Lets Claude Code, Cursor and other assistants search your CrossPaste clipboard history and save new items to it.

CrossPaste is a clipboard manager for macOS, Windows and Linux that syncs between your own devices without a cloud. Its MCP server is built into the desktop app. Your assistant can search the history, read one item and add new ones.

The server is off by default. Turn it on in CrossPaste's settings, then connect your assistant to the local address it shows. It listens on your own computer only, so the app has to be running.

Good for

  • CrossPaste users who want an assistant to find things they copied earlier
  • Developers who copy a lot of snippets, links and colours
  • Privacy-minded people who want clipboard data kept on their own machine

Install CrossPaste MCP

Claude Code

  1. 1

    Copy this prompt.

    Add the CrossPaste MCP server to Claude Code. Run this command:

claude mcp add crosspaste --transport sse http://localhost:13130/

Then check that it loaded and tell me if I need to sign in or restart.
  2. 2

    Paste it into Claude Code. It shows the change and asks before running it.

Requires CrossPaste desktop app running, MCP server switched on in CrossPaste settings.

Read-only mode: No read-only mode is documented.

Switch on the MCP server in CrossPaste settings first. The address uses the default port 13130, so change it if you set another port.

From the vendor's docs. Source.

Tools

  • Searches or browses your clipboard history

    Lists up to 100 items, newest first, each with its ID, type, source app, size, time and a one-line summary. Add keywords, a type or a tag to narrow the list. Keywords match the start of words.

    Try: “Find the invoice link I copied last week.”

    Read · search_clipboard

  • Shows the full content of one clipboard item

    Returns one item by its ID: the details and the content, which is text, a link and title, a colour value, or file names. It does not return binary data.

    Try: “Show me clipboard item 482.”

    Read · get_paste_item

  • Counts what your clipboard history holds

    Reports the total item count and size, and the count and size for each type, such as text, link, image and file.

    Try: “How big is my clipboard history?”

    Read · get_clipboard_stats

  • Lists the tags on your clipboard items

    Returns every tag with its ID and name. It cannot create, rename or delete tags.

    Try: “What tags do I use for clipboard items?”

    Read · list_tags

  • Adds a new item to your clipboard history

    Creates a history item of type text, link, HTML, RTF, colour, file or image. It does not change your system clipboard or send the item to other devices. For files and images it stores the path, not a copy.

    Try: “Save this snippet to my clipboard history.”

Medium risk

The assistant can read everything you have copied and add items to the history. Clear anything sensitive from your history first, and turn the server off when you are not using it.

What it can do

  • Read your data
  • Create and change things
  • Delete things
  • Read-only mode

Watch out for

  • Your clipboard history can hold secrets

    Passwords, tokens and private text you copied are searchable by the assistant and go to your AI provider. Clear sensitive items before you connect it. github.com

  • Any program on your computer can reach the port

    The server has no sign-in, and listens on 127.0.0.1 only. Other local programs could connect while it is on. Turn it off when you do not need it. github.com

  • It can add items to your history

    The add tool only appends to CrossPaste history and does not touch the system clipboard. For files it stores a path to a file on your machine. github.com

Technical details

Questions

Is the CrossPaste MCP server official?

Yes. It ships inside the CrossPaste desktop app, in the CrossPaste repository.

How do I turn it on?

Open CrossPaste's settings, switch on the MCP server, and optionally set a port. The default port is 13130, and the app shows the exact Claude Code command.

Does my clipboard data leave my computer?

CrossPaste says its sync is local-only. The assistant you connect still receives whatever the tools return, and your AI app sends that to its model provider.

Can it paste into other apps or change my system clipboard?

No. The add tool only appends an item to CrossPaste's history. It does not change the system clipboard or send the item to other devices.

Does it work in Claude Desktop or ChatGPT?

CrossPaste documents only a Claude Code command. The server is a local address, so apps that connect through the cloud cannot reach it. Other local apps may work with the config in the install box.

Does it need to be running?

Yes. The MCP server is part of the desktop app, so CrossPaste must be open with the MCP switch on.

Is it free?

Yes. CrossPaste is open source under AGPL-3.0.
