, and asking the assistant to copy a command fixes the second. The PRIMARY selection support is Linux only — passing selection="primary" on macOS or Windows returns a clear error rather than silently reading the wrong buffer.

What it is

A clipboard bridge. Instead of pasting into a chat box and losing the structure, the server reads the system clipboard directly — including the HTML that spreadsheet apps put there — and returns a real Markdown table, JSON or CSV. It writes the other way too, putting clean text onto the clipboard for you to paste.

What you get

  • clipboard_paste reads whatever is on the clipboard — tables, text, code, JSON, URLs, images — with include_schema=true to append inferred column types
  • clipboard_copy writes text back, taking an optional mime_type (text/plain by default, also text/html, text/rtf, image/svg+xml)
  • clipboard_copy_markdown puts both rendered HTML and the source on the clipboard, so Slack, Gmail and Notion get rich text while a terminal gets the markup
  • clipboard_copy_image writes a PNG or JPEG from base64 with no re-encoding, validating magic bytes against the declared type
  • clipboard_list_formats reports which MIME types are currently on the clipboard, and clipboard_read_raw returns one of them verbatim
  • clipboard_version reports the running package version, for hosts that do not surface it
  • On Linux, selection="primary" reads the X11/Wayland PRIMARY selection — whatever you have highlighted — leaving your Ctrl-C buffer untouched

Requirements

A Python package runner — pipx and uv are both documented — then register the mcp-clipboard console script. Published on PyPI as mcp-clipboard version 2.6.1, stdio transport. macOS and Windows need nothing else; Linux needs one clipboard utility, wl-clipboard on Wayland (sudo apt install wl-clipboard or sudo dnf install wl-clipboard). No account and no network — it talks to the local clipboard only.

Setup effort

One command — pipx install mcp-clipboard
